What is the difference between DROP,DELETE and TRUNCATE.

2010-07-29T04:52:00.001-07:00

What is difference between TRUNCATE & DELETE?

TRUNCATE is a DDL command and cannot be rolled back. All of the memory space is released back to the server.

DELETE is a DML command and can be rolled back.

Both commands accomplish identical tasks (removing all data from a table), but TRUNCATE is much faster.

TRUNCATE : You can't use WHERE clause

DELETE : You can use WHERE clause

Truncate: Drop all object's statistics and marks like High Water Mark free extents and leave the object really empty with the first extent.

Delete: You can keep object's statistics and all allocated space.

1>TRUNCATE is a DDL command whereas DELETE is a DML command.

2>TRUNCATE is much faster than DELETE.

Reason:When you type DELETE.all the data get copied into the Rollback Tablespace first.then delete operation get performed.Thats why when you type ROLLBACK after deleting a table you can get back the data(The system get it for you from the RollbackTablespace).All this process take time.But when you type TRUNCATE it removes data directly without copying it into the Rollback Tablespace.Thatswhy TRUNCATE is faster.Once you Truncate you cann't get back the data.

3>You cann't rollback in TRUNCATE but in DELETE you can rollback.TRUNCATE removes the record permanently.

4>In case of TRUNCATE Trigger doesn't get fired.But in DML commands like DELETE .Trigger get fired.

5>You cann't use conditions(WHERE clause) in TRUNCATE.But in DELETE you can write conditions using WHERE clause.

truncate is ddl command.its faster than delete as it doesnt  have go through the rollbacks etc.truncate being a ddl is  auto commit.we can only truncate the whole table(cant use  where clause).once table is truncated we cant rollback the  changes.when a table is truncated the memory occupied is  released.that id the water mark is adjusted.  delete is a dml command and can be rolled back.is slower  than truncate as it is dml has to go through rollback  segments etc.we can use where clause with delete.when a  table is deleted memory occupied is not released ans also  the water mark is not adjusted.

What is the difference between DROP,DELETE and TRUNCATE.

Drop and Truncate are DDL With Drop Command we can remove entire Table or columns from database. With Truncate we can remove the records in the table by keeping table structure.

Drop and Truncate are AutoCommit.

By using Delete command we can remove rows in the table but its not autocommit

DELETE
Delete is the command that only remove the data from the table. It is DML statement. Deleted data can be rollback. By using this we can delete whole data from the table(if use without where clause).If ew want to remove only selected data then we should specify condition in the where clause
SQL>delete from employee;(this command will remove all the data from table)
SQL>delete from employee where employee_name='JOHN';(This command will remove only that row from employee table where employee_name is JOHN');

DROP:
Drop command remove the table from data dictionary. This is the DDL statement. We can not recover the table before Oracle 10g. But Oracle 10g provide the command to recover it by using the command (FLASHBACK)

TRUNCATE:
This is the DML command. This command delete the data from table. But there is one difference from ordinary delete command. Truncate command drop the storage held by this table. Drop storage can be use by this table again or some other table. This is the faster command because it directly drop the storage

What is host file?

2010-07-29T04:49:00.001-07:00

What is host file?

The hosts file is a computer file used in an operating system to map hostnames to IP addresses. This method is one of several system facilities to address network nodes on a computer network. On some operating systems, the host file content is used preferentially over other methods, such as the Domain Name System (DNS), but many systems implement name service switches to provide customization. Unlike DNS, the hosts file is under the control of the local computer's administrator.[1]

The hosts file is a plain-text file and is traditionally named hosts.

The short answer is that the Hosts file is like an address book. When you type an address like www.yahoo.com into your browser, the Hosts file is consulted to see if you have the IP address, or "telephone number," for that site. If you do, then your computer will "call it" and the site will open. If not, your computer will ask your ISP's (internet service provider) computer for the phone number before it can "call" that site. Most of the time, you do not have addresses in your "address book," because you have not put any there. Therefore, most of the time your computer asks for the IP address from your ISP to find sites.

If you put ad server names into your Hosts file with your own computer's IP address, your computer will never be able to contact the ad server. It will try to, but it will be simply calling itself and get a "busy signal" of sorts. Your computer will then give up calling the ad server and no ads will be loaded, nor will any tracking take place. Your choices for blocking sites are not just limited to blocking ad servers. You may block sites that serve advertisements, sites that serve objectionable content, or any other site that you choose to block.

Location of HOST File:

Windows 95/98/Me c:\windows\hosts

Windows NT/2000/XP Pro c:\winnt\system32\drivers\etc\hosts

Windows XP Home c:\windows\system32\drivers\etc\hosts

Linux: It present in /etc folder

What is the Difference Between http and https?

2010-07-29T04:42:00.001-07:00

What is the Difference Between http and https?

http is hyper text transfer protocol which is responsible for transmitting and receiving information across the Internet where as https is secure http, which is used exchanging confidential information with a server, which needs to be secured in order to prevent unauthorized access.

HTTP is Hyper Text Transport Protocol and is transmitted over the wire via PORT 80(TCP). You normally use HTTP when you are browsing the web, its not secure, so someone can eavesdrop on the conversation between your computer and the web server.

HTTPS (Hypertext Transfer Protocol over Secure Socket Layer, or HTTP over SSL) is a Web protocol developed by Netscape and built into its browser that encrypts and decrypts user page requests as well as the pages that are returned by the Web server. HTTPS is really just the use of Netscape's Secure Socket Layer (SSL) as a sublayer under its regular HTTP application layering. (HTTPS uses port 443 instead of HTTP port 80 in its interactions with the lower layer, TCP/IP.) SSL uses a 40-bit key size for the RC4 stream encryption algorithm,new-age browsers use 128-bit key size which is more secure than the former, it is considered an adequate degree of encryption for commercial exchange.HTTPS is normally used in login pages, shopping/commercial sites.

Although it may be encrypted does not mean its safe, there are tools out there to decrypt the information being sent over the wire, although its more difficult to do so.

Tables vs DIV Tags: What's the Difference? Which is Better?

2010-07-29T04:41:00.001-07:00

Tables vs DIV Tags: What's the Difference? Which is Better?

Jump into CSS with both feet and don't look back.

Tables were never meant for layout, that's just the way Web sites were developed from the start because they could control layout easier than early CSS and early browsers were VERY hard to make CSS work in.

