check and uncheck the checkbox in repeater control using javascript?

Question

how to check and uncheck the checkbox in repeater control using javascript? here i m unable to check the checkbox in single click or uncheck the checkbox in single check.

my code is:

 <asp:Repeater id="repeaterentry" runat="server"  >
<HeaderTemplate>
<table border="1" width="100%">
<tr>
<th style="width:10px" align="left"><asp:CheckBox ID="allCheckbox1"   runat="server" /></th>
<th><asp:LinkButton ID="lnkbtn1" runat="server" CommandName="UserName">Name</asp:LinkButton></th>
<th>Password</th>
</tr>
</HeaderTemplate>
<ItemTemplate>
<tr>
<td style="width:10px"><asp:CheckBox ID="chkContainer" runat="server" /></td>
<td><%#Eval("uname") %> </td>
<td><%#Eval("upass")%> </td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>

the jquery :

<script type="text/jscript" language="jscript">
window.onload = function () {
      var $allCheckbox = $('<%= this.repeaterentry.ClientID %>'); // you could use a class here either - depends on you having access to '<%= this.allCheckbox.ClientID %>'
$allCheckbox.change(function () {
    var $table = $allCheckbox.closest('table');
    var $checkboxes = $(':checkbox', $table).not($allCheckbox); // this selector is a bit evil, if you have other checkboxes in the table as well ...
    if ($allCheckbox.is(':checked')) {
        $checkboxes.attr('checked', 'checked');
    }
    else {
        $checkboxes.removeAttr('checked');
    }
});
        }
    }
</script>
