You want to use either function#call() or function#apply....
Definitions (from https://developer.mozilla.org/)
function#call():
Calls a function with a given *this *value and *arguments * provided
individually.
$('aDiv').morph('background:#00ff00; width:300px;', {
afterFinish:callExample.call(this, 'aString')
});
function callExample(szStr){
console.log(szStr);
}
function#apply()
Calls a function with a given *this *value and *arguments *provided as an
array
$('aDiv').morph('background:#00ff00; width:300px;', {
afterFinish:applyExample.apply(this, ['aString', 'test'])
});
function applyExample(){
console.log(arguments);
}
Or Prototype's Function#bind()
$('aDiv').morph('background:#00ff00; width:300px;', {
afterFinish: bindExample.bind(this, 'aString')
});
function bindExample(){
console.log(arguments);
}
I noticed you're alert()'ing your debugging output... i would recommend
using FireBug.
