本人用ajax做一个显示新闻列表的页面，代码：

 $(function() {  

         //调用下面的方法　              

})

  var tbody = "";
            $.ajax({
                type: "POST",
                dataType: "json",
                url: "NewsList.ashx",
                data: "pageindex=" + (pageIndex+1),
                success: function(json) {
                    $("#productTable tr:gt(0)").remove();
                    $.each(json, function(i, n) {
                        var trs = "";
                        trs += "<tr><td style='text-align:center'><a href=\"#\" class=\"info2\">" + n.Title +
                                                   "</a></td><td style='text-align:center'>" + n.ReadTimes +
                                                   "</td><td style='text-align:center'>" + n.time + "</td></tr>";
                        tbody += trs;
                    });
                    $("#productTable").append(tbody);
                    //奇偶行颜色不同
                    $("#productTable tr:gt(0):odd").attr("class", "odd");
                    $("#productTable tr:gt(0):even").attr("class", "enen");
                }
            });

实现鼠标移到新闻的标题上显示层，移开层隐藏层。代码：

 $("#productTable td a").mousemove(function(e) {
                $("#content").css("left", e.pageX).css("top", e.pageY).show(100);
            });
            $("#content").mouseout(function() {
                $("#content").hide();
            });

新闻列表有显示结果，但$("#productTable td a")获取不了a元素，而且查看源文件ajax生成的html都看不见？
