<p>The <code>.hover()</code> method binds handlers for both <code>mouseenter</code> and <code>mouseleave</code> events. We can use it to simply apply behavior to an element during the time the mouse is within the element.</p>
|
|
<p>Calling <code>$(selector).hover(handlerIn, handlerOut)</code> is shorthand for:</p>
|
|
<pre>$(selector).mouseenter(handlerIn).mouseleave(handlerOut);</pre>

<p>The <code>.hover()</code> method, when passed a single function, will execute that handler for both <code>mouseenter</code> and <code>mouseleave</code> events. This allows the user to use jQuery's various toggle methods within the handler.</p>
