angular2 - 使用路由器发出问题

首先,我是使用nodejs,angular2和typescript进行此类编程的完全初学者.基本上我开始阅读https://angular.io/docs/ts/latest/guide/forms.html和https://angular.io/docs/ts/latest/guide/router.html#!#base-href使用新页面扩展我的应用程序.我使用mdl在我的应用程序上使用材质组件.
角度2似乎手动重新加载和路由不同所以我得到以下问题:

我尝试了解发生了什么,有人可以解释我在angular2中重新加载和路由之间的区别,以及我如何适应路由到重新加载行为的处理？

如果不查看源代码，就很难发现问题。

重新加载页面和使用路由器之间的简化区别是：

路由器将在标签内渲染路由。这允许您动态加载页面中的组件，而无需重新加载任何页面。
重新加载页面会导致整个页面被重新加载，如果使用 AoT 编译，则成本要高得多。实际上不需要重新加载，所有导航都应该在路由器中处理。

至于您的问题，看起来您正在多次加载该组件。如果您谈论的是与工具提示重叠的文本，则可能是导入材料设计组件的方式存在依赖性问题。发布您的代码，我会尽力帮助您。
