I know this is a bug / behavior in Internet Explorer, but I was hoping
that a fix could be put into Prototype to make it work. I've tried
doing it myself based on some code I found, but I'm having problems
getting it working so I need some help.
The problem is that Internet Explorer will call functions that are
attached to the same element and event type in random order instead of
the order in which they were added. For example, if I register the
following functions:
Event.observe(window, 'load', blah1);
Event.observe(window, 'load', blah2);
Event.observe(window, 'load', blah3);
the functions can be called in any order in IE. So, a likely solution
would be to call one function that calls all the other functions in
order. So here was the code I found that someone suggested (the
changed parts are commented out):
Object.extend(Event, {
...
observers: false,
_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) {
this.observers.push([element, name, observer, useCapture]);
//element.attachEvent('on' + name, observer);
element.attachEvent('on' + name, this._observeIE);
}
},
//Added
_observeIE: function(e) {
Event.observers.each( function(observer) {
if (e.srcElement ==
observer[0])
observer[2].call(this, e);
}.bind(this) );
},
...
stopObserving: function(element, name, observer, useCapture) {
element = $(element);
useCapture = useCapture || false;
if (name == 'keypress' &&
(navigator.appVersion.match(/Konqueror|Safari|KHTML/)
|| element.detachEvent))
name = 'keydown';
if (element.removeEventListener) {
element.removeEventListener(name, observer, useCapture);
} else if (element.detachEvent) {
try {
//element.detachEvent('on' + name, observer);
element.detachEvent('on' + name, this._observeIE);
} catch (e) {}
}
}
});
The problem with this is... it never calls any of my functions. So I
took a look at e.srcElement inside _observeIE with an alert, and it's
saying that's e.srcElement is null. I don't know why. So I thought,
maybe window events have a null for their source element, but that
wasn't the case; it's null for every event on every element.
So hopefully someone has some suggestions.
Thanks,
Matt
