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)
            }

        }      
    });
});

试试这个作为休息;

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

break在angular forEach中是不可能实现的，我们需要修改forEach来实现。

$scope.myuser = [{name: "Ravi"}, {name: "Bhushan"}, {name: "Thakur"}];  
                angular.forEach($scope.myuser, function(name){
                  if(name == "Bhushan") {
                    alert(name);
                    return forEach.break(); 
                    //break() is a function that returns an immutable object,e.g. an empty string
                  }
                });

正如其他答案所说，Angular不提供这个功能。而jQuery可以，如果你已经加载了jQuery和Angular，你就可以使用它

jQuery.each ( array, function ( index, value) {
    if(condition) return false; // this will cause a break in the iteration
})

参见http://api.jquery.com/jquery.each/

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;
    }
  }
});

使用Array Some方法

 var exists = [0,1,2].some(function(count){
      return count == 1
 });

Exists将返回true，您可以将其用作函数中的变量

if(exists){
    console.log('this is true!')
}