Building sites using CSS over tables has many advantages:

1. Easy to make sitewide positional and styling changes in one file instead of making a change on 1000 different pages using tables, for example.
2. Reduces the amount of code used to display a page, improving load times, reducing bandwidth, costing you less money (you are allowed specific amounts of bandwidth in your hosting package).
3. CSS helps sites work across many different mediums such as PDAs, Web browsers, and mobile phones.
4. You can easily switch layouts (as described earlier).
5. Future editions of Web browsers will support CSS standards changes.
6. Search engine spiders can get through your site from your CSS text-based navigation.

While you are at it, build your sites using Server-side Includes as well so you can make content changes in one place (the include file) and layout changes in one place (the style sheet).

Lastly, yes, use tables to tabular data.

Hope that helps.

Over the last several years, developers have moved from table-based website structures to div-based structures. Do developers know the reasons for moving to div-based structures?

However, it's a matter of personal preference. That doesn't mean there's anything wrong at all with making a different choice.

Difference Between <Div> tag and <Table> tag

In my opinion, Div tag has a lot of advantage compare to table in terms of page loading speed, crawling your page and SEO friendly. However, tables will make object appear aligned the same in all browsers.

Advantages of Using the <Div> Tag

1.Easily to maintain and organize the site.
2.Webpage with Div tag tends to load faster than table mainly because of less code.
3.It will decrease the code and code to content ratio decreases, Thus, the content is found more easily to bots.

Advantages of <Div> Tag from SEO perspective

Using Div tag is very good for SEO because while you use Tableless layout then you are separating structural and presentational (html and CSS).

As you can see from the above example, the table-based structure contains more code than the div-based structure by a ratio as much as 2:1.

Another drawback to tables is that they make it harder to separate content from design. The border, width, cellpadding and cellspacing tags are used in about 90% of all websites that use tables. This adds code to the HTML that should instead go in the CSS.

More lines of code will slow down the development and raises maintenance costs. There's a limit to how many lines of code a programmer can produce per day, and excess code is more complicated for others to understand.

Besides, more lines of code mean larger file sizes, which mean longer download times. A large code base probably has more bugs.

Disadvantages of Using the <Div> Tag

Using a div for structure can make a page more fragile when content is pushing the DIV to its limit. It can also force columns to fall under each other. But this is usually only happen for older browsers like IE6, I often encounter this issue when changing the whole web layout for my company site.

The Difference Between mysql_fetch_array() And mysql_fetch_assoc() and mysql_fetch_object()

2010-05-14T04:36:00.001-07:00

$rows = mysql_fetch_array( "select name, address from people");

Means you then get each of the row results as a straight array, meaning you dont necessarily need to know in advance the order elements arrive via the select.

foreach( $rows as $row )
echo $row[0] . ' lives at ' . $row[1] ;

$rows = mysql_fetch_assoc( "select name, address from people" );

Means you then get each of the row results as a named array elements, an associative array.

foreach( $rows as $row )
echo $row['name'] . ' lives at ' . $row['address'];

Which is now dependent on you knowing what the result columns are named.

$rows = mysql_fetch_object( "select name, address from people" );

Means you then get each of the row results using the object notation.

foreach( $rows as $row )
echo $row->name . ' lives at ' . $row->address ;

Which again relies upon your knowing what is coming out of the database, and in my opinion is better because a) its easier to read, and b) if you don't use OOP, it at least gets you thinking about and using OO notation.

-----------------------------------------------------------------------------------------------------

There are 3

mysql_fetch_row();
mysql_fetch_assoc();
mysql_fetch_array();

mysql_fetch_row() returns an array with integer indexing. i.e if you get
a result $rec=mysql_fetch_row(SOME RESULT) then you can only get the
result by specifying an integer index like $rec[0], $rec[1] e.t.c

mysql_fetch_assoc() returns an associative array that can only be
accessed by field name e.g. $rec[firstname], $rec[lastname] e.t.c

mysql_fetch_array() returns an associative array that can be accessed by
both of the above methods.

So mysql_fetch_row() will be best for speed but in more recent versions
of php associative arrays are more or less as fast.

Personally I use mysql_fetch_array(); as I like to use both associations
and integers.
-----------------------------------------------------------------------------------------------------

Getting data from MySQL with PHP is very convenient. But I found most of PHP beginners don't know the difference between two MySQL functions: mysql_fetch_array() and mysql_fetch_assoc(). If you don't understand the two functions, you always come up against such problem: why can't I see the result from MySQL?

Suppose we have a database called 'test' and it has a table called 'members' which stores some members' information. The goal is to fetch all the members' information. Consider such code below:

$conn=mysql_connect('localhost','root','');
$mysql_select_db('test');
$rs=mysql_query('SELECT * FROM members');

Then $rs is an array that stores all personal information. You can use mysql_fetch_array() or mysql_fetch_assoc() to fetch each row by calling the function repeatedly. Consider:

while ($row=mysql_fetch_array($rs,MYSQL_NUM)){
// ...
}

Here $row is a normal array (integer-indexed array). You cannot get data with $row['name'], $row['birthday'], etc. You must use integer as the index, e.g. $row[0], $row[1]... How to get an associative array? You need to set the second parameter of mysql_fetch_array(). MYSQL_ASSOC tells mysql_fetch_array() to return an associative array. See below:

while ($row=mysql_fetch_array($rs,MYSQL_ASSOC)){
// ... here you can use $row['name'], $row['birthday']...

}

mysql_fetch_array($rs,MYSQL_BOTH) equals to mysql_fetch_array($rs). There's no need to use MYSQL_BOTH, so we often omit it.

So you can use two methods to fetch data by specifying the second parameter to MYSQL_BOTH or omitting the second parameter. Then both of the styles, $row[0] and $row['name'], are available.

But where's mysql_fetch_assoc()? It seems not useful. Right. mysql_fetch_assoc($rs) is equivalent to mysql_fetch_array($rs,MYSQL_ASSOC). Obviously, when you need to an associated array (string-indexed array) only, mysql_fetch_assoc() is more convenient. By the way, mysql_fetch_assoc doesn't have the second parameter. It can only return associative array so it needs less memory space to store the result array.

Javascript focus() , Text field focus. focus().----> Alternative code to focus()

2010-03-27T00:11:00.001-07:00

Javascript focus()
Text field focus. focus().
Alternative code to focus()
Under IE, when an error occurs the cursor returns to the field with the error. Under Firefox, the cursor stays in the next (tabbed to) field. Is there a way to code this validation so that it would work for both??

