Just to make the second proposal easier to understand:
// abstract __proto__
var AbstractEventHandler = {
// invoked when events are fired
handleEvent: function (e) {
var
events = this.events,
type = e.type
;
if (events.hasOwnProperty(type)) {
events[type].call(this, e);
}
},
// shortcut to drop events
cancelEvent: function (e) {
(e.currentTarget || document).removeEventListener(
e.type, this, e.eventPhase !== e.BUBBLING_PHASE
);
}
};
// generic "class"
function WhateverUIClass(){}
// extends AbstractEventHandler
WhateverUIClass.prototype = Object.create(
WhateverUIClass.prototype,
{
// extends AbstractEventHandler
handleEvent: {value: AbstractEventHandler.handleEvent},
cancelEvent: {value: AbstractEventHandler.cancelEvent},
// implements events
events: {value: {
"click": function (e) {
console.log(this instanceof WhateverUIClass, e.type, e.eventPhase);
// to remove the event, if necessary
this.cancelEvent(e);
}
}}
}
);
document.addEventListener("click", new WhateverUIClass, false);
document.addEventListener("click", new WhateverUIClass, true);
Best Regards
