问题描述
在angular2中，这些angular1事件的等效项是什么?
In angular2 what is the equivalent of these angular1 events?
$ routeChangeStart，$ routeChangeSuccess，$ routeChangeError
$routeChangeStart , $routeChangeSuccess ,$routeChangeError
我想在根应用程序组件中使用这些事件来处理任何路由更改.
I want to use these events in root app component to deal with any route changing.

如果我使用OnActivate，OnDeactivate事件，则需要将其添加到每个组件中:(
If i use OnActivate, OnDeactivate events, it needs to add it to every component :(
我也尝试实现自己的RouterOutlet，但是我无法访问先前关于激活，停用事件的指令，而且我也不知道如何处理路由更改错误
Also i tried to implement my own RouterOutlet but i can't access previous instruction on activate, deactivate events, also i don't know how to handle the route Change Error
也router.subscribe只给了我名字，但我想获取当前和下一个指令对象来更改某些属性
Also router.subscribe gave me the name only but i want to get the current and next instruction objects to change some properties
我的目标是:
1-在开始更改页面时显示加载指示器，并在页面加载时将其隐藏.
1- Show loading indicator when start change page and hide it on page load.
2-为当前和下一条指令制作过渡动画rtl或ltr
2- Make transition animation rtl or ltr for current and next instruction
推荐答案
有一些事件，例如 OnActivate ， OnDeactivate 和保护功能 CanActivate 和您可以查看的 CanDeactivate .
There are some events such as OnActivate, OnDeactivate and guard functions CanActivate and CanDeactivate that you can look at.
