AngularJS API之equal相比对象

动用状态

  • 1 首先,所有知足 a === 3
    这种的对象,在angular.equals(a,b)中都会回到真
  • 2 所有目标的类别,以及属性值都同一的,也会回去真
  • 3 NaN和NaN也会回来真(在javascript中,重临的是假)
  • 4 正则也会重返真(在javascirpt,/abc/ /abc/被认为是不等于的)

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>
