How to run a ClientScript Containing a complex function

[Vistaar]

Hi Guys,

I m an engineering student working on web development project(in asp.net) and i am stuck up with the client side script. Precisly i want to run a complex function(which calculate the Hash of some txt) on client side and send the result back to the server. I have search the web a lot for help, but i could only find some scripts(useless to me) containing functions for poping up messages etc.

Please show me some way out to solve this problem, it will be greate if you give me some example of code showing such client scripts.

Thanks in advance.

If all you want to see is how to is send back a value to the server that is calculated on the client side then it would work like this.


<script type="text/javascript">

var someValueToSendBack = null;

// blah blah blah....
// Put your "complex function" here
// blah blah blah....

top.DisplayMenuFrame.location.href = '<<URL_OF_YOUR_SITE>>?paramterName='+someValueToSe ndBack;


</script>

hi dear
its so easy.
i know 3 ways for doing this job

1- use a form with hidden fields,which when your calculation finished then set the value of the hidden field with you HASH
[HTML]
<script language="javascript">
window.onload = function sendHashToServer()
{
oMyHashField = document.getElementById('myHash');
oFrmHash = document.getElementById('oFrmHash');

oMyHashField.value = calHash();

oFrmHash.submit();

}

function calHash()
{
var hashString;
// some steps
return hashString;
}
</script>
<form id="frmHash" action="somewhere.aspx">
<input name="myHash" id="myHash" value="" />
</form>
[/HTML]

2-you can use ajaxRequest with GET or POST method.

[HTML]
var ajaxRec = //you must create your request object based on your browser with XMLHttpRequest or activeXObject('Microsoft.XMLHttp')

//eg. hash = SSKDEWAASKDE232DSFD
ajaxRec.open('GET','somewhere.aspx?myHash=SSKDEWAA SKDE232DSFD',true);
ajaxRec.send(null);
[/HTML]
3-you can use iframes too.

regards.

Hey mohsenhosseini

Thnx for the reply. But what i want to know is dat like u have stated in the code an example called "calHash function" which calculates the hash value. In dat u specified "//some steps" which calculate the hash value. Now in .NET we have inbuilt functions & class libraries for calulating hash like MD5 and many more. So can i call these ready-made classes in this "calHash" function ?? What i m doubtful about is that, given the script is running on client side,will these classes be available always on client?

Note : .NET framework ( like JVM ) is installed on all the clients & not the SDK.

Well, if you really want those functions, you can use those functions from the server-side by making an XMLHttpRequest (i.e. Ajax). Create a page that just returns the hash value and use this in your script.
