You can select the libraries according to your need and click the Build My Download button.

Stable download

Click the Stable button, which leads directly to a ZIP file containing the CSS and JQuery files, for the latest version of jQuery mobile library. Extract the ZIP file contents to a jQuery mobile directory.

This version contains all files including all dependencies, a large collection of demos, and even the library's unit test suite. This version is helpful to getting started.

Download jQuery Library from CDNs

A CDN (Content Delivery Network) is a network of servers designed to serve files to the users. If you use a CDN link in your webpage, it moves the responsibility of hosting files from your own servers to a series of external ones. This also offers an advantage that if a visitor to your webpage has already downloaded a copy of jQuery mobile from the same CDN, it won't have to be re-downloaded. You can include the following CDN files into the HTML document.

//The jQuery Mobile CSS theme file (optional, if you are overriding the default theme)
<link rel = "stylesheet" href = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.css">

//The jQuery core JavaScript file
<script src = "https://code.jquery.com/jquery-1.11.3.min.js"></script>

//The jQuery Mobile core JavaScript file
<script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>

We are using the CDN versions of the library throughout this tutorial. We use AMPPS (AMPPS is a WAMP, MAMP and LAMP stack of Apache, MySQL, MongoDB, PHP, Perl & Python) server to execute all our examples.

Example

Following is a simple example of jQuery Mobile.

Live Demo 

<!DOCTYPE html>
<html>
   <head>
      <meta name = "viewport" content = "width = device-width, initial-scale = 1">
      <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-1.11.3.min.js"></script>
      <script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>
   </head>

   
      
   <body>
      <div data-role = "page" id = "pageone">
         <div data-role = "header">
            <h1>Header Text</h1>
         </div>

         <div data-role = "main" class = "ui-content">
            <h2>Welcome to Howcodex</h2>
         </div>

         <div data-role = "footer">
            <h1>Footer Text</h1>
         </div>
      </div>
   </body>
</html>

Details of the above code are −

  • This code is specified inside the head element.

<meta name = "viewport" content = "width = device-width, initial-scale = 1">

    • The viewport is used to specify (by the browser) to display the page zoom level and dimension.

    • content = "width = device-width" is used to set the pixel width of the page or screen device.

    • initial-scale = 1 sets the initial zoom level, when the page is loaded for the first time.

  • Include the following CDNs

<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-1.11.3.min.js"></script>
<script src = "https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.min.js"></script>

  • Content inside the <body> tag is a page displayed in the browser.

<div data-role = "page">
   ...
</div>

  • data-role = "header" creates the header at the top of the page.

  • data-role = "main" is used to define the content of the page.

  • data-role = "footer" creates the footer at the bottom of the page.

  • class = "ui-content" includes padding and margin inside the page content.

Output

Let's carry out the following steps to see how the above code works −

  • Save the above html code as simple_example.html file in your server root folder.

  • Open this HTML file as http://localhost/simple_example.html and the following output will be displayed.
