进出口新的角度。

我有一个 NG-重复指令，我想存储答案之一属性全局变量。

I have a ng-repeat directive and I would like to store one of the answer attribute in a "global" variable.

<div ng-repeat="answer in answers">
    if(buffer != answer.discussion){
        //do something
        buffer = answer.discussionId;
    }    
</div>

I am sure there will be a hack to do this. But you should never do this in angular. Do it in your controller!
