Question

I have a radiobuttonlist in my web application I have an event onclick for this it works fine in IE but not in some other browsers. The sample code is as follows:

<asp:RadioButtonList ID="rbgThreadStatus" runat="server" RepeatDirection="Horizontal"
        OnSelectedIndexChanged="rbgThreadStatus_SelectedIndexChanged" onclick="return rdblst_onClick();"
        AutoPostBack="True">
    <asp:ListItem Selected="True" Value="0">Alpha</asp:ListItem>
    <asp:ListItem Value="1">Bravo</asp:ListItem>
    <asp:ListItem Value="2">Charlie</asp:ListItem>
    <asp:ListItem Value="3">Delta Tickets</asp:ListItem>
    <asp:ListItem Value="4">Echo</asp:ListItem>
</asp:RadioButtonList>
<input type="hidden" value="0" id="hdnValue" runat="server" />

Following is the JavaScript:

function rdblst_onClick()
{
    var hdnValue = document.getElementById('ctl00_ctl00_MainMaster_ContentPlaceHolder2_hdnValue');    
    var length = document.getElementById('ctl00_ctl00_MainMaster_ContentPlaceHolder2_rbgThreadStatus').cells.length;
    for (var i = 0; i < length; i++) 
    {
        if (document.getElementById('ctl00_ctl00_MainMaster_ContentPlaceHolder2_rbgThreadStatus_' + i.toString()).checked) 
        {
            if (hdnValue.value != document.getElementById('ctl00_ctl00_MainMaster_ContentPlaceHolder2_rbgThreadStatus_' + i.toString()).value) 
            {
                hdnValue.value = document.getElementById('ctl00_ctl00_MainMaster_ContentPlaceHolder2_rbgThreadStatus_' + i.toString()).value;                
                //Some code here
            }                      
        }
    }
}
