Heya, Preeti.

Here's where your problem lies:
[code=javascript]
'Winner.aspx?Em pNomId='++;
[/code]

This code attempts to increment the value of 'Winner.aspx?Em pNomId=' by 1 and then save then new value to itself, which is just wrong on so many levels.

P.S., Changed thread title to better describe the problem (did you know that thread titles that do not follow the Posting Guidelines actually get FEWER responses?).

thanks for replying .but i need that id because based on that id i am try to update the database do i need a server side code for that please help me i feel really stuck in there

Heya, Preeti.

The problem is not the 'Winner.aspx?Em pNomId=' part. The problem is the '++;' part.

Did you mean this instead:
[code=javascript]
window.location = 'Winner.aspx?Em pNomId=' + employeenominat ionid;
[/code]

thanks for helping me out but now i want that id in the url how i can get that id in the url please tell

[pbmods]

Heya, Preeti.

To put the id in the URL, you'd simply do this:
[code=javascript]
window.location = 'Winner.aspx?Em pNomId=' + employeenominat ionid;
[/code]

Which is different from what you were trying to do previously:
[code=javascript]
window.location = 'Winner.aspx?Em pNomId='++;empl oyeenominationi d;
[/code]

yes sir as you said i made a change in the code my code is now look like this

<script type="text/javascript">
 function disp_confirm(employeenominationid)
  {

  
  var r=confirm('Are you sure ?:'+employeenominationid)
   if (r==true)
    {
  
window.location ='Winner.aspx?EmpNomId=' + employeenominationid;
 document.Form1.submit()
      }
  else
    {
  
    //document.write("You pressed Cancel!")
    }
  }
  
		</script>

and server side code i am call a qurey string like this

			string EomNomid;
			EomNomid = Request.QueryString["employeenominationid"];

[pbmods]

Heya, Preeti.

Close.

Your server-side code doesn't talk with JavaScript that way, so instead of using the name of the JavaScript variable, you need to use the name that you put in the URL:

[code=asp]
string EomNomid;
EomNomid = Request.QuerySt ring["EmpNomId"];
[/code]
