jQuery Mobile is a web technology built on top of jQuery. It is used to create responsive web applications and websites which are accessible on phones, tabs, and desktops.

In this article, we will use the jQuery Mobile Toolbar addBackBtn option. When the addBackBtn option is set to true, a back button will be added automatically to the header which will take the user to the previous page. This option adds a back button only to the header toolbar widget and does not affect the footer.

Syntax:

$(".selector").toolbar({
  addBackBtn: true
});

 

  • Get the addBackBtn option:

    var addBackBtn = $( ".selector" )
        .toolbar( "option", "addBackBtn" ); 
  • Set the addBackBtn option:

    $(".selector").toolbar( "option", "addBackBtn", true );

CDN Links: First, add jQuery Mobile scripts needed for your project.

<link rel=”stylesheet” href=”https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css” />
<script src=”https://code.jquery.com/jquery-2.1.3.js”></script>
<script src=”https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.js”></script>

Example: In this example, we will set the addBackBtn option to true to add a back button to the header toolbar.
