当td没有任何标示时，在jQuery中实现获取其在表格中的行和列：

<! DOCTYPE html PUBLIC " -//W3C//DTD XHTML 1.0 Transitional//EN " " http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd " >
< html xmlns = " http://www.w3.org/1999/xhtml " >
< head >
< meta http - equiv = " Content-Type " content = " text/html; charset=gb2312 " / >
< script language = " javascript " type = " text/javascript " src = " jquery-1.4.4.js " >< / script>
< script language = " javascript " >
    $(document).ready( function (){
        $( " #MyTable " ).find( " td " ).hover( function (){
            var hang = $( this ).parent().prevAll().length + 1 ;
            var lie = $( this ).prevAll().length + 1 ;
            $( " :input " ).val( " 第 " + hang + " 行，第 " + lie + " 列 " );
        })
    })
< / script>
< title > JQuery < / title>
< style type = " text/css " >
    table{
        background:#FFCC99;}
    td{
        text - align:center;
        width:100px;
        height:30px;}
< / style>
< / head>
< body >
< table id = " MyTable " border = " 1 " cellpadding = " 2 " cellspacing = " 0 " >
    < tr >
        < td > ( 1 ， 1 ) < / td>
        < td > ( 1 ， 2 ) < / td>
        < td > ( 1 ， 3 ) < / td>
    < / tr>
    < tr >
        < td > ( 2 ， 1 ) < / td>
        < td > ( 2 ， 2 ) < / td>
        < td > ( 2 ， 3 ) < / td>
    < / tr>
    < tr >
        < td > ( 3 ， 1 ) < / td>
        < td > ( 3 ， 2 ) < / td>
        < td > ( 3 ， 3 ) < / td>
    < / tr>
< / table>
< br / >
< input type = " text "   / >
< / body>
< / html>

其中所用到了prevAll，其含义是查找当前元素之前所有的同辈元素。如图所示：
