An Event object created with $.Event() constructor doesn't match the actual jQuery Event object

[gryzzly]

Creating an event with $.Event() constructor for keyboard events doesn't normalize event object in a consistent way. I.e. created object doesn't have "which" property - and an event created by actual keypress does.

Tested in Chrome 11.0.696.57, Safari 5.0.4 (6533.20.27), Firefox 4.0.1 and Opera 11.10 b. 2092 on Mac OS X 10.6.7

Well the whole idea is that if you're creating a fake event, you'll do a good job of faking the data you need from the event object. In your example, what exactly should which be? We don't know the button you're trying to fake, there is absolutely no information we can use to determine it.

We don't know the button you're trying to fake, there is absolutely no information we can use to determine it.

$(document).trigger($.Event('keypress', { 
    keyCode: 64 
}))

As far as I know and have used for quite a while, which == keycode when e.keycode isn't available:

var which = e.keyCode || e.which; // this is the code I've been using for some time

Hence when I create jQuery.Event object I expect it to normalize keyCode to become .which, just as it does for the real events.

Ah, okay, I see what you're saying. Sorry! We're not calling jQuery.event.fix on those events. But...doing so might have some serious performance implications. We definitely would only want to do this if someone provided the second arg to Event.

For now I'm inclined to leave it as-is, rwaldron and I have been talking about a better way to to jQuery.event.fix that may be in 1.7.

Sure thing, thanks.

Though calling jQuery.event.fix() directly on this event didn't help either – see ​http://jsfiddle.net/gryzzly/5aDv2/5/

As dmethvin mentions we're likely to keep this as-is for the time being due to performance risks and we haven't yet defined a better way to address this on the 1.7 roadmap during discussions, I'll be closing this ticket as patchwelcome.

Should a member of the team wish to reopen and continue the discussion at a point in the future, please feel free to.
