检查jQuery .hover操作是否已绑定 [英] Checking if jQuery .hover action is already binded

问题描述

是否有任何方法可以检查某个元素是否已经由jQuery .hover函数触发的动作?

Is there any way to check if an element already has an action, triggered by jQuery .hover function?

推荐答案

您可以通过选中element.data('events')['eventName']

如果悬停，它将是:

var hasHover = x.data('events')['mouseover'] && x.data('events')['mouseout'];

在jQuery 1.8及更高版本中，您必须使用$._data进行访问，如此答案

In jQuery 1.8 and later, you must access it using $._data as mentioned in this answer

即

var events = $._data(obj[0], "events");
var hasHover = events['mouseover'] && events['mouseout'];
