jQuery UI 1.10: The User Interface Library for jQuery - Fourth Edition

Overview of this book

jQuery UI, the official UI widget library for jQuery, gives you a solid platform on which to build rich and engaging interfaces quickly, with maximum compatibility, stability, and effort. jQuery UI's ready-made widgets help to reduce the amount of code that you need to write to take a project from conception to completion. jQuery UI 1.10: The User Interface Library for jQuery has been specially revised for Version 1.10 of jQuery UI. It is written to maximize your experience with the library by breaking down each component and walking you through examples that progressively build up your knowledge, taking you from beginner to advanced user in a series of easy-to-follow steps. Throughout the book, you'll learn how to create a basic implementation of each component, then customize and configure the components to tailor them to your application. Each chapter will also show you the custom events fired by the components covered and how these events can be intercepted and acted upon to bring out the best of the library. We will then go on to cover the use of visually engaging, highly configurable user interface widgets. At the end of this book, we'll look at the functioning of all of the UI effects available in the jQuery UI library.

Mode

Implementation

fit

The drag object must be completely within the boundary of the droppable for it to be considered over it.

intersect

At least 25 percent of the drag object must be within the boundary of the droppable before it is considered over it.

pointer

The mouse pointer must touch the droppable boundary before the drag object is considered over the droppable.

touch

The drag object is over the droppable as soon as an edge of the drag object touches an edge of the droppable.

So far, all of our droppable examples have used intersect, which is the default value of the tolerance option. Let's see what difference the other values for this option make to an implementation of the component. Revert to the #drag and #target IDs from their respective...
