EmberJS - Views

Quiz

Introduction

A view in an Ember.js is used for to handle user events and also creates the re-usable component. The UI will be developed by using the views.

The below figure shows how event handling occurs −

When user clicks on the event the view turns a primitive event (a click) into a semantic event (Event Handling) and transferred to the Ember.Route for to get the event action.

Defining a View

Handlebars templates in Ember.js are powerful and can be rendered by using Ember.View and inserted into DOM. You can set templateName property of a view to indicate which template to use.

Ember.View.create({
   templateName: 'NameOfTemplate',
   //do the logic
});

In the above code, the templateName determines which template should be rendered when an application request for a view.
