similar to: Help with ajax and form submission

While working on a new application, a friend and I ran into what we think is a problem with using ajax. Users are used to being able to modify the contents of a screen until they are finished and then saving (committing). There does not seem to be a way to do this with ajax, since you have to modify the model whenever you call back to the server. The half baked solution that we came up with is

When I do remote form submits through jQuery .submit() why do I sometimes have to refresh the page manually to see the results? My jQuery handler is very simple: $("#vote_yes").click(function() { $("#approval").val(true) $(".edit_vote").submit() }); And the link that leverages this bit of code is as follows: <%= link_to("Vote

I''d bet money that they use a hidden iframe. Gmail already uses that to avoid breaking the back button, from what I''ve read. It''s impossible to send multipart form data through XMLHttpRequest, or so everything I read says and my own personal attempts confirm. There is an IE ActiveX plugin that will let you send files in a similar fashion, but it''s IE only. I

I''m new to RoR and have started building my first application. I''m building an account sign-up controller and I have two questions: 1. What is the best way to pass form params between methods in my sign-up controller? The solution I''m using seems too hacky and there''s got to be a something more elegant. I''m instantiating User.new to capture the

Hi! I try to get AJAX running on a mobile Windows Mobile 5.0 based device and failed. There should be a JavaScript support but nothing happens.

Does anyone know a good reference for the various statuses that XmlHttpRequest''s readyState property can have? I mean, I know what the states are, but I''m unclear on the circumstances under which each occurs... In a simple test I wrote, I''m seeing the loaded, interactive and complete states (i.e. my Ajax.Request instance calls its onLoaded, onInteractive and

Hi all. I ''m using Ajax request on my site and i need to show some message wneh AJAX call is running, (sometimes it happen so slow).

Hi, I''m writing an app that has some ajax-y content to it and am experiencing a weird error in Firefox (1.5.0.1) that doesn''t appear elsewhere (where ''elsewhere'' is IE6). I''ve basically taken the typo sidebar code and rewritten it for my needs. One of the things I''ve written is a ''sidebar'' that lists all the countries in

Try as I may, I cannot figure out how to make the :on option work with the observe field method. I have looked into the javascript that is eventually called, and it does not appear that there is any way to override which event is bound for which control. Any help would be greatly appreciated. Thanks -- Phil

Hi, I am looking for a solution to use ajax.request object. Return response text will be in xml format and I like to know how to parse that xml information, so that I can put those info into the "span" or "div" tags of my html page. Is there any easy way to parse that xml info using prototype library? Thanks, kevin. -- Posted via http://www.ruby-forum.com/.

Hi everyone, I''ve encountered a HUGE problem, which may not be RoR-oriented, but there might be a workaround somehow. See, at this moment, I''m unable to send AJAX requests back and forth when the information contains an ampersand (''&''). In essence, request is never completed. The odd thing is that it only happens with Firefox (IE and Opera works fine).

I really have no more input than that, so the subject speaks for itself. How do you test that AJAX effects shown in the browser are actually happening? Maybe an auto-complete form field is a good starting example. Sean

Has someone come up with a generic way to handle ajax requests that exceed a certain time? In my concrete case, I have several select boxes for drilling down a hierarchy. When the user clicks an option, the next deeper level is retrieved. To avoid multiple concurrent requests, I disable the select box. As the request may take too long or cause an error, I set a timeout that re-enables the

Hello everyone! I have a little problem with ruby on rails and ajax. I have 2 sort of droppable items, 2 drop_receiving_element areas working fine; but instead of updating a div, I would like to have a form submitted with an ajax call. got it? (not so easy to explain) My solution was to add a complete action submitting the form like this: <%= drop_receiving_element "list",

I''m not sure if this is even possible, but here is my current method: class Item < ActiveRecord::Base def self.generate(name) Item.create(:name => name) || nil end end class ItemController < ActionController::Base layout "application" def index @items = Item.find(:all) end def create if @request.method ==:post name = @params[:name]

Hello, I''m new to this Ajax thing but it''s perfect for a project of mine. But I can''t figure out how to best pass the form data. This is a text field that should be on every page of my application. In my layout, the form submission looks like this: <%= form_remote_tag :update => ''comment'', :url => { :controller =>

Hi, I''ve never posted here before so please forgive me if I''m not observing proper decorum, yadda yadda yadda :-) I''ve ran into a very, very strange bug with Prototype I wanted to share and see if anyone else has seen this. In a few of my projects involving Ext JS, I''m using the TreePanel control, which uses AJAX to load child nodes asynchronously. Because I

Hi all, I was wondering if one could pull a completely separate web site into a div, e.g. <a href="#" onclick="new Ajax.Updater(''artifact'', ''http://www.vivisimo.com/'', {asynchronous:true, evalScripts:true, onLoading:function(request){Toggle.display(''message2body'')}}); return false;">&raquo;</a> it fails

Ok, I''m missing something obvious but after some reasonable looking in _The_ Rails book (sorry haven''t gotten the cookbook yet) and these archives I don''t see a solution to my question. Question: What is the cleanest way to load a div via AJAX when the page loads - no user action necessary. I don''t really want to hack in a hidden remote form or link that is
