html code

<td class="center" ondblclick="ShowElement(this,&#39;intro&#39;)">{$vo.intro}</td>
<td class="center" ondblclick="ShowElement(this,&#39;address&#39;)">{$vo.address}</td>

js code

//双击修改
function ShowElement(element,abc){
 // console.log(abc);
 var list = abc;
 var me = element;
 var oldhtml = element.innerHTML;
 var newobj = document.createElement(&#39;input&#39;);
 newobj.type = &#39;text&#39;;//修改新创建的input的类型
 element.innerHTML = &#39;&#39;;//清空td中的内容用于存放新创建input;
 $(newobj).attr({ value:oldhtml});
 element.appendChild(newobj);//把input放入td
 //给input对象绑定鼠标移开事件
 newobj.onblur = function(){
  // 判断是否满足发送ajax的条件
  if(this.value != oldhtml){
   element.innerHTML = this.value;
   var value = this.value;
   // alert(value);
   //发送ajax请求
   var id = $(me).parents(&#39;.gradeA&#39;).find(&#39;.sid&#39;).html();
   var url = "{:U(&#39;Admin/Friend/onclick&#39;)}";
   var btn = $(this);

      url:url,
      data:{id:id,list:list,value:value},
      type:&#39;post&#39;,
