        <div>

          </div>

            <asp:Button ID="btnSavePersonalInfo" runat="server" Text="Save" Width="100px" Height="30px" CssClass="btn btn-primary" />
          </div>
        </div>
    </ContentTemplate>
</asp:UpdatePanel>
</pre>

我尝试过：



jquery代码：

What I have tried:

jquery Code:

$(document).ready(function () {
    $('#clonePersonalInfo').click(function () {
        $('div.personalInfo').after(function () {
            return $(this).clone();
        });
    });
});

推荐答案

（ document ）。ready （ function （）{

(document).ready(function () {

（' ＃clonePersonalInfo'）。click（ function （）{

('#clonePersonalInfo').click(function () {

（' div.personalInfo'）。after（ function （ ）{
return

('div.personalInfo').after(function () { return
