AngularJS从另一个控制器继承单个作用域

angularjs

AngularJS从另一个控制器继承单个作用域,angularjs,Angularjs,有没有办法通过$controller将单个作用域从一个控制器继承到另一个控制器这是我目前的代码： var peopleApp = angular.module('peopleApp', []); peopleApp.controller('indexController', function($scope){ $scope.sampleVar = "Hello World"; $scope.sampleVar2 = "Hello World Again"; }); peo

有没有办法通过$controller将单个作用域从一个控制器继承到另一个控制器

这是我目前的代码：

var peopleApp = angular.module('peopleApp', []); 

peopleApp.controller('indexController', function($scope){
    $scope.sampleVar = "Hello World";
    $scope.sampleVar2 = "Hello World Again";
});

peopleApp.controller('addController', function($scope, $controller){
    $controller('indexController', {$scope.sampleVar: $scope.sampleVar});
    alert($scope.sampleVar);
});

我知道这会抛出一个错误，因为“$controller（'indexController'，{$scope.sampleVar:$scope.sampleVar}”）；“应该是“$controller（'indexController'，{$scope:$scope}”）；”但是概念或所需的返回已经存在。

是否只继承1个值（$scope.sampleVar）从范围？应该是这样的：这不是一个好的设计

$controller（'indexController'，{$scope.sampleVar:$scope.sampleVar}）如果要在两个控制器之间共享单个属性，请创建一个服务。
<body ng-controller="parentController">
    <div ng-controller="childController1">
    </div>
   <div ng-controller="childController2">
    </div>
</body>

var app = angular.module('sample',[])
app.controller('controller1',function($rootScope,$scope){
$rootScope.parent ="I am visible in any controller";
})
app.controller('controller2',function($rootScope,$scope){
//here you can access rootScope property using rootScope or Scope 
// Because rootScope is parent for all scope object
// Angular scope protochain is like javascript protochain it looks from child to parent scope
   console.log( $rootScope.parent);
   console.log($scope.parent);
