我是一个角度新手使用多选择指令从isteven。
我写了一个test case，从根文件夹中的HTML可以很好地工作，但是当我将它合并到my app中时，没有一个下拉列表是可见的。
没有console.log错误消息。
我将HTML和控制器捆绑到同一个文件中。
“myApp.controller（'MainCtrl'，function（$scope，$http）”不会执行，尽管“var myApp=angular.module（”myApp“，[”isteven multi select“]）；”会执行。

注意，我之所以使用jQuery Ajax，是因为angular一直在JSON上插入内容，即使来自PHP interace指定的text/plain内容类型以及http调用指定的content type='text'

如果你认为我应该被否决，请帮助我理解我做错了什么，这样我就能从错误中吸取教训。
最佳答案
一。为什么不工作：
一个）。在您的测试用例中，您已经将<body data-ng-controller="MainCtrl">放在html中，这将调用MainCtrl函数。
（第二章）。在你的应用程序中，你也有一个MainCtrl，但是你既没有从html调用也没有$routeProvider.when
解决：
1）。最简单的方法：在你的应用中做<body data-ng-controller="MainCtrl">，和你的测试用例一样。
（第二章）。将MainCtrl中的代码放入enablersController中。如果需要，请在#/enablers页中选择输入模型。
两者都是猜测，如果有什么问题请告诉我。
