Backbone.js view.$()

The Backbone.js $(jQuery) method is used to run queries scoped within the view's element. After using this, you don't have to use model ids within your query to fetch specific elements in a list, and can rely much more on HTML class attributes. It is same as running: view.$el.find(selector)

Syntax:

Parameter explanation:

selector: It specifies the different types of selectors i.e. id or class.

Let's take an example.

See this example:

 <!DOCTYPE html>
   <head>
      <title>View $(jQuery) Example</title>
         <script src="https://code.jquery.com/jquery-2.1.3.min.js" type="text/javascript"></script>

   </head>
   <body>
   <div id="myVal">
        <button id="button" data-test="">Click Me</button>
    </div>
   <span id="myLog"></span>
      <script type="text/javascript">

         var myLog = $('#mydata');
         var data = function(val) {
            document.write(val);
         };
         var ViewDemo = Backbone.View.extend({
            events: {
               'click [data-test]' : 'myFunc1',
               'click *[data-test]': 'myFunc2',
            },

            el: $('#myVal'),

            myFunc1: function () {
               data('Welcome to JavaTpoint');
            },
            myFunc2: function () {
               data(': A solution of all technology...');
            }
        });
        var myview = new ViewDemo();
        </script>
        </body>
     </html>
