在角JS 2 $范围数组的区别 [英] Difference of two $scope array in angular js

问题描述

有没有办法返回在angularjs

Is there a way to return the difference between two array present in a scope in angularjs

例如，

 $scope.user1 = ['a', 'b'];
 $scope.user2 = ['a', 'b', 'c', 'd'];

这两个差异应该给我的另一个作为
 $ scope.user3 = ['C'，'D']

Difference of these two should give me an another as $scope.user3= ['c','d']

推荐答案

Underscore.js有差异的方法这一点。

Underscore.js has the difference method for this.

http://underscorejs.org/#difference

$scope.user1 = ['a', 'b'];
$scope.user2 = ['a', 'b', 'c', 'd'];
$scope.user3 = _.difference($scope.user2, $scope.user1);
