考考大家jquery的基本功如何，关于选择器

HTML code

<!DOCTYPE html><html><head>    <title>Duplicate Cell</title>    <script src="http://ajax.aspnetcdn.com/ajax/jQuery/jquery-1.6.1.js"              type="text/javascript"></script>    <script type="text/javascript">        $(function () {            //数据            var data =            [                { No: "1", Name: "Jeffrey", Date: "2011/05/07", Score: 2011 },                { No: "1", Name: "Jeffrey", Date: "2011/06/21", Score: 9999 },                { No: "1", Name: "Jeffrey", Date: "2011/06/22", Score: 32767 },                { No: "2", Name: "Mulder", Date: "2011/06/01", Score: 999 },                { No: "3", Name: "Darkthread", Date: "2011/06/10", Score: 100 },                { No: "3", Name: "Darkthread", Date: "2011/06/15", Score: 100 }            ];            var h = [];            for (var i = 0; i < data.length; i++) {                h.push("<tr>");                var obj = data[i];                for (var p in obj)                    h.push("<td>" + obj[p] + "</td>");                h.push("</tr>");            }            $("#scoreboard tbody").html(h.join('\n'));            $("#btnShowMe").click(function () {              //在此添加代码                          })         });    </script>    <style type="text/css">        #scoreboard { width: 400px; margin-top: 20px; }        #scoreboard td { border: 1px solid gray; padding: 4px; }        #scoreboard thead { text-align: center; background-color: #ddd; }        #scoreboard tbody { text-align: center; }        td.c-Score { text-align: right; }    </style></head><body><input type="button" id="btnShowMe" value="test" /><table id="scoreboard">    <thead>        <tr><td>No</td><td>Name</td><td>Date</td><td>Score</td></tr>    </thead>    <tbody>    </tbody></table> </body></html>

我现在想要获取第二列Name的值，并将他逐个Alert出来，求代码

[解决办法]

JScript code

$("#btnShowMe").click(function () {              //在此添加代码              $('#scoreboard tbody tr').each(function(){                alert( $(this).find('td:eq(1)').html() )              })            })
[解决办法]
JScript code$("#btnShowMe").click(function () {  alert($(data).map(function () { return this.Name }).get().join());//直接操作数据  alert($('tbody tr td:nth-child(2)').map(function () { return this.innerHTML }).get().join());//操作DOM对象})
[解决办法]
再来种一方法~
JScript code$("#btnShowMe").click(function () {              //在此添加代码               $('#scoreboard tbody tr td').each(function(i){                if(i%4==1){                alert($(this).text());                }                              })            })
[解决办法]
$("#btnShowMe").click(function () {
alert( $('#scoreboard tbody tr td:eq(1)').length )  // 1
})


并非 td:eq(1) 的 arrayList
