Hello Experts,
I have small problem while getting a selectedIndex of radio button list when is in Web Content Page.(.aspx created from Master page)
The following function GetSelectedIndex('rdlistone') works perfectly on simple .aspx page ,when passed a name of radiobuttonlist.
How I can execute following javascript sucessfully on web content page?
it gives error on var selectedIndex = GetSelectedIndex(oneElement.name);
var oneElement = document.getElementById("<%=rdoListRenew.ClientID %>");
var selectedIndex = GetSelectedIndex(oneElement.name);
function GetSelectedIndex(Name)
          var radioButtons = document.getElementsByName(Name);
          for (var x = 0; x < radioButtons.length; x++) 
            if (radioButtons[x].checked) 
                return x;
          return -1;
