There are many languages and frameworks used to create the websites we know and love, JavaScript being one of the most widespread.

Nearly every website from Facebook to the BBC uses JavaScript in some way, but as time has passed its syntax has become a little dated, and often writing the simplest of things can be a bit long-winded.

Enter jQuery!

jQuery is an open source framework that provides a set of tools and libraries to make writing JavaScript easier and faster. With jQuery, HTML document traversing, event handling, animating and AJAX interactions are faster and more effective than writing in pure JavaScript.

Released in 2006, its popularity has soared. In fact, out of the 10,000 most visited websites, 55% use jQuery in some way making it the most popular JavaScript library currently in existence.

If you want to stay ahead in your field, and you're ready to embrace the development of feature rich websites, jQuery is for you.

The UKWDA offers a two day training course providing a comprehensive introduction to jQuery that focuses on the use of the jQuery framework, taking you from complete beginner to having a confident grasp of its use.

Why should I learn jQuery?

JavaScript has been around for years and is an immensely powerful client site programming language - jQuery improves the simplicity of its use meaning you write fewer lines of code to achieve the same result.

The syntax of jQuery makes it easier to learn than traditional JavaScript. Furthermore, it is cross-browser compatible - something that is crucial in today's web environment.

What are the main features of jQuery?

The jQuery library provides easy HTML element selection, manipulation and traversal, simple JavaScript event methods, CSS manipulation, effects and animations, AJAX requests and much more.

With jQuery, creating an engaging user experience is faster and more rewarding. When you're writing fewer lines of code to achieve the same great result, you give your users a rich browsing experience and take more enjoyment from the development process.

The following websites showcase some of the great results that can be achieved with jQuery:

Pattern Tap offers sortable content, on hover effects, animation of DOM elements and modal window overlays.

John Kavanagh's portfolio site benefits from AJAX loading, animated effects and a horizontal scroll interface.

The BBC Sport website boasts live news feeds, calendar widgets and auto-populating content for events as and when they happen.

Can jQuery accommodate plugins?

Yes, jQuery's structure is designed to integrate with many third party plugins allowing even further functionality.

Some popular plugins available to complement your jQuery website are:

  • Nivo slider - A customisable horizontal slider
  • SpellCheck - Adds a simple spelling check tool to your text areas 
  • Ken Burns Sliders - Add a stunning "Ken Burns" effect to your images 
  • Live Search - Help users search faster with this dynamic search bar

What do I need to know before I can learn jQuery?

Much of the functionality provided through jQuery allows manipulation of the visual elements of a web page. As such, you should be comfortable with HTML and CSS before setting out to master jQuery.

What can I expect from the UKWDA jQuery Introduction course?

The two day course will give you hands-on training in all aspects of using jQuery and combines theory with practical exercises. You will be guided through the practical application of jQuery to improve your knowledge and build confidence in its use.

After attending the course, you will feel comfortable with creating common web page interactions such as changing content, providing tooltips, animations, effects and rich user interface elements.

What topics does the course cover?

The course is broken down into the following modules:

  • Introduction
  • The Query part: retrieving and traversal
  • Types of filters
  • Manipulating content
  • Working with CSS
  • Handling Events
  • Animation
  • Extending jQuery

Where does the course take place?

The course takes place over two days in London. Classes start at 10am and usually finishing between 4.30pm and 5pm.

We'll provide you with a Certificate of Attendance, lunch, course notes and six months of free help desk support. We can also advise you on local accommodation if you need it.

The cost of the jQuery: Introduction course is £675. UKWDA members can log in to the member area to obtain a 10% discount code.
