在AngularJS中的另一个控制器中使用控制器 [英] Using controller inside another controller in AngularJS

问题描述

为什么我不能在第二个控制器内绑定到控制器的变量?

Why I can't bind to controller's variable inside second controller?

<div ng-app="ManagerApp">
    <div ng-controller="MainCtrl">
        Main: 
        <div ng-repeat="state in states">
            {{state}}
        </div>
        <div ng-controller="InsideCtrl as inside">
            Inside:
            <div ng-repeat="state in inside.states2">
                {{state}}
            </div>
        </div>
    </div>
</div>

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

angularApp.controller('MainCtrl', ['$scope', function ($scope) {
    $scope.states = ["NY", "CA", "WA"];
}]);

angularApp.controller('InsideCtrl', ['$scope', function ($scope) {
    $scope.states2 = ["NY", "CA", "WA"];
}]);

第二个ng-repeat无效.

Second ng-repeat doesn't work.

推荐答案

在使用controllerAs时，应在控制器中使用this关键字

As you are using controllerAs you should be using this keyword in controller

angularApp.controller('InsideCtrl', [ function() {
    var vm = this;
    vm.states2 = ["NY", "CA", "WA"];
}]);

注意

从技术上讲，您应该一次遵循一种方法.不要混淆 这两个模式一起使用controllerAs语法/Normal 控制器声明，就像您使用$scope

Technically you should follow one approach at a time. Don't mix up this two pattern together, Either use controllerAs syntax/ Normal controller declaration as you did for MainCtrl using $scope
