我制作了一个显示10个问题的测验代码。我希望在页面加载后立即加载该函数。在javascript中，它是onload，这里有角度我在控制器中定义后使用了angular.element(document).ready(function(){....});。它没有被加载。另外我想知道我的代码是否正确，我在控制器中使用ng-click提交，当我在javascript中执行程序时，它工作，不确定angularjs。另外请检查checkAnswer()功能中的foreach是否正确。如果有任何其他错误，请告诉我。

答案 0 :(得分：1)
正如@Arash所提到的，你正在以错误的方式编码angularjs。
如果你经历了一些角度开始的拳击手术会更好。
以下是工作angularjs代码
