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

Here is a workaround (answering not necessary.)

short answer, check whether

.parent().find(":hover")

has length 1, and contains the element in question.

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
