# Angularjs中scope與rootscope區別及聯系 scope是html和單個controller之間的橋梁，數據綁定就靠他了。rootscope是各個controller中scope的橋梁。用rootscope定義的值，可以在各個controller中使用。下面用實例詳細的說明一下。 1.js代碼 ~~~ phonecatApp.controller('TestCtrl',['$scope','$rootScope', function($scope,$rootScope) { $rootScope.name = 'this is test'; } ]); phonecatApp.controller('Test111Ctrl',['$scope','$rootScope', function($scope,$rootScope) { $scope.name = $rootScope.name; } ]); ~~~ 2.html代碼 ~~~ <div ng-controller="TestCtrl"> I set the global variable.<strong>{{$root.name}}</strong> </div> <div ng-controller="Test111Ctrl"> 1,get global variable .<strong>{{name}}</strong><br> 2,get global variable .<strong>{{$root.name}}</strong> </div> ~~~ 3.顯示結果 I?set?the?global?variable.this?is?test?? 1,get?global?variable?.this?is?test?? 2,get?global?variable?.this?is?test?? 由結果可以看出來，$rootScope.name設置的變量，在所有controller里面都是可以直接用{{$root.name}}來顯示的，很強大。那當然也可以賦值給scope.
