edit：您已经澄清了错误的来源：它抛出错误是因为您告诉Angular removeCompany函数在名为AddController的控制器中。它不是——你已经在ListController中定义了它。

如果您已经提供了应用程序的完整代码，那么问题似乎是您说div元素应该使用一个名为AddController的控制器，但您还没有定义具有该名称的控制器。你需要另一个控制器来处理这一部分吗？看起来您在视图中引用的所有内容——companys、removeCompany等——都包含在ListController中。尝试删除提及AddController的部分，并使div元素看起来像这样：

<div class="col-xs-12 col-sm-12 col-md-4 col-lg-4">
