返回值:jQuery
mouseleave([[data],fn])
概述
当鼠标指针离开元素时，会发生 mouseleave 事件。该事件大多数时候会与mouseenter 事件一起使用。
与 mouseout 事件不同，只有在鼠标指针离开被选元素时，才会触发 mouseleave 事件。如果鼠标指针离开任何子元素，同样会触发 mouseout 事件。
参数
fnFunctionV1.0
在每一个匹配元素的mouseleave事件中绑定的处理函数。
[data],fnString,FunctionV1.4.3
data:mouseleave([Data], fn) 可传入data供函数fn处理。
fn:在每一个匹配元素的mouseleave事件中绑定的处理函数。
示例
描述:
当鼠标指针离开元素时，改变元素的背景色：：
jQuery 代码:
$("p").mouseleave(function(){
$("p").css("background-color","#E9E9E4");
});
