JQUERY的效果在UpdatePanel中控件回发后失效的解决方案_.NET_编程开发_程序员俱乐部

我在UpdatePanel中用到了一个三级表单的效果，是用Jquery做的，但当我做这个ajax操作时就会失效

后来添加点JS代码就可解决

<asp:UpdatePanel ID="UpdatePanel2" runat="server" ChildrenAsTriggers="false" UpdateMode="Conditional">
            <ContentTemplate>
                
                <asp:RadioButtonList ID="_rbAddress" runat="server" AutoPostBack="true" 
                onselectedindexchanged="_rbAddress_SelectedIndexChanged1">
            </asp:RadioButtonList>
                <br />
                <asp:Panel ID="_panelAddress" runat="server">
            <table>
                    <tr><td>收货人姓名：</td><td>
                        <asp:TextBox ID="_txtConsignee" runat="server" MaxLength="25" onblur="checkRealName(this);"></asp:TextBox></td><td>
                        <asp:Label ID="lbl_RealName" runat="server" ForeColor="Red" EnableViewState="false"></asp:Label></td></tr>
                    <tr><td>邮政编码：</td><td>
                        <asp:TextBox ID="_txtPostcode" runat="server" onblur="checkInfo(this,'lbl_PostCode');" MaxLength="6"></asp:TextBox></td><td><asp:Label ID="lbl_PostCode" runat="server" ForeColor="Red" EnableViewState="false"></asp:Label></td></tr>
                    <tr><td>固定电话：</td><td>
                        <asp:TextBox ID="_txtTelNo" runat="server" onblur="checkInfo(this,'lbl_Phone');"></asp:TextBox></td><td><asp:Label ID="lbl_Phone" runat="server" ForeColor="Red" EnableViewState="false"></asp:Label></td></tr>
                    <tr><td>手机号码：</td><td>
                        <asp:TextBox ID="_txtMobile" runat="server" onblur="checkInfo(this,'lbl_Mobile');" MaxLength="11"></asp:TextBox></td><td><asp:Label ID="lbl_Mobile" runat="server" ForeColor="Red" EnableViewState="false"></asp:Label></td></tr>
                    <tr><td>地区：</td><td><div id="ChinaArea">
                   
                        <select id="province" name="province" style="width: 100px;"></select>
                        <select id="city" name="city" style="width: 100px;"></select>
                        <select id="county" name="county" style="width: 120px;"> </select>
                        <asp:Label ID="_lblPronice" runat="server" Text="上海市" style="display:none"></asp:Label>
                        <asp:Label ID="_lblCity" runat="server" Text="上海市" style="display:none"></asp:Label>
                        <asp:Label ID="_lblDiscount" runat="server" Text="黄浦区" style="display:none"></asp:Label>
                        <asp:HiddenField ID="Tprovince" runat="server" />
                        <asp:HiddenField ID="TCity" runat="server" />
                        <asp:HiddenField ID="TCounty" runat="server" />        
                    </div></td></tr>
                    <tr><td>街道小区：</td><td>
                        <asp:TextBox ID="_txtStreet" runat="server" 
                            onblur="checkInfo(this,'_lblStreet');" MaxLength="100" Width="100%"></asp:TextBox></td><td><asp:Label ID="_lblStreet" runat="server" ForeColor="Red" EnableViewState="false"></asp:Label></td></tr>
                    <tr><td></td><td>
                        <asp:Button ID="_btnAddressModify" runat="server" Text="修改地址" Visible="false" 
                            onclick="_btnAddressModify_Click"/>
                        <asp:Button ID="_btnAddress" runat="server" Text="添加地址" 
                            onclick="_btnAddress_Click" Visible="false"/>
                         </td></tr>
                  </table>
        </asp:Panel>
                <asp:UpdateProgress ID="UpdateProgress2" runat="server">
               <ProgressTemplate><font style="color:Red">正在处理中...</font></ProgressTemplate>
               </asp:UpdateProgress>
            </ContentTemplate>
            </asp:UpdatePanel>
             <script type="text/javascript">
                function reload() {
                Sys.WebForms.PageRequestManager.getInstance().add_endRequest(EndRequestHandler);
           }
           function EndRequestHandler() {
           $("#ChinaArea").jChinaArea({
           aspnet:true,
           s1:$("#_lblPronice").attr("innerHTML"),//默认选中的省名
           s2:$("#_lblCity").attr("innerHTML"),//默认选中的市名
           s3:$("#_lblDiscount").attr("innerHTML")//默认选中的县区名
           });
           }
             </script>

? 然后在<body onload="reload();">加入这句话就OK啦
