我在使用asp.net ajax的过程中结合使用了jquery 发现，开始没有问题，但是在页面中有UpdatePanel，UpdatePanel里提交后，jquery就失效了
为什么 大虾们？
具体的：
我的模板页：
<%@ Master Language="C#" AutoEventWireup="true" CodeFile="MasterPage.master.cs" Inherits="administrator_MasterPage" %>

然后子页：

<Triggers>
<asp:AsyncPostBackTrigger ControlID="btSearch" EventName="Click" />

</asp:UpdatePanel>

</asp:Content>
这样只要UpdatePanel中有操作，jquery 要执行的操作就失效！
<script type="text/javascript"> $(function() {
$("#checkallbottom").click(function() {
$("#tablelist tbody :checkbox").attr("checked", $(this).attr("checked"));
});
});
</script>
