Hi there! I did implemented the radio button with remote_function to update some div via RJS. It works perfect with FireFox, but behaves weird with IE. When I click the radio button it loads data (I see the indicator showing) but not updates the div with info until I click left mouse button anywhere. It''s weird =( Here is the snippet from .rhtml code <td>

I''ve been trying for days now to figure this out on my own, but I can''t, so this is my cry for help. Here''s my situation: I need to update multiple <DIV> elements on a page, each with its own HTML, but I just can''t figure out how to get it to work. That is, I want to replace everything within each <DIV> element with something new. When I try what

I had one point in my project where I needed a synchronous Ajax call; in other words, I wanted the Ajax.Updater call to not return until the content of my page had been updated. However, I found that if you call Ajax.Updaterwith the {asynchronous: false} option, the onComplete() function would never be called and your content would not be updated. Was this the intended behavior? I added the

I have been using multiple observers, i.e., observe_field(), on the same input field and relying on them to execute in the same order that they appear in the page. This has been working fine in FireFox, but it does not seem to work in MSIE; the requests come in and are processed in a different order. Now, I''ve always been a little hesitant about using this technique, but it always

Hi! Wondering if anyone can tell me what''s wrong with my code? I''m trying to use the onChange event of a select list to update multiple divs... Agile Web Development with Rails (p. 403) suggests using ":complete => eval(request.responseText) instead of :update" I''ve attempted the following test code: # in the view <select name="plist",

I am using the update_element_function to update the text in some elements. This works fine, however, if I try to update an element that is not on the page anymore, it fails silently and no further javascript statements will be executed within that same request.responseText. Is there a way to fail gracefully in this scenario and ignore the missing elements? Thanks, Tom

I have a wizard which consists of two pages. To keep it simple let''s say that the first page asks the user to select a state from the drop down menu. In case the user doesn''t select any state, an error message needs to be displayed. Ideally I would like to do something like this. def new selected_value = params[:addevent][:state_id] if selected_value == "-1"

class Event < ActiveRecord::Base belongs_to :venue belongs_to :category end class Venue < ActiveRecord::Base belongs_to :city end class City < ActiveRecord::Base belongs_to :state end I want to retrieve all event records belonging to a state.

This

Hi, I am using evaluate_remote_response and update_element_function, to update elements with blocks of content, something like this: <% update_element_function("div_id", :binding => binding) do %> <div id="newdiv_id"> This is a new div! </div> <%= draggable_element(''newdiv_id'') %> <% end %> That will update the

Howdy, I''m a Rails beginner working on my first significant project with RoR. I''m trying to figure out how to validate a foreign key (you know, make sure the row actually exists.) However, validates_associated doesn''t seem to be what I want to use, nor does it work... -- BEGIN -- class City < ActiveRecord::Base has_many :schools belongs_to :state

I would like to have a login box setup so that if incorrect info is submitted, the box "shakes" via Effect.Shake. If the correct information is submitted, I want to redirect to some other page. The only solution I''ve found is the following, which is pretty ugly, as it displays the javascript I''m invoking on the page prior to the redirect. Here is the code: The Form

Hiall, Unfortunately I just can''t find out how to setup a default selected value when using collection_select. My call is like so: <%= collection_select(:consultant, :lastname, @consultants, :id, :lastname, { :selected => @current_consultant.id } ) %> which is not working, I debugged so far that I know that @current_consultant.id contains the correct value. Any tips? cheers

Hi everyone, I am writing a ruby on rails application, and making heavy use of AJAX calls and evaluate_remote_response. In my remote responses I often have several update_element_function calls going on, to update several divs on the page. What I am doing is calling update_element_function, with the content as a block. Inside the block I usually have html, or make calls to other partials or
