</table>我现在需要将第四个属性user_head 转换为相应的图片，没有url的不显示就行。我的想法是对user_head这一属性进行判断，不空的进行操作，具体怎么实现，想不到。
需要怎么做，求帮助！
官方api或者demo是有定义的 你再去看看吧
我记得 在columnDefs函数中可以修改返回的值， 'target'指的是columns里的值得位置，'render'调用自己定会议的函数来重置返回值并返回。
下面是我之前许久的一段代码
var oTable1 = $('#table_job').dataTable({
language: {
"url":"<%=request.getContextPath()%>/static/json/Chinese.json"
},
ajax:{
type:"get",
url:"/search/applyRecords/${station.id}",
dataSrc:"data",
},
columns:[
{data:"userId"},
{data:"managerName"},
{data:"userName"},
{data:"type"},
{data:"createdTime"},
],
"columnDefs":[{
"render":function(data,type,row){
return getOpetionStatus(data);
},
"targets":3,
},
{
"render":function(data,type,row){
return getLocalTime(data);
},
"targets":4,
}
],
});
这样你应该可以操作你的数据了
写一个js判断 有值 就把值拼成<img src='url'> 没值 就返回空
周末两天休息，没上来看。周五的时候问题已经解决，在查看官网的时候找到了解决方案，就是用render 来定义返回值的。一楼是正解！
