JQuery的克隆问题

Question

今天使用JQuery克隆Dev控件，结果报错说输入字符串的格式不正确。HTML代码如下：  <tr align="center" id="trclone">
                <td>
                    <dx:ASPxDateEdit ID="dtStart" runat="server">
                        <CalendarProperties TodayButtonText="今天" ClearButtonText="清除">
                        </CalendarProperties>
                    </dx:ASPxDateEdit>
                </td>
                <td>
                    <dx:ASPxDateEdit ID="dtEnd" runat="server">
                        <CalendarProperties TodayButtonText="今天" ClearButtonText="清除">
                        </CalendarProperties>
                    </dx:ASPxDateEdit>
                </td>
                <td>
                    <asp:TextBox ID="txtSchool" runat="server"></asp:TextBox>
                </td>
                <td>
                    <asp:TextBox ID="txtContent" runat="server"></asp:TextBox>
                </td>
            </tr><asp:LinkButton ID="lkAddRange" runat="server" Text="增加"></asp:LinkButton>//此句为按钮JS代码如下：<script type="text/javascript">
    $(document).ready(function() {
        $("#lkAddRange").click(function() {
        var trclone = $("#trclone").clone();
            $("#tbclone").append(trclone);
        });
    });
</script>

Answer 1

$("#tbclone").append(trclone);
在这里设个断点调试一下看看trclone对象详细

Answer 2

$("#tbclone").append(trclone);
改成
$("#tbclone").append(trclone.html());

Answer 3

<script type="text/javascript">
    $(document).ready(function() {
        $("#lkAddRange").click(function() {
            $("#tbclone").append($("#trclone").html());
        });
    });
</script>

Answer 4

你确认是 ....clone() 这行报错吗
