| /** | |
| * Adds support for a "hover" event. The event provides a convenience wrapper | |
| * for subscribing separately to mouseenter and mouseleave. The signature for | |
| * subscribing to the event is</p> | |
| * | |
| * <pre><code>node.on("hover", overFn, outFn); | |
| * node.delegate("hover", overFn, outFn, ".filterSelector"); | |
| * Y.on("hover", overFn, outFn, ".targetSelector"); | |
| * Y.delegate("hover", overFn, outFn, "#container", ".filterSelector"); | |
| * </code></pre> | |
| * | |
| * <p>Additionally, for compatibility with a more typical subscription | |
| * signature, the following are also supported:</p> | |
| * | |
| * <pre><code>Y.on("hover", overFn, ".targetSelector", outFn); | |
| * Y.delegate("hover", overFn, "#container", outFn, ".filterSelector"); | |
| * </code></pre> | |
| * | |
| * @module event | |
| * @submodule event-hover | |
