Question

I am using the following javascript to retrieve a value of a asp hidenfield.

var pagemode 
function setValue() {
pagemode= document.getElementById('<%#litTest.ClientID%>').value;
}

function Item_load(sender, eventArgs) {
 window.location.href = "Request.aspx?Request_ID=" + eventArgs.get_item().getMember('Request_ID').get_value() + "&ListType=" + pagemode;
} 

The value to the hiddenfield is loaded in page load in code behind. I need to pass the value as a querystring and it comes as undefined.

I would really appreciate if anyone can help.

Answer 1

So you don’t get a reference to your hiddenfield? Try this:

<script type="text/javascript">
  var litTestID = '<%= litTest.ClientID %>';

  function setValue() {
    var pagemode = $(litTestID).value;
    // ...
  }
</script>

Otherwise use the javascript debugger to inspect the order of executino and the variable values.
