By default the prototype.js gives us the function /* prevent memory leaks in IE */ Event.observe(window, ''unload'', Event.unloadCache, false); But there is no unload event in out application as the content of the div keeps changing using the Ajax.Updater function. To handle such a scenario, we''ve added the following lines of code to prototype.js /* prevent memory leaks in IE */ Event.observe(window, ''un...

...all the observers before I lose them. Unfortunately, the Event.observe calls were written as inline anonymous functions so, when calling Event.stopObserving, I'm supposed to pass in a reference to the observer function, but it isn't able to be referenced as far as I know. I'd use Event.unloadCache() as a brute-force solution, but there are a ton of other observers for other areas of the page that would all have to be re-created. Is there a way around this (keeping the 'observers' as anonymous functions), or a better way to approach this? (Why do these things always crop up the nigh...

One of the Mozilla developer released a new extension to detect JS memory leaks: https://addons.mozilla.org/firefox/2490/ If it''s accurate, it might be bad news for Prototype. I have some code using prototype 1.4 with no leaks, but other code with 1.5 leaks on every single bindAsEventListener call, and a bunch of other places. Not sure if it''s just me; I may just be

Hello, I have a treeview, that works with scriptaculous in order to load the nodes dynamically. I also have in the main part of the page, a table with the list of elements. The lists of elements can be drag-dropped on the treeview in order to move them around (they are also draggable on other parts of the page) I need though, to refresh the treeview to reflect changes when a folder was moved

Just wondering why Event.stopObserving() doesn''t remove the itself from the Event.obervers array?

I''m sure there is an easy way to do this, but it is one of those things that is incredibly difficult to search for. How can I disable an ''Ajax.Autocompleter'' element from working ''on the fly''? I have a page where I''m using two (I know it''s crazy) Ajax.Autocompleter elements and once one of them has got a result I want the other field
