angularjs - 在 AngularJS 中的另一个 Controller 中使用 Controller

Question

为什么我无法绑定(bind)到第二个 Controller 内的 Controller 变量？

<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"];
}]);

第二次 ng-repeat 不起作用。

Answer 1

当您使用controllerAs时，您应该在 Controller 中使用this关键字

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

注意

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
