Code: load handler with cached images and IE

Just had a strange case, that the load event of an image is not fired. After a short research I found the issue…

Not working code:
$('img').attr('src', 'image.jpg').load(function() {
//Do something - but it doesn't
});

Working code:
$('img').load(function() {
//Do something - it does
}).attr('src', 'image.jpg');

The thing is IE (and Opera) will load the cached image directly before your event handler is attached…

It is jQuery Notation but also applies to Vanilla JS.
