Exact, an element removed may be add it elsewhere and my purpose is
out ....
It remains that the proposal of Mike
element.descendants (). invoke ( 'stopObserving');
element.stopObserving ();
But I find it rather heavy for the developer who must insert code to
delete each element and can also cause performance's problems.
Could not we consider making public the method _destroyCache and add
it an optional parameter "ancestor"?
Expl :
function destroyCache(ancestor) {
ancestor = $(ancestor);
for (var i = 0, length = CACHE.length; i < length; i++) {
if (!ancestor)
|| (CACHE[i].descendantOf // Possible on Window / Document
Elements
&& (CACHE[i].descendantOf(ancestor)
|| CACHE[i].match(ancestor))) {
Event.stopObserving(CACHE[i]);
CACHE[i] = undefined;
}
}
CACHE = CACHE.reject(Object.isUndefined);
}
This method could be integrated also at the AjaxUpdater before
replacing the content ?
