JavaScript is an scripting language that is basically used for creating
interactive features on webpages. It can be used to create menus,
validate forms, swap images, or just about anything else you can think
of to do on a webpage. If you have ever taken a look at Google Maps or
Google's GMail service, you have an idea of what JavaScript is capable
of today. Whereas, ASP stands for Active Server Pages. ASP (Active
Server Pages) is an HTML pages that contain fixed scripts. ASP is a Microsoft
Technology. ASP is a program that runs inside IIS (Internet
Information Service).
In these tutorial, a regular HTML page with a small javascript code will
be created , and we will use this javascript code to include in the page
new information from a ".asp" file.
Example#1 :-
| javascript.html |
|
<html>
<title>My page</title>
<body>
<script language="javascript" src="javascript.asp"></script>
</body>
</html> |

| document.write ("hi") |

Further Exxplanation :-
- In the first file (javascript.html) we have include a javascript code
in , and within the code the file name from which we will get information
to complete our page (src: source). So that we are asking for information
to complete our page (javascript.html) to a different page (JavaScript.
asp). This time we have only include the file name, but we may use the
complete url even from a different site (for example: https://www.xyz.com/javascript.asp).
- In the second file (javascript.asp) we have include the information
necessary to write in the document the word "hi". This time
we have use ".asp" extensión for the second page even
though other extensions are possible.
Example#2 :-
It explains a very simple banner rotator system
Our page is "mypage.html" and we are requesting information
to complete it from "https://www.xyz.com/adrotator.asp" which
may be located in the same or in a different site. The information provided
by the second file will determinate the ad to be display in our page.
| mypage.html |
|
<html>
<title>My page</title>
<body>
<script language="javascript"
src="https://www.xyz.com/adrotator.asp"></script>
</body>
</html> |

document.write ("<IMG SCR=4.gif>")
document.write ("</A>")
<% case 5 %>
document.write ("<A HREF=https://www.xyz4.com">)
document.write ("<IMG SCR=4.gif>")
document.write ("</A>")
<% End select %> |

Further Explanation :-
- Lines 2-3. Each time a new visitor gets to
"http :// www .xyz .com / adrotator.asp" a new session will
be open, and by using the session method, we will define session("ad")
value to 0. In case the visitor is not new, the value for session("ad")
will exits, and that value will be keep.
- Lines 6-10. The value for Session("ad") is increased by
one unless that value is 5 (which is the maximum value allowed in this
script)
- Lines 13-34. By using Select_case the page will return the information
necessary to display the appropiate ad at "mypage.html". The
first time a visitor accesses our page the ad display will be the first
one, the second time ad number two and so on. After 5 visits, the process
will start again. We may easily increase the number of ads just by adding
more obtions within Select_case and setting the maximum number from
5 to the new maximum in line 6.
Note :- when writing the javascript code you must be very carefull:
do not include brakets within the brakets in the javascript code
p.e.: Correct: document.write ("<A HREF=https://www.xyz4.com">)
Incorrect: document.write ("<A HREF="https://www.xyz4.com"">)
Correct: document.write ("<A HREF='https://www.xyz4.com'">)
You may include in the response as many lines like the ones above or any
other javascript code.
