jQuery triggers keyup event only if it was attached with jQuery

Realy messed up with triggering keyup event using jQuery.

Here is the clean example

http://jsfiddle.net/xQcGM/2/

When I开发者_JAVA技巧 type in any of input's, they both fire event, but when I try to fire it programmatically ($(element).trigger('event')) only the second one is triggered, but I expect both.

Where do i miss something?

UPD I can't change the way handler was attached!

The native way to trigger events is to call dispatchEvent. Unfortunately, this method does not appear anywhere in jQuery's source. So I am guessing you have to either create the event objects yourselves and dispatch them manually.

Here's a longer version with a working example.

$('button').click(function() {
        var myEvent = document.createEvent('KeyboardEvent');
        myEvent.initKeyboardEvent('keyup', true, true, null, false, 
                                false, false, false, 76, 0);
        $('input').each(function() {
            this.dispatchEvent(myEvent);
        });
    });

Or you could look at jQuery simulate plugin which makes it slightly easier. Here's a shorter version with another working example.

$('button').click(function() {
    $('input').simulate('keyup');
});
