我更喜欢用return来做。将循环部分放在私有函数中，并在想要打破循环时返回。

我会用return代替break。

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

效果非常好。

请使用ForEach的一些或所有实例，

Array.prototype.some:
some is much the same as forEach but it break when the callback returns true

Array.prototype.every:
every is almost identical to some except it's expecting false to break the loop.

例如:

var ary = ["JavaScript", "Java", "CoffeeScript", "TypeScript"];

ary.some(function (value, index, _ary) {
    console.log(index + ": " + value);
    return value === "JavaScript";
});

每个的例子:

var ary = ["JavaScript", "Java", "CoffeeScript", "TypeScript"];

ary.every(function(value, index, _ary) {
    console.log(index + ": " + value);
    return value.indexOf("Script") > -1;
});

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;
  }
});

据我所知，Angular并没有提供这样的函数。你可能想要为此使用下划线的find()函数(它基本上是一个forEach，一旦函数返回true就会跳出循环)。