Program:
<html>
<head>
<script language='javascript'>
function check()
{
    alert('hii');
    //document.joe.burns.focus(); This is valid for only internet explorer. And will not work on Firefox
    document.getElementById("

burns").focus();
setTimeout("document.getElementById('burns').focus();",0);
}
function check2()
{
var letters2 = document.joe.tammy.value.length +1;
if (letters2 <= 4)
{document.joe.tammy.focus()}
else
{document.joe.chloe.focus()}
}

</script>

Javascript Questions and Answers

2009-09-11T04:02:00.000-07:00

1. What is JavaScript?
A1: JavaScript is a general-purpose programming language designed to let programmers of all skill levels control the behavior of software objects. The language is used most widely today in Web browsers whose software objects tend to represent a variety of HTML elements in a document and the document itself. But the language can be--and is--used with other kinds of objects in other environments. For example, Adobe Acrobat Forms uses JavaScript as its underlying scripting language to glue together objects that are unique to the forms generated by Adobe Acrobat. Therefore, it is important to distinguish JavaScript, the language, from the objects it can communicate with in any particular environment. When used for Web documents, the scripts go directly inside the HTML documents and are downloaded to the browser with the rest of the HTML tags and content.

A2:JavaScript is a platform-independent,event-driven, interpreted client-side scripting and programming language developed by Netscape Communications Corp. and Sun Microsystems.

2. How is JavaScript different from Java?
JavaScript was developed by Brendan Eich of Netscape; Java was developed at Sun Microsystems. While the two languages share some common syntax, they were developed independently of each other and for different audiences. Java is a full-fledged programming language tailored for network computing; it includes hundreds of its own objects, including objects for creating user interfaces that appear in Java applets (in Web browsers) or standalone Java applications. In contrast, JavaScript relies on whatever environment it's operating in for the user interface, such as a Web document's form elements.
JavaScript was initially called LiveScript at Netscape while it was under development. A licensing deal between Netscape and Sun at the last minute let Netscape plug the "Java" name into the name of its scripting language. Programmers use entirely different tools for Java and JavaScript. It is also not uncommon for a programmer of one language to be ignorant of the other. The two languages don't rely on each other and are intended for different purposes. In some ways, the "Java" name on JavaScript has confused the world's understanding of the differences between the two. On the other hand, JavaScript is much easier to learn than Java and can offer a gentle introduction for newcomers who want to graduate to Java and the kinds of applications you can develop with it.

3. What’s relationship between JavaScript and ECMAScript?
ECMAScript is yet another name for JavaScript (other names include LiveScript). The current JavaScript that you see supported in browsers is ECMAScript revision 3.

4. How do you submit a form using Javascript?
Use document.forms[0].submit();
(0 refers to the index of the form – if you have more than one form in a page, then the first one has the index 0, second has index 1 and so on).

5. How do we get JavaScript onto a web page?
You can use several different methods of placing javascript in you pages.
You can directly add a script element inside the body of page.
1. For example, to add the "last updated line" to your pages, In your page text, add the following:
lessthanpgreaterthanblah, blah, blah, blah, blah.lessthan/pgreaterthan
lessthanscript type="text/javascript" greaterthan
lessthan!-- Hiding from old browsers
document.write("Last Updated:" +
document.lastModified);
document.close();
// --greaterthan
lessthan/scriptgreaterthan
lessthanpgreaterthanyada, yada, yada.lessthan/pgreaterthan

(Note: the first comment, "lessthan--" hides the content of the script from browsers that don't understand javascript. The "// --greaterthan" finishes the comment. The "//" tells javascript that this is a comment so javascript doesn't try to interpret the "--greaterthan". If your audience has much older browsers, you should put this comments inside your javascript. If most of your audience has newer browsers, the comments can be omitted. For brevity, in most examples here the comments are not shown. )
The above code will look like this on Javascript enabled browsers,
2. Javascript can be placed inside the lessthanheadgreaterthan element
Functions and global variables typically reside inside the lessthanheadgreaterthan element.
lessthanheadgreaterthan
lessthantitlegreaterthanDefault Test Pagelessthan/titlegreaterthan
lessthanscript language="JavaScript" type="text/javascript"greaterthan
var myVar = "";
function timer(){setTimeout('restart()',10);}

3. Javascript can be referenced from a separate file
Javascript may also a placed in a separate file on the server and referenced from an HTML page. (Don't use the shorthand ending "lessthanscript ... /greaterthan). These are typically placed in the lessthanheadgreaterthan element.
lessthanscript type="text/javascript" SRC="myStuff.js"greaterthanlessthan/scriptgreaterthan

6. How to read and write a file using javascript?
I/O operations like reading or writing a file is not possible with client-side javascript. However , this can be done by coding a Java applet that reads files for the script.

7. How to detect the operating system on the client machine?
In order to detect the operating system on the client machine, the navigator.appVersion
string (property) should be used.

8. How can JavaScript make a Web site easier to use? That is, are there certain JavaScript techniques that make it easier for people to use a Web site?
JavaScript's greatest potential gift to a Web site is that scripts can make the page more immediately interactive, that is, interactive without having to submit every little thing to the server for a server program to re-render the page and send it back to the client. For example, consider a top-level navigation panel that has, say, six primary image map links into subsections of the Web site. With only a little bit of scripting, each map area can be instructed to pop up a more detailed list of links to the contents within a subsection whenever the user rolls the cursor atop a map area. With the help of that popup list of links, the user with a scriptable browser can bypass one intermediate menu page. The user without a scriptable browser (or who has disabled JavaScript) will have to drill down through a more traditional and time-consuming path to the desired content.

9. How can JavaScript be used to improve the "look and feel" of a Web site? By the same token, how can JavaScript be used to improve the user interface?
On their own, Web pages tend to be lifeless and flat unless you add animated images or more bandwidth-intensive content such as Java applets or other content requiring plug-ins to operate (ShockWave and Flash, for example).
Embedding JavaScript into an HTML page can bring the page to life in any number of ways. Perhaps the most visible features built into pages recently with the help of JavaScript are the so-called image rollovers: roll the cursor atop a graphic image and its appearance changes to a highlighted version as a feedback mechanism to let you know precisely what you're about to click on. But there are less visible yet more powerful enhancements to pages that JavaScript offers.
Interactive forms validation is an extremely useful application of JavaScript. While a user is entering data into form fields, scripts can examine the validity of the data--did the user type any letters into a phone number field?, for instance. Without scripting, the user has to submit the form and let a server program (CGI) check the field entry and then report back to the user. This is usually done in a batch mode (the entire form at once), and the extra transactions take a lot of time and server processing power. Interactive validation scripts can check each form field immediately after the user has entered the data, while the information is fresh in the mind.
Another helpful example is embedding small data collections into a document that scripts can look up without having to do all the server programming for database access. For instance, a small company could put its entire employee directory on a page that has its own search facility built into the script. You can cram a lot of text data into scripts no larger than an average image file, so it's not like the user has to wait forever for the data to be downloaded.
Other examples abound, such as interactive tree-structure tables of contents. More modern scriptable browsers can be scripted to pre-cache images during the page's initial download to make them appear lickety-split when needed for image swapping. I've even written some multi-screen interactive applications that run entirely on the client, and never talk to the server once everything is downloaded.

