导读：为什么我不能绑定到第二个控制器内的控制器变量？ 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.states

为什么我不能绑定到第二个控制器内的控制器变量？

<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',function ($scope) {
    $scope.states2 = ["NY","WA"];
}]);

示例：https://jsfiddle.net/nukRe/135/

第二次ng-repeat不起作用.

当您使用控制器时,您应该在控制器中使用此关键字

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

Forked Fiddle

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
