返回值:jQueryhover([over,]out)

概述

一个模仿悬停事件(鼠标移动到一个对象上面及移出这个对象)的方法。这是一个自定义的方法,它为频繁使用的任务提供了一种“保持在其中”的状态。

当鼠标移动到一个匹配的元素上面时,会触发指定的第一个函数。当鼠标移出这个元素时,会触发指定的第二个函数。而且,会伴随着对鼠标是否仍然处在特定元素中的检测(例如,处在div中的图像),如果是,则会继续保持“悬停”状态,而不触发移出事件(修正了使用mouseout事件的一个常见错误)。

参数

over,outFunction,FunctionV1.0

over:鼠标移到元素上要触发的函数

out:鼠标移出元素要触发的函数

outObjectV1.4

当鼠标移到元素上或移出元素时触发执行的事件函数

示例

over,out 描述:

鼠标悬停的表格加上特定的类

jQuery 代码:
$("td").hover(
  function () {
    $(this).addClass("hover");
  },
  function () {
    $(this).removeClass("hover");
  }
);

out 描述:

hover()方法通过绑定变量"handlerInOut"来切换方法。

jQuery 代码:
$("td").bind("mouseenter mouseleave",handlerInOut);
$("td").hover(handlerInOut);
