State of nested routes in EmberJS

问题

I have a route structure like this:

this.resource('A',function(){
  this.resource('B',function(){
    this.route('C');
  });
});

Is there a way I can check in A, which nested route of B is currently active?

For usability reasons I have a navigation in A, which also holds links for B.C and B.index But I only want to show one of those two links.

回答1:

The application controller has a property on it currentPath. You can use that to find out which path in the router you're currently on. It's the entire path, so it'd be A.B.C or A.B.index.

App.ColorsController = Ember.ArrayController.extend({
  needs:'application',
  atIndex: Em.computed.equal('controllers.application.currentPath', 'colors.index')
});
