You must know the attachEvent can only put a function to be a
element's event handler, andd in that function "this" should be the
element itself, but the internet explorer linked it with window
object, and Event.observe doesn't fix this bug, same as $ input's name
bug, I think the Prototype library should fix it, my modification:
.....
_observeAndCache: function(element, name, observer, useCapture) {
if (!this.observers) this.observers = [];
if (element.addEventListener) {
this.observers.push([element, name, observer, useCapture]);
element.addEventListener(name, observer, useCapture);
} else if (element.attachEvent) {
var f=function(){observer.call(element,window.event)};// this line I
add
this.observers.push([element, name, f, useCapture]);
element.attachEvent('on' + name, f);
}
},
.........
use closure to fix this bug, I think this should be added into
Prototype, any ideas?