10. What are JavaScript types?
Number, String, Boolean, Function, Object, Null, Undefined.

11. How do you convert numbers between different bases in JavaScript?
Use the parseInt() function, that takes a string as the first parameter, and the base as a second parameter. So to convert hexadecimal 3F to decimal, use parseInt ("3F", 16);
12. How to create arrays in JavaScript?
We can declare an array like this
var scripts = new Array();
We can add elements to this array like this

scripts[0] = "PHP";
scripts[1] = "ASP";
scripts[2] = "JavaScript";
scripts[3] = "HTML";

Now our array scrips has 4 elements inside it and we can print or access them by using their index number. Note that index number starts from 0. To get the third element of the array we have to use the index number 2 . Here is the way to get the third element of an array.
document.write(scripts[2]);
We also can create an array like this
var no_array = new Array(21, 22, 23, 24, 25);

13. How do you target a specific frame from a hyperlink?
Include the name of the frame in the target attribute of the hyperlink. lessthana href=”mypage.htm” target=”myframe”greaterthangreaterthanMy Pagelessthan/agreaterthan

14. What is a fixed-width table and its advantages?
Fixed width tables are rendered by the browser based on the widths of the columns in the first row, resulting in a faster display in case of large tables. Use the CSS style table-layout:fixed to specify a fixed width table.
If the table is not specified to be of fixed width, the browser has to wait till all data is downloaded and then infer the best width for each of the columns. This process can be very slow for large tables.

15. Example of using Regular Expressions for syntax checking in JavaScript

...
var re = new RegExp("^(&[A-Za-z_0-9]{1,}=[A-Za-z_0-9]{1,})*$");
var text = myWidget.value;
var OK = re.test(text);
if( ! OK ) {
alert("The extra parameters need some work.\r\n Should be something like: \"&a=1&c=4\"");
}

16. How to add Buttons in JavaScript?
The most basic and ancient use of buttons are the "submit" and "clear", which appear slightly before the Pleistocene period. Notice when the "GO!" button is pressed it submits itself to itself and appends the name in the URL.
lessthanform action="" name="buttonsGalore" method="get"greaterthan
Your Name: lessthaninput type="text" name="mytext" /greaterthan
lessthanbr /greaterthan
lessthaninput type="submit" value="GO!" /greaterthan
lessthaninput type="reset" value="Clear All" /greaterthan
lessthan/formgreaterthan

Another useful approach is to set the "type" to "button" and use the "onclick" event.
lessthanscript type="text/javascript"greaterthan
function displayHero(button) {
alert("Your hero is \""+button.value+"\".");
}
lessthan/scriptgreaterthan

lessthanform action="" name="buttonsGalore" method="get"greaterthan
lessthanfieldset style="margin: 1em; text-align: center;"greaterthan
lessthanlegendgreaterthanSelect a Herolessthan/legendgreaterthan
lessthaninput type="button" value="Agamemnon" onclick="displayHero(this)" /greaterthan
lessthaninput type="button" value="Achilles" onclick="displayHero(this)" /greaterthan
lessthaninput type="button" value="Hector" onclick="displayHero(this)" /greaterthan
lessthandiv style="height: 1em;" /greaterthan
lessthan/fieldsetgreaterthan
lessthan/formgreaterthan

17. Where are cookies actually stored on the hard disk?
This depends on the user's browser and OS.
In the case of Netscape with Windows OS,all the cookies are stored in a single file called

cookies.txt
c:\Program Files\Netscape\Users\username\cookies.txt
In the case of IE,each cookie is stored in a separate file namely username@website.txt.
c:\Windows\Cookies\username@Website.txt
18. What can javascript programs do?
Generation of HTML pages on-the-fly without accessing the Web server. The user can be given control over the browser like User input validation Simple computations can be performed on the client's machine The user's browser, OS, screen size, etc. can be detected Date and Time Handling

19. How to set a HTML document's background color?
document.bgcolor property can be set to any appropriate color.

20. How can JavaScript be used to personalize or tailor a Web site to fit individual users?
JavaScript allows a Web page to perform "if-then" kinds of decisions based on browser version, operating system, user input, and, in more recent browsers, details about the screen size in which the browser is running. While a server CGI program can make some of those same kinds of decisions, not everyone has access to or the expertise to create CGI programs. For example, an experienced CGI programmer can examine information about the browser whenever a request for a page is made; thus a server so equipped might serve up one page for Navigator users and a different page for Internet Explorer users. Beyond browser and operating system version, a CGI program can't know more about the environment. But a JavaScript-enhanced page can instruct the browser to render only certain content based on the browser, operating system, and even the screen size.
Scripting can even go further if the page author desires. For example, the author may include a preference screen that lets the user determine the desired background and text color combination. A script can save this information on the client in a well-regulated local file called a cookie. The next time the user comes to the site, scripts in its pages look to the cookie info and render the page in the color combination selected previously. The server is none the wiser, nor does it have to store any visitor-specific information.

21. Are you concerned that older browsers don't support JavaScript and thus exclude a set of Web users? individual users?
Fragmentation of the installed base of browsers will only get worse. By definition, it can never improve unless absolutely everyone on the planet threw away their old browsers and upgraded to the latest gee-whiz versions. But even then, there are plenty of discrepancies between the scriptability of the latest Netscape Navigator and Microsoft Internet Explorer.
The situation makes scripting a challenge, especially for newcomers who may not be aware of the limitations of earlier browsers. A lot of effort in my books and ancillary material goes toward helping scripters know what features work in which browsers and how to either workaround limitations in earlier browsers or raise the compatibility common denominator.
Designing scripts for a Web site requires making some hard decisions about if, when, and how to implement the advantages scripting offers a page to your audience. For public Web sites, I recommend using scripting in an additive way: let sufficient content stand on its own, but let scriptable browser users receive an enhanced experience, preferably with the same HTML document.

