如何在angularjs的控制器外部更改$ scope变量
[英]How to change a $scope variable outside the controller in angularjs
问题描述
I want to change a $scope.outsidescope outside the controller. 
我想在控制器外部更改$scope.outsidescope 。 I am using $routeProvider to route and change controller. 我正在使用$routeProvider来路由和更改控制器。 The $scope.outsidescope is present outside the ng-view . $scope.outsidescope位于ng-view 。
My Question is How can i change a $scope.value outside of the ng-view . 我的问题是如何在ng-view之外更改$scope.value 。
Sample Code: 样例代码：
<html ng-app="Myapp">
.......
<body>
<div>
{{outsidescope}}
</div>
<div class="" data-ng-view></div>
</body>
</html>
Angular Code: 角度代码：
var app = angular.module('Myapp', ['ngRoute']).
config(['$routeProvider', function($routeProvider) {
$routeProvider
.when("/", {templateUrl: "partials/home4.html", controller: "PageCtrl"})
.otherwise({
redirectTo: '/pages/404'
})
}]);
app.controller('PageCtrl', ['$cookies',function ($scope) {
$scope.outsidescope = 'Some thing.';
}

Use $rootScope instead of $scope to share data across the application. 使用$ rootScope而不是$ scope在整个应用程序中共享数据。 But creating a custom service is the best approach. 但是创建定制服务是最好的方法。

There are only two ways to share data between controllers 控制器之间只有两种共享数据的方法
1) Binding data in $rootScope 2) Binding data in services 1）绑定$ rootScope中的数据2）绑定服务中的数据

Its not Possible to change $scope outside the controller because it's not available outside the controller. 无法在控制器外部更改$ scope，因为在控制器外部不可用。
If you want to do so you can use parent scope which is $rootScope you can access this anywhere in your application. 如果要这样做，可以使用父范围$ rootScope，您可以在应用程序中的任何位置访问它。
But As per you requirement its better to use ng-bind instead of expression and in your router for every url you can call s resolve to assign the value to your this value. 但是根据您的要求，最好使用ng-bind代替expression，并且在路由器中为每个URL都可以调用s resolve来将值分配给this值。
