jQuery UI 1.7: The User Interface Library for jQuery

Overview of this book

Modern web application user interface design requires rapid development and proven results. jQuery UI, a trusted suite of official plug-ins for the jQuery JavaScript library, gives you a solid platform on which to build rich and engaging interfaces with maximum compatibility and stability, and minimum time and effort. jQuery UI has a series of ready-made, great-looking user interface widgets and a comprehensive set of core interaction helpers designed to be implemented in a consistent and developer-friendly way. With all this, the amount of code that you need to write personally to take a project from conception to completion is drastically reduced. Specially revised for version 1.7 of jQuery UI, this book has been written to maximize your experience with the library by breaking down each component and walking you through examples that progressively build upon your knowledge, taking you from beginner to advanced usage in a series of easy-to-follow steps. In this book, you'll learn how each component can be initialized in a basic default implementation and then see how easy it is to customize its appearance and configure its behavior to tailor it to the requirements of your application. You'll look at the configuration options and the methods exposed by each component's API to see how these can be used to bring out the best of the library. Events play a key role in any modern web application if it is to meet the expected minimum requirements of interactivity and responsiveness, and each chapter will show you the custom events fired by the component covered and how these events can be intercepted and acted upon.

Using slider's event API

In addition to the options we saw earlier, there are an additional four options that can be used to define functions which are executed at different times during a slider interaction. Any callback functions we use are automatically passed the standard event object and an object representing the slider. The following table lists the event options we can use with slider:

Function

Usage

change

Called when the slider handle stops and its value has changed.

slide

Called every time the slider handle moves.

start

Called when the slider handle starts moving.

stop

Called when the slider handle stops.

Hooking into these built-in callback functions is extremely easy. Let's put a basic example together to see. Change the configuration object in slider10.html so that it appears as follows:

var sliderOpts = {
  start: function() {
		  
    $("#tip").fadeOut(function() {
      $(this).remove();
    });
  },
  change: function(e, ui) {
		    
    $("<div>").attr(...
