var qsParm = new Array();
function qs() {
 var query = window.location.search.substring(1);
 var parms = query.split(‘&’);
 for (var i=0; i<parms.length; i++) {
  var pos = parms[i].indexOf(‘=’);
  if (pos > 0) {
  var key = parms[i].substring(0,pos);
  var val = parms[i].substring(pos+1);
  qsParm[key] = val;
  }
 }
}example : if url is  www.yoursite.com/default.aspx?id=123&sessionid=swew2323od92891ks

Using the above code   alert(qsParm['id'] )  returns 123

If you ever want to call a javascript function (with or without  parameter) from a server side hyperlink control here it is..

Step 1 :

declare your javascript function between

Step 2:

<asp:HyperLink ID=”hypCate” runat=”server”

NavigateUrl=’<%# “javascript:showPopUp(” & DataBinder.Eval(Container.DataItem, “ID”) & “);” %>’

Text=’<%#DataBinder.Eval(Container.DataItem, “Name”)%>’ />

Carefully follow the single and double quotes for NavigateUrl attribute.

Needless to say showPopUp is the name of Javascript Function.

It displays the NAME as hyperlink. Clicking that calls javascript showPopUp.
