callback registry
Locked
 
|
Hi there,
is there a way to clean up the callback registry, or to unregister some callbacks? The reason i ask is when you have a webpage that works almost only via Ajax and like never does normal callbacks, you end up with a very long callback registry that has a lot of blocks that are probably never called. If you don't pay attention to the kind of objects that you reference in such a callback, you might very well end up having memory leaks. It's a tricky problem, but maybe someone knows how to approach it.

Note that you can easily do a full refresh through AJAX. Just trigger an AJAX request to a normal callback, extract the string between <body> and </body> and place it into the DOM tree. This recreates all the callbacks in the page and ensures that old ones eventually expire. To the outside this "full request" feels like a normal AJAX action, just that it is maybe a bit slower than the other ones. Actually I planned to write a blog entry about this technique, just didn't find the time yet.

Hi Lukas,
thanks for the reply. Could you please tell me a bit more about the details, especially on the client-side javascript?

Hi,
I tried to insert the script in a seaside application, in the #updateRoot: method like this: updateRoot: root super updateRoot: root. root javascript resourceUrl: 'http://www.prototypejs.org/assets/2008/9/29/prototype-1.6.0.3.js' . root javascript add: '$(document.body).observe("click", function (event) { var element = Event.element(event); var extractor = /]*>((.|\s)*)<\/body>/; if (!element.href) element = element.up("a"); if (element.href) { new Ajax.Request(element.href, { method: "get", requestHeaders: [ "X-Requested-With", "" ], onSuccess: function (transport) { document.body.innerHTML = extractor.exec(transport.responseText)[1]; } }); Event.stop(event); } }.bindAsEventListener());' but it seems that I did not succeed. Am I doing something wrong? Cheers and thanks Marco On Oct 24, 2008, at 8:42 PM, Lukas Renggli wrote: >> thanks for the reply.

You need to add the code to the load script (#addLoadScript:),
otherwise the DOM is not ready yet.
