Providing fixes for "input" event

In HTML5 draft specification there is a new event called "input" which fires *as soon as* data is input into a form (e.g. before the element loses focus - so before "change" would fire). This is very useful for form handling.

As it is an HTML5 feature it is naturally supported by only some of the most recent browsers (e.g. Chrome 8). It would be brilliant if jQuery could provide a fix so that the "input" event could display the same behaviour in all browsers (like it has done for preventDefault() etc.)

I haven't fully diagnosed how the "input" event works, but I imagine it would be similar to:

    'keyup click change',
    function(evt) {
        if($(this).tagName.match(formElements) && formHasChanged()) {
            // Fire event
        } else {

Obviously this is only rudimentary pseudo-code. The actual solution would be far more complex I'm sure.

Actually there are a whole bunch of new HTML5 events, and it would be very awesome if jQuery were to provide backward compatibility fixes for all of them.

I found this great plugin that seems to implement a lot of the actual HTML5 forms functionality However, it doesn't seem to extend to include relevant events, or pseudoclasses.

I think there's a logical separation here. Extra functionality, like "autofocus", "placeholder", "required" belong in a plugin. However, things like events and pseudoclasses seem to me to belong in Core.

To that end I think it would be great if jQuery could try to implement functionality for legacy browsers for:

New events:

New pseudoclasses:
