Introduction
The mobile computing landscape is changing rapidly. Smartphones are no longer niche devices reserved for technology enthusiasts or executive staff. Businesses are increasingly deploying mobile solutions for field employees, sales teams, service technicians, healthcare professionals, and customers who expect access to information regardless of location.
Developers, however, face a significant challenge. The mobile ecosystem has become increasingly fragmented. Apple's iPhone continues to gain popularity, Android devices are expanding quickly across multiple manufacturers, BlackBerry remains dominant within many enterprise environments, Nokia continues to maintain a significant global presence, and Windows Phone 7 is entering the market.
Building separate native applications for every platform requires multiple programming languages, development environments, testing strategies, and deployment processes. For many organizations, this significantly increases development costs and extends project timelines.
jQuery Mobile has emerged as an ambitious attempt to simplify mobile web application development. Built upon the success of the jQuery JavaScript library, it seeks to provide developers with a consistent framework for creating touch-friendly interfaces that work across a wide range of smartphones and mobile browsers.
As of October 2010, jQuery Mobile is still an emerging technology. While it is not intended to replace native applications in every scenario, it offers an attractive option for organizations seeking broader device compatibility without maintaining multiple codebases.
This article examines how jQuery Mobile works, its architectural principles, enterprise use cases, strengths, limitations, and recommendations for organizations evaluating mobile web technologies.
The Rise of Mobile Web Applications
Traditional desktop-oriented websites often perform poorly on mobile devices.
Common issues include:
- ◆Small navigation elements
- ◆Mouse-dependent interactions
- ◆Fixed-width layouts
- ◆Slow loading times
- ◆Difficult text input
- ◆Inconsistent browser behavior
Users increasingly expect interfaces specifically designed for touch interaction.
Rather than simply shrinking desktop websites, organizations must rethink the user experience for smaller screens.
Why Cross-Platform Development Matters
Supporting multiple mobile operating systems independently introduces significant complexity.
Development teams may need expertise in:
- ◆Objective-C for iPhone
- ◆Java for Android
- ◆BlackBerry Java
- ◆C# for Windows Phone
- ◆Various SDKs and deployment tools
Maintaining feature parity across multiple applications becomes increasingly difficult as projects grow.
A web-based approach offers the possibility of writing a single application that operates across many supported devices.
What Is jQuery Mobile?
jQuery Mobile is a user interface framework built on top of jQuery.
Its primary goals include:
- ◆Cross-platform compatibility
- ◆Touch-optimized controls
- ◆Consistent user interface components
- ◆Progressive enhancement
- ◆Reduced browser-specific coding
Rather than requiring developers to build separate interfaces for every mobile platform, the framework provides reusable components that adapt to different devices.
Core Technologies
jQuery Mobile leverages familiar web standards.
These include:
- ◆HTML5
- ◆CSS3
- ◆JavaScript
- ◆jQuery
- ◆AJAX navigation
Organizations already developing web applications can often leverage existing skills when adopting the framework.
Touch-Friendly User Interface Components
One of jQuery Mobile's primary objectives is simplifying touch interface development.
Built-in components include:
- ◆Buttons
- ◆Toolbars
- ◆Navigation bars
- ◆Lists
- ◆Forms
- ◆Dialogs
- ◆Pop-up pages
- ◆Content panels
These controls are optimized for finger-based interaction rather than mouse input.
Progressive Enhancement
An important design principle within jQuery Mobile is progressive enhancement.
Applications begin with standard semantic HTML.
The framework then enhances supported browsers with richer styling and interactions.
This approach offers several advantages:
- ◆Improved accessibility
- ◆Cleaner markup
- ◆Better compatibility
- ◆Easier maintenance
Developers can focus on application functionality while allowing the framework to manage many presentation concerns.
Simplified Page Structure
A typical jQuery Mobile page follows a structured layout.
<div data-role="page">
<div data-role="header">
<h1>Customer Portal</h1>
</div>
<div data-role="content">
Content goes here.
</div>
<div data-role="footer">
Footer Information
</div>
</div>Using data attributes, developers can rapidly construct mobile-friendly interfaces without extensive custom styling.
AJAX Navigation
jQuery Mobile makes extensive use of AJAX to improve navigation.
Instead of performing a complete page refresh, content can be loaded dynamically.
Potential benefits include:
- ◆Faster page transitions
- ◆Reduced bandwidth usage
- ◆Improved user experience
- ◆Smoother navigation
For mobile users operating on slower wireless connections, minimizing unnecessary page reloads can significantly improve perceived responsiveness.