22. What does isNaN function do?
Return true if the argument is not a number.

23. What is negative infinity?
It’s a number in JavaScript, derived by dividing negative number by zero.

24. In a pop-up browser window, how do you refer to the main browser window that opened it?
Use window.opener to refer to the main window from pop-ups.
(Continued on next part...)
25. What is the data type of variables of in JavaScript?
All variables are of object type in JavaScript.

26. Methods GET and POST in HTML forms - what's the difference?.
GET: Parameters are passed in the querystring. Maximum amount of data that can be sent via the GET method is limited to about 2kb.
POST: Parameters are passed in the request body. There is no limit to the amount of data that can be transferred using POST. However, there are limits on the maximum amount of data that can be transferred in one name/value pair.

27.How to write a script for "Select" lists using javascript
1. To remove an item from a list set it to null
mySelectObject.options[3] = null;
2. To truncate a list set its length to the maximum size you desire
mySelectObject.length = 2;
3. To delete all options in a select object set the length to 0.
mySelectObject.leng

28. Text From Your Clipboard?
It is true, text you last copied for pasting (copy & paste) can be stolen when you visit web sites using a combination of JavaScript and ASP (or PHP, or CGI) to write your possible sensitive data to a database on another server.

29. What does the "Access is Denied" IE error mean?
The "Access Denied" error in any browser is due to the following reason.
A javascript in one window or frame is tries to access another window or frame whose
document's domain is different from the document containing the script.

30. Is a javascript script faster than an ASP script?
Yes.Since javascript is a client-side script it does require the web server's help for its
computation,so it is always faster than any server-side script like ASP,PHP,etc..
31. Are Java and JavaScript the Same?
No.java and javascript are two different languages.
Java is a powerful object - oriented programming language like C++,C whereas Javascript is a
client-side scripting language with some limitations.

32. How to embed javascript in a web page?
javascript code can be embedded in a web page between lessthanscript
langugage="javascript"greaterthanlessthan/scriptgreaterthan tags

33. What and where are the best JavaScript resources on the Web?
The Web has several FAQ areas on JavaScript. The best place to start is something called the meta-FAQ [14-Jan-2001 Editor's Note: I can't point to it anymore, it is broken!], which provides a high-level overview of the JavaScript help available on the Net. As for fact-filled FAQs, I recommend one maintained by Martin Webb and a mini-FAQ that I maintain.
For interactive help with specific problems, nothing beats the primary JavaScript Usenet newsgroup, comp.lang.javascript. Depending on my work backlog, I answer questions posted there from time to time. Netscape and Microsoft also have vendor-specific developer discussion groups as well as detailed documentation for the scripting and object model implementations.

34. What are the problems associated with using JavaScript, and are there JavaScript techniques that you discourage?
Browser version incompatibility is the biggest problem. It requires knowing how each scriptable browser version implements its object model. You see, the incompatibility rarely has to do with the core JavaScript language (although there have been improvements to the language over time); the bulk of incompatibility issues have to do with the object models that each browser version implements. For example, scripters who started out with Navigator 3 implemented the image rollover because it looked cool. But they were dismayed to find out that the image object wasn't scriptable in Internet Explorer 3 or Navigator 2. While there are easy workarounds to make this feature work on newer browsers without disturbing older ones, it was a painful learning experience for many.
The second biggest can of worms is scripting connections between multiple windows. A lot of scripters like to have little windows pop up with navigation bars or some such gizmos. But the object models, especially in the older browser versions, don't make it easy to work with these windows the minute you put a user in front of them--users who can manually close windows or change their stacking order. More recently, a glitch in some uninstall routines for Windows 95 applications can disturb vital parts of the system Registry that Internet Explorer 4 requires for managing multiple windows. A scripter can't work around this problem, because it's not possible to detect the problem in a user's machine. I tend to avoid multiple windows that interact with each other. I think a lot of inexperienced Web surfers can also get confused by them.

35. What boolean operators does JavaScript support?
&&, || and !

36. What does "1"+2+4 evaluate to?
Since 1 is a string, everything is a string, so the result is 124.
37. What are the ways to emit client-side JavaScript from server-side code in ASP.NET?
The Page object in ASP.NET has two methods that allow emitting of client-side JavaScript:
RegisterClientScriptBlock and RegisterStartupScript.
Example usage:
Page.RegisterClientScriptBlock("ScriptKey", "lessthanscript language=javascriptgreaterthan" + "function TestFn() { alert('Clients-side JavaScript'); }lessthan/scriptgreaterthan");
Page.RegisterStartupScript("ScriptKey", "lessthanscript language=javascriptgreaterthan" + "function TestFn() { alert('Clients-side JavaScript'); }lessthan/scriptgreaterthan");
ScriptKey is used to suppress the same JavaScript from being emitted more than once. Multiple calls to RegisterClientScriptBlock or RegisterStartupScript with the same value of ScriptKey emit the script only once, on the first call.

38. What is the difference between RegisterClientScriptBlock and RegisterStartupScript?
RegisterClientScriptBlock emits the JavaScript just after the opening
Top of Form
tag. RegisterStartupScript emits the JavaScript at the bottom of the ASP.NET page just before the closing
Bottom of Form
tag.

39. What is the difference between a web-garden and a web-farm?
Web-garden - An IIS6.0 feature where you can configure an application pool as a web-garden and also specify the number of worker processes for that pool. It can help improve performance in some cases.
Web-farm - a general term referring to a cluster of physically separate machines, each running a web-server for scalability and performance (contrast this with web-garden which refers to multiple processes on one single physical machine).

40. How to get the contents of an input box using Javascript?
Use the "value" property.
var myValue = window.document.getElementById("MyTextBox").value;

41. How to determine the state of a checkbox using Javascript?

43. How to access an external javascript file that is stored externally and not embedded?
This can be achieved by using the following tag between head tags or between body tags.
lessthanscript src="abc.js"greaterthanlessthan/scriptgreaterthanHow to access an external javascript file that is stored externally and not embedded? where abc.js is the external javscript file to be accessed.

44. What is the difference between an alert box and a confirmation box?
An alert box displays only one button which is the OK button whereas the Confirm box
displays two buttons namely OK and cancel.

