Get current route name in Ember

问题:

I need to get the current route name in my ember application; I tried this: Ember App.Router.router.currentState undefined but it doesn't work for me (there is probablig something i'm missimg...) I use Ember rc6 and I have a multilingual app; in the applicationRoute I detect the browser's language and I redirect to the correct page with:

this.transitionTo(userLang);

but I would like this to be executed only when user are on the home page, so something like this:

if (currentRoute == 'home'){
  this.transitionTo(userLang)
}

回答1:

You could observe the application's currentPath and set it to the current route accordingly when it changes:

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

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

This way you have access to the currentPath when ever you want with App.get('currentPath');

E.g.

if (App.get('currentPath') == 'home'){
  this.transitionTo(userLang);
}

Hope it helps.

This worked for me on 1.3.0-beta (and a quick glance at the source for 1.1.2 suggests it would work there too):

App.__container__.lookup('router:main').location.lastSetURL

Note that the documentation states:

At present, it relies on a hashchange event existing in the browser.

However, I believe it's strongly suggested that App.__container__ not be used in production code. A more acceptable alternative would be to use App.Router.router.currentHandlerInfos, which provides information on the current Ember route.

Yet another option is currentRouteName on the ApplicationController. You can add needs: ['application'] to your controller, then access the route name with controllers.application.currentRouteName. This will return something like posts.index.

With the shift to components, it is harder to get route name. The best way is to add an initializer such as

ember g initializer router

(from command line), and

export function initialize(application) {
  application.inject('route', 'router', 'router:main');
  application.inject('component', 'router', 'router:main');
}

export default {
  name: 'router',
  initialize
};

in a initializers/router.js. You can also inject into controller if you need to. Then just do simply

this.get('router.currentRouteName');

in JS, or

{{router.currentRouteName}}

in template.

This is the only way I have found to get it reliably, and observable in Ember 2.4

If you want to get current route in your component or controller you can inject routing service (routing: Ember.inject.service('-routing'))

(for more) and use:

this.get('routing.currentRouteName') or this.get('routing.currentPath')

Example with component and computed property:

import Ember from 'ember';

export default Ember.Component.extend({
  routing: Ember.inject.service('-routing'),

  checkMyRouteName: Ember.computed(function() {
    return this.get('routing.currentRouteName');
  })
})

Example with controller and computed property:

import Ember from 'ember';

export default Ember.Controller.extend({
  routing: Ember.inject.service('-routing'),

  checkMyRouteName: Ember.computed(function() {
    return this.get('routing.currentRouteName');
  })
})

Current route in your route you just need this.routeName

Example with route:

import Ember from 'ember';

export default Ember.Route.extend({
  checkMyRouteName() {
    return this.routeName;
  }
})

回答5:

Just as an update, in Ember 1.8.1, we can get the routeName inside an Ember.Route object by doing this.routeName.

回答6:

Currently as of Ember 1.7.0 you can get the current route from within a route by calling this.routeName.

回答7:

The Ember namespace API now has a getOwner method, which is very useful for looking up the currentRouteName, or, other route properties.

  const owner        = Ember.getOwner(this);
  const currentRoute = owner.lookup('router:main').currentRouteName;
  const routeInfo    = owner.lookup(`route:${currentRoute}`).get('info');
  // etc.

I've created an Ember Twiddle example to demonstrate. Use the text input above the "Output" pane to hit other routes like /blue, /green, or /red.

I had the same problem for a while. then i started exploring router. It always have a state object which can be obtained from any route using

var route = this;
var handlerInfos = route.get("router.router.state.handlerInfos");
var currRouteHandlerInfo = handlerInfos[handlerInfos.length-1];
var currRouteName = currRouteHandlerInfo.name; //"home"

that's it. Now you have the current route name!

if you want the current route params,

var routerParams = this.get("router.router.state.params");
var currRouteParams = routerParams[currRouteName]; //{ homeId : "1" }

You can simple parse the current URL. This way you can use your full url for example:

http://127.0.0.1:8000/index.html/#/home

and extract from this string the suffix:

/home

which is the current route name.

A simple JS function (that works regardless to your Ember version) will be:

function getCurrentRoute()
{
    var currentRoute;
    var currentUrl = window.location.href; // 'http://127.0.0.1:8000/index.html/#/home'

    var indexOfHash = currentUrl.indexOf('#');
    if ((indexOfHash == -1) ||
        (indexOfHash == currentUrl.length - 1))
    {
        currentRoute = '/';
    }
    else
    {
        currentRoute = currentUrl.slice(indexOfHash + 1); // '/home'
    }

    return currentRoute;
}

Example of use:

if (getCurrentRoute() == '/home')
{
// ...
}
