角JS休息的ForEach [英] Angular JS break ForEach

问题描述

我有一个角foreach循环，我想从回路断线，如果我一个值相匹配。下面code不起作用。

I have an angular foreach loop and i want to break from loop if i match a value. The following code does not work.

angular.forEach([0,1,2], function(count){
  if(count == 1){
    break;
  }
});

我怎样才能得到呢？

How can i get this?

推荐答案

有没有办法做到这一点。见<一href=\"https://github.com/angular/angular.js/issues/263\">https://github.com/angular/angular.js/issues/263.根据你正在做的，你可以使用一个布尔值，只是不会进入循环体的。是这样的：

There's no way to do this. See https://github.com/angular/angular.js/issues/263. Depending on what you're doing you can use a boolean to just not going into the body of the loop. Something like:

var keepGoing = true;
angular.forEach([0,1,2], function(count){
  if(keepGoing) {
    if(count == 1){
      keepGoing = false;
    }
  }
});
