使用jQuery方便的统计Repeater列的总和

<script type="text/javascript">
$(function () {
StatSum("lblAAcount", "spAAcount");
StatSum("lblBBcount", "spBBcount");
}
function StatSum(lblId, spId) {
var sum = 0;
$("span[id$='" + lblId +"']").each(function () {
sum += parseInt($(this).text());
});
$("#" + spId).text(sum);
}
</script>
<asp:Repeater ID="rptTest" runat="server" >
<HeaderTemplate>
<table>
<tr>
<th>年度</th>
<th>AA总人数</th>
<th>BB总人数</th>
</tr>
</HeaderTemplate>
<ItemTemplate>

</ItemTemplate>
