similar to: Rails/Ajax/File::Tail?

I could experiment to figure this out, but maybe the work has been done so I''m going to ask. Using Ajax, if I wanted to preload several (20) small (<1K) images, behind the scenes... would I... 1 - Queue the loading of the images with Ajax one at a time, asynchronously, and ignore the completion results. Would this result in the image being in the browser''s cache even if

But my question is how I should incorporate this into my actual app. In my app, the table I want to use this AJAX on belongs_to another table. I have one main controller in the app,

I just ran into this very problem myself. Yes, this is a bug in prototype. If you look in the code you will see that the relevent handlers and callbacks simply aren''t called with a synchronous request (onComplete is similarly not called). I submitted a patch <http://dev.rubyonrails.org/ticket/4657> over at dev.rubyonrails.org which fixes this behavior. If you decide to check it

Hello, I have a small class where i want to use attributes of the instance when an ajax call returns, so I wrote: *var* MyClass = Class.create(); MyClass.prototype = { initialize: *function*(form_id, rendered_id) { this.form_id = form_id; *var* edit_form = $(form_id); *var* rendered_node = $(rendered_id); *if* (!edit_form || !rendered_node) { this.enabled = *false*;

I''ve only tested this in Firefox so far, but it seems handy. One more way to let people know that stuff is going on behind the scenes. var SomeAjax = new Ajax.Request("/some/address", { onCreate: function() { document.body.parentNode.style.cursor = "progress" }, onComplete: function() { document.body.parentNode.style.cursor = "default" } }) --

Hello. I am building full-ajax back-end, which consits of many quite big partials. As the system grows up, performance is problem. After every click, partial is refreshed, if needed. I am now at 0.5 sec / request. I tried to simply disable ajax and the result was quite suprising: the same page is rendered over 2x faster. I update 80% of page in case of ajax.

I am trying to figure out if I should learn some node.js or

I was just working on a project where I needed to use Ajax.Updater with a synchronous request. It appears like all one would need to do is set the asynchronous option to false. I tried this and noticed that the content was being requested synchronously but the content was never injected into the DOM tree like one would expect from Ajax.Updater. In order to get the content returned by

Hi list, In one of my previous projects I had to satisfy the requirement of handling browser back- and forward calls within an Ajax application. Thus I didn''t get an urge to switch the JS part of this project to an other framework like dojo (which supports Browser history handling out-of-the-box), I had to come up with an idea of doing this with prototype/scriptaculous. The arisen

At the end of the long-running server process the results are downloaded as a separate file.
