Question

我在AngularJS中遇到此错误：

TypeError: Cannot call method 'apply' of undefined
    at Object.$get.e.$emit (http://localhost/TestPortal/js/lib/angular.min.js:87:296)
    at j (http://localhost/TestPortal/js/lib/angular.min.js:146:351)
    at http://localhost/TestPortal/js/lib/angular.min.js:88:100
    at Array.forEach (native)
    at m (http://localhost/TestPortal/js/lib/angular.min.js:6:193)

在我的控制器中调用这行代码时：

function ClientController($scope, $routeParams, $location, StaticData, Client, IndustryFactory) {
     $scope.$on('$viewContentLoaded', someMethod);
}

尝试下面也没有帮助，同样的错误：

ClientController.$inject = ['$scope', '$routeParams', '$location', 'StaticData', 'Client', 'IndustryFactory'];

Answer 1

您需要在控制器中明确包含$scope，以使其正常工作。

function ClientController($scope, $routeParams, $location, StaticData, Client, IndustryFactory) {
     $scope.$on('$viewContentLoaded', someMethod);
}


ClientController.$inject = ['$scope', '$routeParams', '$location'];

Answer 2

想出来。见修改后的代码：

$scope.$on('$viewContentLoaded', function() { someMethod() });

Answer 3

我认为这是缩小代码的问题。如@jayaram所描述的那样注入依赖关系，或者使用[]表示依赖关系并使用模块。请参阅Notes on Minification here
