mutation observers - Catching a CSS change with jQuery -


what want find out when css value has been changed element through css. let's background-color has been changed else. example using :hover.

at first thought mutation observer resolve wrong. when there's change style of element inside css file doesn't affect style attribute element. example, let's have element id "test":

$('#button').click(function () {     $('#test').css('backgroundcolor', 'blue'); });

this being detected mutation observer style change.

however doing in css file doesn't trigger event:

#test:hover {     background-color: blue; }

so asking - there way find out, preferably using jquery, when change has been made in css file element?

no, unfortunately not (unless changed javascript - it's not in case).

the thing left specify why you're wanting this, , maybe there'll way of meeting requirements in different way. may falling victim xy problem here:

note: obviously, use of constant polling of background-color of element can achieve degree of accuracy (depends on frequency of check), wouldn't advise .
