scope是html和单个controller之间的桥梁,数据绑定就靠他了。rootsope是各个controller中scope的桥梁。用rootscope定义的值,能够在各个controller中使用。下面用实例详细的说明一下。html
一、js代码this
phonecatApp.controller('TestCtrl',['$scope','$rootScope', function($scope,$rootScope) { $rootScope.name = 'this is test'; } ]); phonecatApp.controller('Test111Ctrl',['$scope','$rootScope', function($scope,$rootScope) { $scope.name = $rootScope.name; } ]);
二、htmlspa
<div ng-controller="TestCtrl"> I set the global variable.<strong>{{$root.name}}</strong> </div> <div ng-controller="Test111Ctrl"> 1,get global variable .<strong>{{name}}</strong><br> 2,get global variable .<strong>{{$root.name}}</strong> </div>
三、输出结果code
I set the global variable.this is test htm
1,get global variable .this is test get
2,get global variable .this is test io
四、总结:function
$rootScope.name设置的变量,在全部controller里面都是能够直接用{{$root.name}}来显示的,很强大。那固然也能够赋值给scope。class
