To launch a modal from a URL change in Ember.js, you can use the beforeModel hook in your route to check for a specific query parameter or segment in the URL and trigger the modal display accordingly. Here is an example of how you can achieve this:


First, define a route where you want to show the modal:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
// app/routes/example-route.js

import Route from '@ember/routing/route';

export default class ExampleRoute extends Route {
  beforeModel(transition) {
    if (transition.to.queryParams.showModal) {
      this.controllerFor('example-modal').send('showModal');
    }
  }
}


Next, create a controller for the modal that will handle showing and hiding the modal:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17
// app/controllers/example-modal.js

import Controller from '@ember/controller';

export default class ExampleModalController extends Controller {
  isModalVisible = false;

  actions: {
    showModal() {
      this.set('isModalVisible', true);
    },

    hideModal() {
      this.set('isModalVisible', false);
    }
  }
}


Finally, add a component for your modal in your template:

1
2
3
4
5
6
7
<!-- app/templates/components/example-modal.hbs -->

{{#if this.isModalVisible}}
  <div class="modal">
    <!-- modal content here -->
  </div>
{{/if}}


Now, when the URL changes and includes a query parameter showModal=true, the modal will be displayed automatically in your Ember application. Don't forget to customize the modal component and add CSS styles to make it look good in your application.
