In Ember.js, you can hide a view by using the "isVisible" property. By setting this property to false, you can effectively hide the view from the DOM without destroying it. This can be done by either setting the property directly in the template or by using a conditional statement in the view's JavaScript file. By toggling the value of isVisible, you can control when the view is displayed or hidden based on your application's logic. Additionally, you can also use CSS to hide a view by setting its "display" property to "none" or by adding a class that hides the view. This can be useful for more dynamic hiding and showing of views based on user interactions or other events in your application.
What are some examples of hiding views in ember.js in real-world applications?
- Conditional rendering: You can hide certain views in Ember.js based on a given condition. For example, you can hide a pop-up modal if a certain user action hasn't been triggered yet.
- Dynamic component loading: You can load and render certain components dynamically based on user interactions or other events. This allows you to show or hide specific views as needed.
- Authenticated routes: In an application that requires authentication, you can hide certain views for users who are not logged in. This can be achieved by implementing authentication logic and conditionally rendering views based on the user's authentication status.
- Conditional styling: You can hide views by manipulating their CSS styles based on certain conditions. For example, you can set the style display property to "none" to hide a view when a specific button is clicked.
- Ember service integration: You can use Ember services to control the visibility of views based on external data or events. This allows for more flexible and reusable ways to hide views in your Ember.js application.

How to hide a view in ember.js with a toggle effect?
One way to hide a view in Ember.js with a toggle effect is to use a property in the controller to control the visibility of the view. Here's an example of how you can do this:
- Define a property in the controller to track the visibility of the view:
1 2 3 4 5 6 7 |
// controllers/example.js import Controller from '@ember/controller'; export default Controller.extend({ isHidden: false }); |
- Use the {{if}} helper in the template to conditionally render the view based on the value of the isHidden property:
1 2 3 4 5 6 7 |
{{! templates/example.hbs }} <button {{action "toggleView"}}>Toggle View</button> {{#if isHidden}} <div>Hidden view</div> {{/if}} |
- Define an action in the controller to toggle the value of the isHidden property:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
// controllers/example.js import Controller from '@ember/controller'; export default Controller.extend({ isHidden: false, actions: { toggleView() { this.toggleProperty('isHidden'); } } }); |
Now, when the "Toggle View" button is clicked, the isHidden
property will be toggled and the view will be hidden or shown based on its value.
How to hide a view in ember.js using Ember.js mixins?
To hide a view in Ember.js using mixins, you can create a mixin that adds a CSS class to the view's element when a specific property is set. Here's an example of how you can do this:
- Create a mixin that adds a hidden CSS class to the view's element:
1 2 3 4 5 6 7 8 9 10 |
// mixins/hideable.js import Ember from 'ember'; export default Ember.Mixin.create({ classNameBindings: ['isHidden:hidden'], isHidden: Ember.computed('hide', function() { return this.get('hide'); }), }); |
- Add the hide property to the view where you want to hide it:
1 2 3 4 5 6 7 |
// components/my-component.js import Ember from 'ember'; import HideableMixin from '../mixins/hideable'; export default Ember.Component.extend(HideableMixin, { hide: true, }); |
- Update the template for the view to include the hidden class:
1 2 |
<!-- templates/components/my-component.hbs --> <div class="my-component">My component content</div> |
With this setup, when the hide
property is set to true in the component, the hidden
class will be added to the component's element, effectively hiding it from view.
How to hide a view in ember.js using Ember.js services?
To hide a view in Ember.js using Ember services, you can create a service that tracks the visibility state of the view and then use this service in your template to conditionally hide or show the view.
Here's an example of how you can do this:
- Create a service that tracks the visibility state of the view:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
// app/services/visibility-service.js import Service from '@ember/service'; export default Service.extend({ isViewVisible: true, // Set initial visibility state to true hideView() { this.set('isViewVisible', false); }, showView() { this.set('isViewVisible', true); } }); |
- Inject the service into your component:
1 2 3 4 5 6 7 8 |
// app/components/my-component.js import Component from '@ember/component'; import { inject as service } from '@ember/service'; export default Component.extend({ visibilityService: service('visibility-service') }); |
- Use the service in your template to conditionally hide or show the view:
1 2 3 |
{{#if visibilityService.isViewVisible}} <div>Visible content</div> {{/if}} |
- You can then call the hideView() or showView() methods on the service to hide or show the view:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
// app/routes/my-route.js import Route from '@ember/routing/route'; import { inject as service } from '@ember/service'; export default Route.extend({ visibilityService: service('visibility-service'), actions: { hideView() { this.visibilityService.hideView(); }, showView() { this.visibilityService.showView(); } } }); |
By using this approach, you can easily control the visibility of a view in Ember.js using a service.
How to hide a view in ember.js using CSS?
To hide a view in Ember.js using CSS, you can use the display: none;
property in your CSS file.
First, you need to identify the view you want to hide by giving it a class or ID. For example, if you have a view with the class "hidden-view", you can hide it by adding the following CSS code:
1 2 3 |
.hidden-view { display: none; } |
Then, in your Ember.js template file, add the class to the view you want to hide:
1 2 3 |
<div class="hidden-view"> This content will be hidden </div> |
By applying the CSS class "hidden-view" to the view, it will be hidden on the page when the application is loaded.
