BackboneJS - View $el

Quiz

Description

It represents a cached jQuery object for the view's element. A handy reference instead of re-wrapping the DOM element all the time.

Syntax

view.$el

Example

<!DOCTYPE html>
<html>

      <script src="/?originalUrl=https%3A%2F%2Fcode.jquery.com%2Fjquery-2.1.3.min.js"

         type = "text/javascript"></script>
   </head>
   
   <body>
      <div id = "myapp"></div>
      <script type = "text/javascript">
      
         //'ViewDemo' is a name of the view class
         var ViewDemo = Backbone.View.extend ({

            //'el' is a view reference in which every element of view associate with 
            //HTML content will be rendered
            el: '#myapp',

            //This function is called when the view is instantiated
            initialize: function() {
               this.render();  //render method specifies how to handle and what to display in the view
            },

            //'$el' is cached object which pushes the content defined within it
            render: function() {
               this.$el.html("Welcome to Tutorialspoint!!!");
            }
         });

         //'myview' is a instance of the 'ViewDemo' class
         var myview = new ViewDemo();
      </script>