45. What is a prompt box?
A prompt box allows the user to enter input by providing a text box.

46. Can javascript code be broken in different lines?
Breaking is possible within a string statement by using a backslash \ at the end but not within any other javascript statement.
that is ,
document.write("Hello \ world");
is possible but not document.write \
("hello world");

47. Taking a developer’s perspective, do you think that that JavaScript is easy to learn and use?
One of the reasons JavaScript has the word "script" in it is that as a programming language, the vocabulary of the core language is compact compared to full-fledged programming languages. If you already program in Java or C, you actually have to unlearn some concepts that had been beaten into you. For example, JavaScript is a loosely typed language, which means that a variable doesn't care if it's holding a string, a number, or a reference to an object; the same variable can even change what type of data it holds while a script runs.
The other part of JavaScript implementation in browsers that makes it easier to learn is that most of the objects you script are pre-defined for the author, and they largely represent physical things you can see on a page: a text box, an image, and so on. It's easier to say, "OK, these are the things I'm working with and I'll use scripting to make them do such and such," instead of having to dream up the user interface, conceive of and code objects, and handle the interaction between objects and users. With scripting, you tend to write a _lot_ less code.

48. What Web sites do you feel use JavaScript most effectively (i.e., best-in-class examples)? The worst?
The best sites are the ones that use JavaScript so transparently, that I'm not aware that there is any scripting on the page. The worst sites are those that try to impress me with how much scripting is on the page.
(Continued on next part...)
49. How about 2+5+"8"?
Since 2 and 5 are integers, this is number arithmetic, since 8 is a string, it’s concatenation, so 78 is the result.

50. What is the difference between SessionState and ViewState?
ViewState is specific to a page in a session. Session state refers to user specific data that can be accessed across all pages in the web application.

51. What does the EnableViewStateMac setting in an aspx page do?
Setting EnableViewStateMac=true is a security measure that allows ASP.NET to ensure that the viewstate for a page has not been tampered with. If on Postback, the ASP.NET framework detects that there has been a change in the value of viewstate that was sent to the browser, it raises an error - Validation of viewstate MAC failed.
Use lessthan%@ Page EnableViewStateMac="true"%greaterthan to set it to true (the default value, if this attribute is not specified is also true) in an aspx page.

52. How to Accessing Elements using javascript?
To do something interesting with HTML elements, we must first be able to uniquely identify which element we want. In the example
lessthanbodygreaterthan
lessthanform action=""greaterthan
lessthaninput type="button" id="useless" name="mybutton" value="doNothing" /greaterthan
lessthan/formgreaterthan
lessthan/bodygreaterthan

We can use the "getElementById" method (which is generally preferred)
document.getElementById("useless").style.color = "red";
or we can use the older hierarchical navigation method,
document.forms[0].mybutton.style.color = "blue";
Notice that this uses the "name" attribute of the element to locate it.
# Example of Accessing Elements in a DOM.

lessthanscript type="text/javascript" greaterthan

58. What does javascript null mean?
The null value is a unique value representing no value or no object.
It implies no object,or null string,no valid boolean value,no number and no array object.

59. How do you create a new object in JavaScript?
var obj = new Object(); or var obj = {};

60. How do you assign object properties?
obj["age"] = 17 or obj.age = 17.

61. What’s a way to append a value to an array?
arr[arr.length] = value;

62. What is this keyword?
It refers to the current object.

63. What does the term sticky session mean in a web-farm scenario? Why would you use a sticky session? What is the potential disadvantage of using a sticky session?
Sticky session refers to the feature of many commercial load balancing solutions for web-farms to route the requests for a particular session to the same physical machine that serviced the first request for that session. This is mainly used to ensure that a in-proc session is not lost as a result of requests for a session being routed to different servers. Since requests for a user are always routed to the same machine that first served the request for that session, sticky sessions can cause uneven load distribution across servers.
(Continued on next part...)
64. You have an ASP.NET web application running on a web-farm that does not use sticky sessions - so the requests for a session are not guaranteed to be served the same machine. Occasionally, the users get error message Validation of viewstate MAC failed. What could be one reason that is causing this error?
The most common reason for this error is that the the machinekey value in machine.config is different for each server. As a result, viewstate encoded by one machine cannot be decoded by another. To rectify this, edit the machine.config file on each server in the web-farm to have the same value for machinekey.

65. To set all checkboxes to true using JavaScript?

70. Does javascript have the concept level scope?
No.Javascript does not have block level scope,all the variables declared inside a function possess the same level of scope unlike c,c++,java.

71. What are undefined and undeclared variables?
Undeclared variables are those that are not declared in the program (do not exist at all),trying to read their values gives runtime error.But if undeclared variables are assigned then implicit declaration is done .
Undefined variables are those that are not assigned any value but are declared in the program.Trying to read such variables gives special value called undefined value.

84. How to open a window with no toolbar, but with the location object.
window.open("http://www.mysite.org/Misc/Pennies","Pennies","resizable=yes,status=yes,toolbar=yes,location=yes,menubar=yes,scrollbars=yes,width=800,height=400");

85. How to setting a cookie with the contents of a textbox ?
Values stored in cookies may not have semicolons, commas, or spaces. You should use the handy "escape()" function to encode the values, and "unescape()" to retrieve them.

//Sets cookie of current value for myTextBox
function TextBoxOnchange() {
var myBox = window.document.getElementById(myTextBox");
document.cookie = "myTextBox="+ escape(myBox.value) + getExpirationString();
}

//return a string like ";expires=Thu, 5 Jan 2006 16:07:52 UTC"
function getExpirationString() {
var exp = new Date();
var threemonths = exp.getTime()+(120*24*60*60*1000);
exp.setTime(threemonths);
return ";expires="+exp.toGMTString();
}

This is called from the event handler in the HTML.

lessthaninput name="myTextBox" type="text" id="myTextBox"
onchange="javascript:TextBoxOnchange()" /greaterthan

86. How to getting values from cookies to set widgets?
function getCookieData(labelName) {
//from Danny Goodman
var labelLen = labelName.length;
// read cookie property only once for speed
var cookieData = document.cookie;
var cLen = cookieData.length;
var i = 0;
var cEnd;
while (i lessthan cLen) {
var j = i + labelLen;
if (cookieData.substring(i,j) == labelName) {
cEnd = cookieData.indexOf(";",j);
if (cEnd == -1) {
cEnd = cookieData.length;
}
return unescape(cookieData.substring(j+1, cEnd));
}
i++;
}
return "";
}

//init() is called from the body tag onload function.
function init() {
setValueFromCookie("brand");
setValueFromCookie("market");
setValueFromCookie("measure");
}

function setValueFromCookie(widget) {
if( getCookieData(widget) != "") {
document.getElementById(widget).value = getCookieData(widget);
}
}

//if you name your cookies the widget ID, you can use the following helper function
function setCookie(widget) {
document.cookie = widget + "=" +
escape(document.getElementById(widget).value) + getExpirationString();
}

