helo,
i want to select all checkboxes by using javascript my code is as follows

 <script language ="javascript" type="text/javascript">
     function checkbox1(chcontrol, state)
    {
    var chkbx1=document.getElementById(chcontrol);
    var chkBoxCount=chkbx1.getElementsByTagName("input");
     for(var i=0;i<chkBoxCount.length;i++)
        {
            chkBoxCount[i].checked = state;
        }
       return false; 
    }
    </script>

 select<a id="chk1" href="#" onclick="javascript:checkbox1('<%=CheckBoxList1.ClientID%>', true)">All</a>|<a id="chk2" href="#" onclick="javascript:checkbox1('<%=CheckBoxList1.ClientID%>', false)">None</a>

this code is working fine with anchor tags when i call my function from this tag,
but it is not working when i call the javascript function from checkbox like in this way <asp:CheckBox ID="CheckBox1" runat="server" Text="Select All" oncheckedchanged="javascript:checkbox1('<%=CheckBoxList1.ClientID%>', true)" /><br />

please help
