角。在条件匹配的情况下，forEach循环不能中断。

我个人的建议是使用NATIVE FOR循环而不是angular.forEach。

NATIVE FOR循环比其他FOR循环快90%左右。

在ANGULAR中使用FOR循环:

var numbers = [0, 1, 2, 3, 4, 5];

for (var i = 0, len = numbers.length; i < len; i++) {
  if (numbers[i] === 1) {
    console.log('Loop is going to break.'); 
    break;
  }
  console.log('Loop will continue.');
}

$scope.arr = [0, 1, 2];  
$scope.dict = {}
for ( var i=0; i < $scope.arr.length; i++ ) {
    if ( $scope.arr[i] == 1 ) {
        $scope.exists = 'yes, 1 exists';
        break;
    }
 }
 if ( $scope.exists ) {
     angular.forEach ( $scope.arr, function ( value, index ) {
                      $scope.dict[index] = value;
     });
 }

这是不可能的。见https://github.com/angular/angular.js/issues/263。取决于你在做什么，你可以使用布尔值来不进入循环体。喜欢的东西:

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

试试这个作为休息;

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

var ary = ["JavaScript", "Java", "CoffeeScript", "TypeScript"];
var keepGoing = true;
ary.forEach(function(value, index, _ary) {
    console.log(index)
    keepGoing = true;
    ary.forEach(function(value, index, _ary) {
        if(keepGoing){ 
            if(index==2){
                keepGoing=false;
            }
            else{
                console.log(value)
            }

        }      
    });
});
