var tags=document.getElementsByTagName('tagname');
for(var i=0;i<tags.length;i++){
  var dis=tags[i].getAttribute('display');
  if(dis='column'){
    //找到display:column标签，在这里添加事件或者其他
  }
}
为什么我打印tags的长度是0啊
贴上我的源码<form name="myForm" id="myForm" method="post" action="${ctx}/dwxx/dwxx_showAllDwxx.do">

我在2楼贴的源码，要怎么在js中，用ajax拿回的值，去改变<display:table>里面<display:column>所显示的值啊，或者怎么改变<display:table>这整个表格里所要展示的list集合。这个<display:column>标签的值不是用循环遍历出来的吧
