scope是html和單個controller之間的橋樑,數據綁定就靠他了。rootsope是各個controller中scope的橋樑。用rootscope定義的值,能夠在各個controller中使用。下面用實例詳細的說明一下。html
一、js代碼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、輸出結果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、總結:function
$rootScope.name設置的變量,在全部controller裏面都是能夠直接用{{$root.name}}來顯示的,很強大。那固然也能夠賦值給scope。class
