How do I change query parameters in Ember?

问题

I'm writing an action handler in route:application:

actions: {
  changeFoo(foo) {
    // I want to change the fooId queryParam to foo.get('id')
  }
}

The problem is that the only documented ways I can find to change the query params are transitionTo('some.route', someModel, { queryParams: { ... } } and the replaceWith version of the same. But I'm in route:application, so I don't know the current route's name. That means I don't know what the first argument to transitionTo would be.

Is there another way to get the URL to become ?fooId=123?

回答1:

You don't need current route name. You can just do 'transitionTo({queryParams: { foo: 123 })'. The router will apply it to the correct route.

回答2:

From controller:application you can set the query param foo like this:

import Ember from 'ember';

export default Ember.Controller.extend({
  queryParams: ['foo'],

  actions: {
    updateMyQueryParam() {
      this.set('foo', 'hello');
    }
  }
});