87. How to Handle Event Handlers?
You can add an event handler in the HTML definition of the element like this,
lessthanscript type="text/javascript"greaterthanlessthan!--
function hitme() {
alert("I've been hit!");
}
// --greaterthan
lessthan/scriptgreaterthan
lessthaninput type="button" id="hitme" name="hitme" value="hit me" onclick="hitme()"

Or, interestingly enough you can just assign the event's name on the object directly with a reference to the method you want to assign.

lessthaninput type="button" id="hitme2" name="hitme2" value="hit me2"/greaterthan
lessthanscript type="text/javascript"greaterthanlessthan!--
function hitme2() {
alert("I've been hit too!");
}
document.getElementById("hitme2").onclick = hitme2;
// --greaterthan
lessthan/scriptgreaterthan

You can also use an anonymous method like this:

document.getElementById("hitme3").onclick = function () { alert("howdy!"); }

You can also use the the W3C addEvventListener() method, but it does not work in IE yet:

lessthaninput type="button" id="hitme4" name="hitme4" value="hit me4"/greaterthan
lessthanscript type="text/javascript"greaterthanlessthan!--
function hitme4() {
alert("I've been hit four!");
}
if(document.getElementById("hitme4").addEventListener) {
document.getElementById("hitme4").addEventListener("click", hitme4, false);
}
// --greaterthan
lessthan/scriptgreaterthan

88. How to remove the event listener:
lessthanscript type="text/javascript"greaterthanlessthan!--
document.getElementById("hitme4").removeEventListener("click", hitme4, false);
// --greaterthan
lessthan/scriptgreaterthan

Key Events

"onkeydown", "onkeypress", "onkeyup" events are supported both in ie and standards-based browsers.

lessthanscript type="text/javascript"greaterthan
function setStatus(name,evt) {
evt = (evt) ? evt : ((event) ? event : null); /* ie or standard? */
var charCode = evt.charCode;
var status = document.getElementById("keyteststatus");
var text = name +": "+evt.keyCode;
status.innerHTML = text;
status.textContent = text;
}
lessthan/scriptgreaterthan
lessthanform action=""greaterthan
lessthaninput type="text" name="keytest" size="1" value=""
onkeyup="setStatus('keyup',event)"
onkeydown="setStatus('keydown',event)"
/greaterthan
lessthanp id="keyteststatus"greaterthanstatuslessthan/pgreaterthan

89. How to change style on an element?
Between CSS and javascript is a weird symmetry. CSS style rules are layed on top of the DOM. The CSS property names like "font-weight" are transliterated into "myElement.style.fontWeight". The class of an element can be swapped out. For example:
document.getElementById("myText").style.color = "green";
document.getElementById("myText").style.fontSize = "20";
-or-
document.getElementById("myText").className = "regular";

90. How to make elements invisible
Change the "visibility" attribute of the style object associated with your element. Remember that a hidden element still takes up space, use "display" to make the space disappear as well.

if ( x == y) {
myElement.style.visibility = 'visible';
} else {
myElement.style.visibility = 'hidden';
}

91. How to set the cursor to wait.
In theory, we should cache the current state of the cursor and then put it back to its original state.
document.body.style.cursor = 'wait';
//do something interesting and time consuming
document.body.style.cursor = 'auto';

92. How to reload the current page
window.location.reload(true);

93. how to force a page to go to another page using JavaScript?
lessthanscript language="JavaScript" type="text/javascript" greaterthanlessthan!-- location.href="http://newhost/newpath/newfile.html"; //--greaterthanlessthan/scriptgreaterthan
94. How to convert a string to a number using JavaScript?
You can use the parseInt() and parseFloat() methods. Notice that extra letters following a valid number are ignored, which is kinda wierd but convenient at times.
parseInt("100") ==greaterthan 100
parseFloat("98.6") ==greaterthan 98.6
parseFloat("98.6 is a common temperature.") ==greaterthan 98.6
parseInt("aa") ==greaterthan Nan //Not a Number
parseInt("aa",16) ==greaterthan 170 //you can supply a radix or base

95. How to convert numbers to strings using JavaScript?
You can prepend the number with an empty string
var mystring = ""+myinteger;
or
var mystring = myinteger.toString();
You can specify a base for the conversion,
var myinteger = 14;
var mystring = myinteger.toString(16);

mystring will be "e".

96. How to test for bad numbers using JavaScript?
the global method, "isNaN()" can tell if a number has gone bad.
var temperature = parseFloat(myTemperatureWidget.value);
if(!isNaN(temperature)) {
alert("Please enter a valid temperature.");
}

97. What's Math Constants and Functions using JavaScript?
The Math object contains useful constants such as Math.PI, Math.E
Math also has a zillion helpful functions.
Math.abs(value); //absolute value
Math.max(value1, value2); //find the largest
Math.random() //generate a decimal number between 0 and 1
Math.floor(Math.random()*101) //generate a decimal number between 0 and 100

98. What's the Date object using JavaScript?
Time inside a date object is stored as milliseconds since Jan 1, 1970.
new Date(06,01,02) // produces "Fri Feb 02 1906 00:00:00 GMT-0600 (Central Standard Time)"
new Date(06,01,02).toLocaleString() // produces "Friday, February 02, 1906 00:00:00"
new Date(06,01,02) - new Date(06,01,01) // produces "86400000"

99. What does the delete operator do?
The delete operator is used to delete all the variables and objects used in the program ,but it does not delete variables declared with var keyword.

100. How tp create Arrays using JavaScript??
lessthanscript type="text/javascript"greaterthan
var days = new Array();
days[0] = "Sunday"
days[1] = "Monday"
days[2] = "Tuesday"
days[3] = "Wednesday"
days[4] = "Thursday"
days[5] = "Friday"
days[6] = "Saturday"

document.write("first day is "+days[0])
lessthan/scriptgreaterthan

This produces

first day is Sunday

A more compact way of creating an array is the literal notation:
lessthanscript type="text/javascript"greaterthan
var days = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];
document.write("first day is "+days[0]) lessthan/scriptgreaterthan
This produces
first day is Sunday

101. How to delete an entry using JavaScript?
The "delete" operator removes an array element, but oddly does not change the size of the array.
lessthanscript type="text/javascript"greaterthan
var days = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];
document.write("Number of days:"+days.length); delete days[4];
document.write("lessthanbr /greaterthanNumber of days:"+days.length);
lessthan/scriptgreaterthan
This produces
Number of days:7
Number of days:7

102. How to use strings as array indexes using JavaScript?
Javascript does not have a true hashtable object, but through its wierdness, you can use the array as a hashtable.

