I use this function (think I got it from Darron Schall's blog) to do a deep
copy. I had the same experience as Jesse with mx.utils.ObjectCopy not
working correctly...
// ----------------------------------------------
// copy an object
function copyObject(obj) {
// create a "new" object or array depending on the type of obj
var copy = (obj instanceof Array) ? [] : {};
// loop over all of the value in the object or the array to copy them
for(var i in obj) {
// assign a temporarity value for the data inside the object
var item = obj[i];
// check to see if the data is complex or primitive
switch(item instanceof Array || item instanceof Object) {
case true:
// if the data inside of the complex type is still complex,
we need to
// break that down further, so call copyObject again on that
complex
// item
copy[i] = copyObject(item);
break;
default:
// the data inside is primitive, so just copy it (this is a
value copy)
copy[i] = item;
}
}
return copy;
}
