您好我一直在开发应用程序，可以在图像上点击图像，您可以在任何地方添加图像上的图钉并存储其名称和详细信息。所有的工作都很好，我可以添加细节并保存，然后保存到数据库中。但是，如果你回到另一个链接，然后再回来。它显示旧的东西，而不是数据库中保存的东西。
我尝试重置和删除模型和集合，但它不起作用。还试图破坏模型，但它显示为错误
Object function (){ return parent.apply(this, arguments); } has no method 'reset'

我的第一反应是确认您在页面上没有2个相同的视图。我怀疑当您导航回页面时，原始视图仍然存在。因此，这个视图会在您更新的视图之前显示，这会让您认为它没有被更新。因此，请确认您希望看到的html没有显示在错误的位置。
另一方面，如果您从未看到正确的html（即使在第一次交互之后），那么我怀疑它与您的渲染逻辑有关。模型可能正在与服务器正确同步，但您没有从视图中侦听正确的事件;或者你正在听模型事件，但你的处理程序不会再次渲染视图。