lessthanscript type="text/javascript"greaterthan
var days = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];

for(var i=0; i lessthan days.length; i++) {
days[days[i]] = days[i];
}

document.write("days[\"Monday\"]:"+days["Monday"]);
lessthan/scriptgreaterthan
This produces
days["Monday"]:Monday

103. How to use "join()" to create a string from an array using JavaScript?
"join" concatenates the array elements with a specified seperator between them.

lessthanscript type="text/javascript"greaterthan
var days = ["Sunday","Monday","Tuesday","Wednesday", "Thursday","Friday","Saturday"];
document.write("days:"+days.join(","));
lessthan/scriptgreaterthan
This produces
days:Sunday,Monday,Tuesday,Wednesday,Thursday,Friday,Saturday

104. How to make a array as a stack using JavaScript?
The pop() and push() functions turn a harmless array into a stack

lessthanscript type="text/javascript"greaterthan
var numbers = ["one", "two", "three", "four"];
numbers.push("five");
numbers.push("six");
document.write(numbers.pop());
document.write(numbers.pop());
document.write(numbers.pop());
lessthan/scriptgreaterthan
This produces
sixfivefour
(Continued on next part...)
...)
105. How to shift and unshift using JavaScript?
lessthanscript type="text/javascript"greaterthan
var numbers = ["one", "two", "three", "four"];
numbers.unshift("zero");
document.write(" "+numbers.shift());
document.write(" "+numbers.shift());
document.write(" "+numbers.shift());
lessthan/scriptgreaterthan
This produces
zero one two
shift, unshift, push, and pop may be used on the same array. Queues are easily implemented using combinations.

106. How to create an object using JavaScript?
Objects can be created in many ways. One way is to create the object and add the fields directly.

lessthanscript type="text/javascript"greaterthan
var myMovie = new Object();
myMovie.title = "Aliens";
myMovie.director = "James Cameron";
document.write("movie: title is \""+myMovie.title+"\"");
lessthan
This produces
movie: title is "Aliens"
To create an object you write a method with the name of your object and invoke the method with "new".
lessthanscript type="text/javascript"greaterthan
function movie(title, director) {
this.title = title;
this.director = director;
}
var aliens = new movie("Aliens","Cameron");
document.write("aliens:"+aliens.toString());
lessthan/scriptgreaterthan
This produces
aliens:[object Object]

You can also use an abbreviated format for creating fields using a ":" to separate the name of the field from its value. This is equivalent to the above code using "this.".
lessthanscript type="text/javascript"greaterthan
function movie(title, director) {
title : title;
director : director;
}
var aliens = new movie("Aliens","Cameron");
document.write("aliens:"+aliens.toString());
lessthan/scriptgreaterthan
This produces
aliens:[object Object]

107. How to associate functions with objects using JavaScript?
Let's now create a custom "toString()" method for our movie object. We can embed the function directly in the object like this.

lessthanscript type="text/javascript"greaterthan
function movie(title, director) {
this.title = title;
this.director = director;
this.toString = function movieToString() {
return("title: "+this.title+" director: "+this.director);
}
}
var narnia = new movie("Narni","Andrew Adamson");
document.write(narnia.toString());
lessthan/scriptgreaterthan
This produces
title: Narni director: Andrew Adamson

Or we can use a previously defined function and assign it to a variable. Note that the name of the function is not followed by parenthisis, otherwise it would just execute the function and stuff the returned value into the variable.

lessthanscript type="text/javascript"greaterthan
function movieToString() {
return("title: "+this.title+" director: "+this.director);
}
function movie(title, director) {
this.title = title;
this.director = director;
this.toString = movieToString; //assign function to this method pointer
}
var aliens = new movie("Aliens","Cameron");
document.write(aliens.toString());
lessthan/scriptgreaterthan
This produces
title: Aliens director: Cameron

108. eval()?
The eval() method is incredibly powerful allowing you to execute snippets of code during exection.

lessthanscript type="text/javascript"greaterthan
var USA_Texas_Austin = "521,289";
document.write("Population is "+eval("USA_"+"Texas_"+"Austin"));
lessthan/scriptgreaterthan
This produces
Population is 521,289
(Continued on next part...)
109. What does break and continue statements do?
Continue statement continues the current loop (if label not specified) in a new iteration whereas break statement exits the current loop.

110. How to create a function using function constructor?
The following example illustrates this
It creates a function called square with argument x and returns x multiplied by itself.
var square = new Function ("x","return x*x");

111. What's Prototypes for JavaScript?
Objects have "prototypes" from which they may inherit fields and functions.

lessthanscript type="text/javascript"greaterthan
function movieToString() {
return("title: "+this.title+" director: "+this.director);
}
function movie(title, director) {
this.title = title;
this.director = director || "unknown"; //if null assign to "unknown"
this.toString = movieToString; //assign function to this method pointer
}
movie.prototype.isComedy = false; //add a field to the movie's prototype
var officeSpace = new movie("OfficeSpace");
var narnia = new movie("Narni","Andrew Adamson");
document.write(narnia.toString());
document.write("
Narnia a comedy? "+narnia.isComedy);
officeSpace.isComedy = true; //override the default just for this object
document.write("
Office Space a comedy? "+officeSpace.isComedy);
lessthan/scriptgreaterthan

112. unescape(), escape()
These are similar to the decodeURI() and encodeURI(), but escape() is used for only portions of a URI.

lessthanscript type="text/javascript"greaterthan
var myvalue = "Sir Walter Scott";
document.write("Original myvalue: "+myvalue);
document.write("lessthanbr /greaterthanescaped: "+escape(myvalue));
document.write("lessthanbr /greaterthanuri part: \"&author="+escape(myvalue)+"\"");
lessthan/scriptgreaterthan

If you use escape() for the whole URI... well bad things happen.
lessthanscript type="text/javascript"greaterthan
var uri = "http://www.google.com/search?q=sonofusion Taleyarkhan"
document.write("Original uri: "+uri);
document.write("
escaped: "+escape(uri));
v/scriptgreaterthan

113. decodeURI(), encodeURI()
Many characters cannot be sent in a URL, but must be converted to their hex encoding. These functions are used to convert an entire URI (a superset of URL) to and from a format that can be sent via a URI.
lessthanscript type="text/javascript"greaterthan
var uri = "http://www.google.com/search?q=sonofusion Taleyarkhan"
document.write("Original uri: "+uri);
document.write("lessthanbr /greaterthanencoded: "+encodeURI(uri));
lessthan/scriptgreaterthan
