推荐答案

据我所知，ng-click 仅适用于您的 $scope.所以你只能调用在你的 $scope 中定义的函数.要使用警报，您可以尝试访问 window 元素，只需使用 window.alert('Clicked').

As far as I know, ng-click works only within your $scope. So you would only be able to call functions, defined in your $scope itself. To use alert, you may try accessing the window element, just by using window.alert('Clicked').

EIDT:感谢易卜拉欣.我忘了.你不应该使用 window.alert，只要你不会定义:

EIDT: Thanks to Ibrahim. I forgot. You shouldn't be able to use window.alert, as far as you won't define:

$scope.alert = window.alert;

在这种情况下，在您的 ng-clicked 指令中使用 alert('Clicked') 应该可以工作.但最终，这种方法并不能解决您不触摸控制器的问题.

In this case, using alert('Clicked') in your ng-clicked directive should work. But at the end, this method would not solve your problem of not touching your controller.
