There are scenarios when it's important to know which element is gaining focus. Currently it's impossible to find out which element is going to get the focus within a blur() or focusout() event handler. Thus, I suggest to add a "EventTarget relatedTarget" property to the UIEvent class... a) pointing to the element which gains focus within blur() and focusout() events, b) pointing to the element which has lost focus within focus() and focusin() events. Moreover, an event sequence policy should be defined, stating the focus() will immediately follow blur() and focusin() will immediately follow focusout(). Currently, Google Chrome and Apple Safari enqueue focusin() *after* focusout() has returned. This causes other events to intercept these two events (e.g. a call to setTimeout(..., 0). This should not be possible. Calling element.focus() within a blur() event handler should update the target for the enqueued focus() event but not re-enqueue the focus() event. Same for focusin()/focusout(). Axel Dahmen www.axeldahmen.de
