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
