// add method
$(document).ready(function(){

var $table=$("#tab tr");
var len=$table.length;
// alert(" content :"+"<trid="+(len+1)+"><td align=\'center\'>"+len+"</td><tdalign=\'center\'>jQuery"+len+"</td><tdalign=\'center\'><a href=\'#\'onclick=\'deltr("+(len+1)+")\'>删除</a></td></tr>");

for(var temp=index+1;temp<=$table.length;temp++)
{

}
}
</script>
</head>
<body>
<br/>
<table id="tab" border="1" width="60%" align="center">
<tr>
<td width="20%" align="center">序号</td>
<td align="center">标题</td>
<td align="center">操作</td>

<br/>
<div style="border:2px; border-color:#00CC00; margin-left:20%">
<input type="button" id="but" value="add"/>
</div>
