AngularJS equal比较对象实例详解

使用情况

1 首先,所有满足 a === 3 这种的对象,在angular.equals(a,b)中都会返回真
2 所有对象的类型,以及属性值都相同的,也会返回真
3 NaN和NaN也会返回真(在javascript中,返回的是假)
4 正则也会返回真(在javascirpt,/abc/ /abc/被认为是不相等的)

样例

<html>
<head>
  <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
  <script src="http://apps.bdimg.com/libs/angular.js/1.2.16/angular.min.js"></script>
</head>
<body ng-app="myApp">
  <div ng-controller="myCtrl">
    {{ a_equals }}
    {{ user_equals }}
    {{ nan_equals }}
    {{ reg_equals }}
  </div>
  <script type="text/javascript">
  angular.module("myApp",[])
  .controller("myCtrl",function($scope){
    
    var a = 3;
    $scope.a_equals = angular.equals(a,3);//a === 3

    var user1 = {"name":"xing","age":30};
    var user2 = {"name":"xing","age":30};
    $scope.user_equals = angular.equals(user1,user2);

    $scope.nan_equals = angular.equals(NaN,NaN);//in javascirpt is false

    $scope.reg_equals = angular.equals(/abc/,/abc/);// in javascript is false
  });
  </script>
</body>
</html>

运行会得到四个true
