I cannot use jQuery.

added code for without jQuery.

I am not a JS guru. But, why do I want to add so much code? I just want to populate a variable in JS after page_load has finished processing on server side. Isn't there any simple way out ?

Angshuman 2010-10-25 09:51:12

due to different browsers, ie, FF and so on...you could try window.onload.

Answer 2

A:

Is your postback done with ajax?

If so then only part of the page is refreshed and the script is not executed again.

You can wrap it in a function and add that function to the postback callback handler.

This is how I did it on one site:

Sys.WebForms.PageRequestManager.getInstance().add_endRequest(function () { edit.update(); });

There is no AJAX. The page is made up of standard ASP.Net Server Controls with plain JS.

Answer 3

A:

Putting some Javascript after a <FORM> element does not mean it will get processed after the form has been submitted. It gets processed as the HTML is rendered, which is what you are seeing.

If you want to run some Javascript after POSTing a form then you need to use a onClick handler, something like this:

<FORM NAME="myform" ACTION="" METHOD="GET">
<INPUT TYPE="text" NAME="inputbox" VALUE=""><P>
<INPUT TYPE="button" NAME="button" Value="Click" onClick="dosomejavascriptstuff()">
</FORM>

Steve Claridge 2010-10-25 09:44:26

But, that is not my requirement. I want the JavaScript variable to be populated after the page_load on server side has finished processing.

Answer 4

A:

Hi All, Thanks for your replies. I got closer to the issue but I do not know the solution :( The C# variable contains a path info as "D:\" and when I set this on a JS variable I get the error as "Unterminated String Constant". How do I overcome this.

Actually this was the problem, why the script was not getting executed. As soon as I removed the "\", it worked !

Angshuman 2010-10-25 10:20:43

\ needs to be escaped in js strings as \\ otherwise it escapes the ending ". "D:\" should be "D:\\"
