.is(":hover") 自 jQuery 1.9 起已损坏 如何修复 [英] .is(":hover") is broken as of jQuery 1.9 How to fix

问题描述

When doing $(...your selector here...).is(":hover"), jQuery prior to 1.9.1 gave correct answer, while jQuery 1.9.1 tells you this:

Error: Syntax error, unrecognized expression: unsupported pseudo: hover

This is not about performing an action on hover - for that, just use .hover() This is about, at an arbitrary point in time, finding out whether or not some element is being hovered

Thank you Mooseman for the answer, which I shall demonstrate with a fiddle

解决方案

Assuming your selector is #myid, use $('#myid:hover') instead of using .is().

If you are using $(this) or a variable, use myVar.filter(':hover').
