javascript关于table的问题
现在我有个动态生成的table,每个单元格里面是一个数字,每个数字都是个超连接. 
 现在我点击数字,能不能得到这个数字的行和列的索引,在页面下放显示出来? 
 重点是怎么得到行和列的索引,请高手指点.
------解决方案--------------------cellIndex和rowIndex属性

  <head>    
  <script language=javascript>  
 	function a(o){ 
 		var col=o.parentNode.id; 
 		var row=o.parentNode.parentNode.id; 
 		alert( "col: "+col+ ";row: "+row); 
 	} 
  </script>  
  </head>  
  <body>  
  <table border=1 width= "100 ">  
 	 <tr id= "1 ">  <td id= "1 " >  <a href= "# " onclick= "a(this) "> 1 </a>  </td>  <td id= "2 ">  <a href= "# " onclick= "a(this) "> 2 </a>  </td>  </tr>  
 	 <tr id= "2 ">  <td id= "1 ">  <a href= "# " onclick= "a(this) "> 3 </a>  </td>  <td id= "2 ">  <a href= "# " onclick= "a(this) "> 4 </a>  </td>  </tr>

  <head>  
  <title> new page </title>  
  <script language=javascript>  
 function a(obj){ 
 var col=obj.parentNode.cellIndex;//列索引,初始值为0 
 var row=obj.parentNode.parentNode.rowIndex;//行索引,初始值为0 
 alert( "col: "+col+ ";row: "+row); 
 } 
  </script>
