Yahoo! UI Library

Submodules:

event-base

Custom event engine, DOM event listener abstraction layer, synthetic DOM events.

event-delegate

Adds event delegation support to the library.

event-focus

Adds bubbling and delegation support to DOM events focus and blur.

event-key

Functionality to listen for one or more specific key combinations.

event-mouseenter

Adds subscription and delegation support for mouseenter and mouseleave events. Unlike mouseover and mouseout, these events aren't fired from child elements of a subscribed node.

This avoids receiving three mouseover notifications from a setup like

div#container > p > a[href]

where

Y.one('#container').on('mouseover', callback)

When the mouse moves over the link, one mouseover event is fired from #container, then when the mouse moves over the p, another mouseover event is fired and bubbles to #container, causing a second notification, and finally when the mouse moves over the link, a third mouseover event is fired and bubbles to #container for a third notification.

By contrast, using mouseenter instead of mouseover, the callback would be executed only once when the mouse moves over #container.

event-mousewheel

Adds mousewheel event support

event-resize

Adds a window resize event that has its behavior normalized to fire at the end of the resize rather than constantly during the resize.

event-synthetic

Define new DOM events that can be subscribed to from Nodes.
