使用 Jquery 高亮

Question

我在试图让这个 Jquery 突出显示在我当前的项目中工作时遇到了麻烦，我有一个文本框，当用户单击按钮时，我在 HTML 表中输入他们想要的手机号码我是 Jquery突出显示以启动并突出显示与用户输入的条件匹配的所有手机号码，但由于某种原因，它似乎不起作用也不会引发错误？！？！有人能帮助我吗。

 $('#<%= BtnFindMobile.ClientID %>').click(function () {
            var phonenumber = $('#<%= txtSearchMobile.ClientID %>').val();
            $('#grdvHandSets td.highlight').removeClass('highlight'). // Clear existing highlights
            // Find matching phonenumber fields
            find('input.phonenumber').filter(function () {
            return $(this).val() == phonenumber;
            }).
            closest('td').addClass('highlight'); // And highlight these cells
            return false;
         });

这里是html表和它的第二个TD，我想引用手机列“txtMobileNumber”，高光的CSS设置为背景色：红色；

 <span class="AddressLabel">Search Mobile:</span><asp:TextBox ID="txtSearchMobile"
                                  runat="server" MaxLength="11" Style="width: 90px !important"></asp:TextBox>&nbsp;&nbsp
                              <asp:Button ID="BtnFindMobile" runat="server" Text="Find" /></p>


<table cellspacing="0" id="grdvHandSets" style="border-collapse:collapse;">

试试这个：

$('#<%= BtnFindMobile.ClientID %>').click(function () {
            var phonenumber = $('#<%= txtSearchMobile.ClientID %>').val();
            $('#grdvHandSets td.highlight').removeClass('highlight'); // Clear existing highlights
            // Find matching phonenumber fields
            $('#grdvHandSets td input.phonenumber').filter(function () {
            return $(this).val() == phonenumber;
            }).
            closest('td').addClass('highlight'); // And highlight these cells
            return false;
         });
