There is no need to use inline event handler.
One can always add capturing listener to window for example.
window.addEventListener("canplay",
function(e) {
if (e.target == document.querySelector('video') {
// Do something.
}
}
, true);
And just do that before the <video> element occurs in the page.
That is simple, IMHO.
jQuery cannot do anything more than that. So if you add the event
listener using jQuery after the <video> element, "canplay" may have
already fired.
(I wonder why the "Firing a simple event named e" defaults to
non-bubbling. It makes many things harder than they should be.)
