如何获取当前的routeName？ [英] How to get current routeName?

问题描述

假设我的应用程序绑定到 window.App ：
我可以得到它的路由器与 App .__ container __。lookup（router ：主）。

如何访问当前路由？具体来说，我想获得它的属性 routeName 。

解决方案

它存在属性称为 currentPath ，它是应用程序当前状态的计算别名。要得到当前 routeName 这是同样的事情，你可以这样做：

  App = Ember，Application.create（{
 currentPath：''
}）; 
 
 ApplicationController：Ember.Controller.extend（{
 currentPathDidChange：function（）{
 App.set（'currentPath'，this.get（'currentPath'））; 
} .observes（'currentPath'）
}）; 
  

然后从以下任何地方访问：

  App.get（ 'currentPath'）; 
  

请参阅 here 了解更多有关 currentPath property。

另外值得一提的是，您可以启用标志 LOG_TRANSITIONS 每次应用程序更改状态/路由时，当前路由名称都记录在浏览器控制台中：

  App = Ember.Application.create {
 LOG_TRANSITION：true 
}）; 
  

注意
使用此应用.__容器__。lookup（router：main）仅用于调试目的，因为它是一个内部API。

希望它有帮助。 >

Assuming my application in bound to window.App: I can get it's router with App.__container__.lookup("router:main").

How can I access current route? Specifically I want to get its property routeName.

解决方案

It exist a property called currentPath which is a computed alias for the current state of the application. To get the current routeName which is the same thing you could do something like this:

App = Ember,Application.create({
  currentPath: ''
});

ApplicationController : Ember.Controller.extend({
  currentPathDidChange: function() {
    App.set('currentPath', this.get('currentPath'));
  }.observes('currentPath')
});

and then access it from anywhere with:

App.get('currentPath');

See here for more info for the currentPath property.

Also worth mentioning is that you can enable the flag LOG_TRANSITIONS to true to have the current route name logged in your browser console every time the application changes state/route:

App = Ember.Application.create({
  LOG_TRANSITION: true
});

Note Use this App.__container__.lookup("router:main") only for debugging purposes since it's an internal API.

Hope it helps.
