Hi jon-2,
First, it's hard for me to give you advice here because I don't know what
your ultimate objective is, so instead I'll say this: Whenever you're
programming something that seems a bit hacky or convoluted, you are probably
going about it the wrong way. In this case, I guarantee you are trying to do
this the hard way.
First, when you use the Options class in your own classes,
options.onComplete is removed when you do this.setOptions(options), so this
statement won't work when called after you set the options. I'm guessing
you're doing this before that, though, or else you'd get an undefined error.
Secondly, MooTools offers you a way to add more than one function to an
event. Example:
var myReq = new Request({
onComplete: fn1
});
myReq.addEvent('complete', fn2);
//also, this works:
myReq.addEvent('onComplete', fn3);
There is no need to try and combine the functions yourself.
