I'm using 1.6.1rc3 to have access to Element.storage. I need to write
a function that deep clones an element and copies the Element.observe
events as well as the Element.Storage items with it. I've managed to
write the code that can copy one or the other.
The problem comes in when I try to do both (copy the storage items and
the events.) I suppose due to Event.observe using the Element.storage
item, I can't seem to have the items that I've stored with
Element.store to copy while maintaining the Event.observe events that
I've copied.
I can copy the observe events or the element.store events, but not
both. Below is some terrible code for review. Thanks for any help or
insults.
deepClone: function(element) {
//deep clone node
var newElement = element.clone(true); //clone the node
//stop observing because of IE BS
newElement.stopObserving();
//copy the item
var registry = Element.retrieve(element,
'prototype_event_registry');
if (!Object.isUndefined(registry)) {
registry.each( function(pair) {
var eventName = pair.key, responders = pair.value;
responders.each( function(r) {
Element.observe(newElement, eventName,
r.handler);
});
});
}
//for all of the descendants, copy the event handlers
var srcdecend = element.descendants();
var dstdecend = newElement.descendants();
var numdecend = srcdecend.length;
for(var i = 0; i < numdecend; ++i) {
//stop observing because of IE BS
dstdecend[i].stopObserving();
//copy the registry
var registry = Element.retrieve(srcdecend[i],
'prototype_event_registry');
if (!Object.isUndefined(registry)) {
registry.each( function(pair) {
var eventName = pair.key, responders =
pair.value;
responders.each( function(r) {
Element.observe(dstdecend[i],
eventName, r.handler);
});
});
}
}
return newElement;
}
