Convenience events for focusin/out etc with poor cross-brower support

[dominicwhittle]

Are there plans to polyfil any common events?
Theres some inconsistency in current browser input event listeners; eg focusin and focusout vs focus and blur etc

If not, then how about following jQuery's API in which you can spec multiple space-separated event types?

$el.on('focusin blur whatevs', 'input', callbackFn)
// ^ works in jQuery, not Cash

Event retooling is one of the biggest changes planned for the next version, mainly fixing some delegate support ( #114 ) and allowing for namespaces ( #121 ). Registering multiple events per callback/delegate shouldn't be a problem.

I'm not sure specifically what you mean by polyfilling common events. Are you referring to inconsistencies between browsers about when focusout is triggered versus blur?

Cool.

That's right. I was wondering if there were plans to account for some of the subtle inconsistencies in events that jQuery seamlessly irons out. I do appreciate that the size of Cash should be a major consideration in any feature like this; eg,

$(input).on('focusin', onFocus) // Chrome, Safari, IE
$(intput)[0].addEventListener('focus', onFocus, {useCapture: true}) // Firefox

function onFocus (e) { 
  // do stuff on focus 
}

Haven't specifically encountered these bugs. Is it only with focusin/focusout that you're having difficulty?

Seems like jQuery is mainly fixing focusin/focusout and blur:

With a few small fixes for click and load

It's not a bug so to speak, just that (as you say) focusin/focusout aren't supported in Firefox, so I'm having to resort to vanilla javascript to handle that via addEventListener. It's really not a big deal, but given this is an inconsistency in current browsers it might be worth considering "fixing" that browser inconsistency in Cash.

This is implemented as of v2.1.2.

Regarding ironing out differences between browsers, it sounds like a very difficult task to do properly (especially while still supporting IE9+), and the size of the bundle could increase substantially.

Closing as this shouldn't be an issue anymore since Firefox v52 (~13 versions ago).
