Preface of Web Development with jQuery by Richard York
Some examples are methods that help you to select elements from a markup document through the DOM and methods that help you to traverse through those selections and fi lter them using jQuery’s fi ne-grained controls.
This makes working with the DOM easier and more effortless. It also covers jQuery’s event model, which both wraps around the normal W3C event API and provides an API that when used correctly can heavily optimize and reduce complexity in your applications.
Later in the book, you see how to leverage the jQuery UI library to make user interface (UI) widgets. jQuery gives you the ability to break up content among multiple tabs in the same page. You have the ability to customize the look and feel of the tabs, and even to create a polished look and feel by providing different effects when you mouse over tabs and click them. The jQuery UI library also makes it easy to create accordion sidebars.
These sidebars have two or more panels, and when you mouse over an item, one pane transitions to another via a smooth, seamless animation wherein the preceding pane collapses and the proceeding pane expands.

The jQuery UI library also gives you the ability to make any element draggable with the mouse cursor; by clicking, holding and moving the mouse, you can move elements around a page to any position you like. It also makes it easy to create drag-and-drop user interfaces. You can use jQuery UI to make droppable zones, where you take elements from other parts of a page and drop them on another, similarly to how you might interact with your operating system’s fi le manager when you want to move a folder from one place to another.

You can also make lists that are sortable via dragand-drop, rearranging elements based on where you drop them. You can have a user interface where you drag the mouse cursor to make a selection, as you would in your operating system’s fi le manager when you want to select more than one fi le or folder. jQuery UI exposes the ability to resize elements on a page using the mouse.

jQuery UI gives you the ability to make professional user-interface widgets with much less development effort.
