出现错误 - “参数 'myCtrl' 不是函数，未定义”

Question

无法弄清楚我在哪里犯了错误。 在没有任何运气的情况下尝试了此操作- How to find a reason AngularJS "Argument 'MyCtrl' is not a function, got undefined"

这是我的 index.html 文件 -

Answer 1

该错误与应用程序的初始化方式和双 ng-app 有关。您可以通过手动引导 angularjs 轻松验证这一点：

当您同时删除ng-app 并在controllers/controller.js 的底部添加以下sn-p 时，您的脚本可以工作：

angular.element(document).ready(function() { angular.bootstrap(document, ['myApp']); });

Answer 2

控制器构造函数必须传入数组

app.controller('myCtrl', ['$scope', function($scope) { //your controller code here } ]);
