jquery怎么获取不到tr的id呢？每次都是undefine

Question

<form id="form1" runat="server">
<div style=" border:1px solid #f00;">
    <table id="table1">
        <tr id="tr1">
            <td>字段名</td>
            <td>字段类型</td>
            <td>字段大小</td>
            <td>控件类型</td>
            <td>表名</td>
        </tr>
        <tr id="trFormatStr_1" onclick="fnTrClick()" runat="server">
            <td id="td1"><asp:TextBox ID="tbxStrName" runat="server" Text=''></asp:TextBox></td>
            <td id="td2"><asp:TextBox ID="tbxStrType" runat="server" Text=''></asp:TextBox></td>
            <td id="td3"><asp:TextBox ID="tbxStrSize" runat="server" Text=''></asp:TextBox></td>
            <td id="td4">
                <asp:DropDownList ID="ddlControlType" runat="server">
                </asp:DropDownList>
            </td>
            <td id="td5"><asp:TextBox ID="TextBox1" runat="server" Text=''></asp:TextBox></td>
        </tr>
    </table>
</div>
</form>

$(function () { // $("#trFormatStr_1").click(function () { // alert(1); // }); }); function fnTrClick() { alert($(this).attr("id")); alert(2); }

运行起来，id没变的，可看图片

可以尝试下$("#trFormatStr_1")[0]
