ng-repeat重复问题解决

当你在ng-repeat之后再使用一次会出现这样的报错
[ngRepeat:dupes] Duplicates in a repeater are not allowed.

  <div  ng-repeat="item in allComment">
      <div  ng-repeat = "src in item.photoSrc ">
           ![]({{src}})
      </div>
  </div>

解决办法 加上track by $index

  <div  ng-repeat="item in allComment">
      <div  ng-repeat = "src in item.photoSrc track by $index ">
            ![]({{src}})
      </div>
  </div>
