According to jquerymobile. But jQuery Mobile was mainly created for developing web applications for smaller screens. Take the statements about being a cross-browser framework with a grain of salt, too. After that, you need to add some event listeners and scripts, and start debugging. The jQuery Mobile website has all you need to start using this library. You can find lots of learning materials in the Demos section: tutorials, an API reference, and samples. The Download section contains links for the library itself. There are two ways of including jQuery Mobile in the source code of your application: either download and uncompress the ZIP file in your local directory and specify this location in the source code of your application, or include the URLs of the content delivery network CDN —hosted files.

After the mockup of your application is ready see Prototyping the Mobile Version , you know how many pages your application will have and how to navigate among them. The HTML5 specification includes an important feature: you can add to any HTML tag any number of custom nonvisible attributes , as long as they start with data- and have at least one character after the hyphen.

In jQuery Mobile, this feature is being used in a very smart way. When this application starts, the user will see only the content of the page Donate because it is included in the code first.

You can then specify the corresponding roles to each of these sections:. But if you do, the code will be better structured, and additional styling can be applied in the CSS based on these attributes. The preceding code sample is a complete HTML document that you can test in your browser. If you use desktop web browser, the web page will look like Viewing the document in Firefox.

Any mobile web developer wants to see how his web application will look on mobile devices. There two major ways of doing this: either test it on a real device or use a software emulator or simulator. For example, you can use one of the handy tools such as the Apache Ripple emulator. Using emulators really helps in development. Ripple emulates not only the screen resolutions, but some of the hardware features, as well simulators usually simulate only the software.

For example, you can test an accelerometer by using the corresponding menu item under Devices at the upper left in Viewing the document in the Ripple emulator or Geo Location under Settings at the upper right in Viewing the document in the Ripple emulator. For example, the fonts might look a little different. If you can afford it, hire real mobile users carrying different devices. You can do this through the Mob4Hire testing as a service TaaS website. The good news is that creators of jQuery Mobile use about 70 physical devices for testing of their UI components, but still, you might want to see how your application looks and feels on a variety of devices.

If you want to see how your application looks on a real device that you own, the easiest way is to deploy your application on a web server with a static IP address or a dedicated domain name. After the code is modified, you need to transfer the code to that remote server and enter its URL in the address bar of your mobile device browser. You might not like the design of the navigation bar shown in Viewing the document in Firefox , but it has some style applied to it.

Where are the white letters on the black background coming from? This is the power of the custom data- attributes in action. The creators of jQuery Mobile included in their CSS predefined styling for data- attributes, including the inner buttons of the navbar. Create your own CSS, but first see whether you like some of the off-the-shelf themes offered by jQuery Mobile. You can have up to 26 prestyled sets of toolbars, content, and button colors called swatches. But you can use the data-theme attribute with any HTML element, not necessarily the entire page or other container.

By default, the header and the footer use swatch A, and the content area uses swatch C. To change the entire color scheme of Viewing the document in the Ripple emulator to swatch A the background of the content area will become dark gray , use the following line:. The href attribute responsible for navigation includes a hash character followed by the corresponding ID. For example, if the name of the preceding document is navigation1. This is all it takes to ensure that the Back button displays at the left side of the page header, and that when the user taps on it, the application navigates to the Donate page.

The Statistics page with the Back button shows a snapshot of the Ripple emulator after the user clicks the link on the Donate page. The Statistics page now includes the fully functional Back button. The stats. The anchor tag simply refers to the URL of stats. In this case, jQuery Mobile loads stats. The HTML of the main page shows the main page. Running this version of our simple two-page application produces the same results. The second page looks exactly like The Statistics page with the Back button.

If you use single-page documents, the name of the file with the page will be added to the URL. So which template style should you use? Both have their pros and cons. If the code base of your application is large, use a single-page template.

The code will be split into multiple pages, will be easier to read, and will give you a feeling of being modular without implementing any additional libraries for cutting the application into pieces. This all sounds good, but be aware that with single-page templates, whenever you navigate from one page to another, your mobile device makes a new request to the server.

The user will see the wait cursor until the page arrives at the device. Even if the size of each page is small, additional requests to the server are costlier with mobile devices because they need another second just to re-establish a radio link to the cell tower. After communication with the server is done, the phone lowers its power consumption. However, a new request to the server for loading the page starts increasing power consumption again. Hence, using the multipage template might provide smoother navigation.

On the other hand, there is a way to prefetch pages into the DOM even in single-page mode such that the number of server requests is minimized.

Test your application in both single-page and multipage modes and see what works best. Web developers use a technique called progressive enhancement , especially in the mobile field. The idea is simple: first make sure that the basic functionality works in any browser, and then apply the bells and whistles to make the application as fancy as possible by using CSS or framework-specific enhancements.

But what if you decide to go the opposite route and take a nice-looking UI and remove its awesomeness? We are testing a situation in which, for whatever reason, we need to remove jQuery Mobile from our code base. The code still works! The web browser ignores the custom data- attributes without breaking anything.

With jQuery Mobile, you can create a button in many ways. There are multiple examples in the Buttons section of the product documentation. The following code produces five buttons, which will look the same but have different labels:. Such "surgery" usually lasts at least two weeks. One of the ways to arrange navigation is to add persistent toolbars that never go away while your application is running.

You can add such a toolbar in the footer or header area or in both. Suppose that your application has a starting page and four other pages that can be selected by the user. Four pages in the footer shows the initial view of the application. If the user taps one of the four pages in the footer, the program replaces the starting page with the selected one, and the title of the selected page in the footer becomes highlighted.

In the printed version, the different background colors might not be so obvious, but you have to trust us on this or run the code sample on your own. In jQuery Mobile, implementing persistent toolbars is simple. The file page2. The main page with header, content, and footer sections presents the code of the main page index. This code also defines the header, content, and footer areas.

For example:. But you can also invoke this method with a second parameter, which is an object. You can specify such parameters as data the data to send with the Ajax page request , changeHash a boolean to control if the hash in the URL should be updated , and others. After the brief introduction to the jQuery Mobile library, we and you are eager to start hands-on coding. It will be sliced into a set of screens pages , and the user will see one page at a time.

Designs and layouts for each screen of the mobile version are shown in this section as images taken from the Balsamiq tool. In this book, we test only mobile devices with screen sizes of x and x pixels. The Starting page portrait shows two versions of the starting page mockup in portrait mode. The About page portrait shows two versions of the About page mockups in portrait mode. Figures and also show mockups in portrait mode; The Who We Are section of the About page portrait displays two versions of the Who We Are page, and The Donate page portrait depicts two versions of the Donate page.

The Donate page portrait illustrates a term Above the Fold used by web designers. This term originated in the newspaper business. It refers to the upper half of the first page of a broadsheet newspaper that has been folded for display and sale at a newstand. In web design, Above the Fold refers to the content on a web page that a user can see without needing to scroll.
