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;
});

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)。

http://underscorejs.org/#find

具体地说，您可以退出forEach循环，并在任何位置抛出异常。

try {
   angular.forEach([1,2,3], function(num) {
      if (num === 2) throw Error();
   });
} catch(e) {
    // anything
}

但是，如果您使用其他库或实现自己的函数(在这种情况下是find函数)会更好，因此您的代码是最高级别的。

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
                  }
                });

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)
            }

        }      
    });
});

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
})
