Rails - Oct 2009 - problem with RJS, params and Internet Explorer

Hi,

I have some RJS code to update my select fields. It perfectly works on
Firefox, but IE don''t want to send params to controller.

Here is the code in view:

<%= select("incident","service_group_id",
@service_groups,{:selected =>
0},{
  :onchange => remote_function(
    :update => "incident_service_id",
    :url => {:action => :update_services},
    :with => "''service_group_id='' + this.value")
}) %>

So in Firefox I have following params for ex.:
 {"action" => "update_services", "controller"
=> "incidents",
"service_group_id" => "2"}

But in IE:
 {"action" => "update_services", "controller"
=> "incidents"}

Tested on ruby 1.8, rails 2.3.4, Firefox 3.5, Internet Explorer 6,7,8

Hope, u help me

Are you sure that this.value is the way of access a select control
current value? Probably IE access it in a different way (as usual)
I''d strongly recommend you to access the value using Prototype or
jQuery or whatever JS library you''re using.

There''s no place like ~

When I''m doing like this:
  :onchange => remote_function(
    :update => "incident_service_id",
    :url => {:action => :update_services},
    :with => "''service_group_id='' +
alert(this.value)")
IE shows write option value...

I''m using Prototype. So could u show me how to access this value by 
Prototype library.

I''m not using Prototype since a while ago, but I think this should
work.
http://api.prototypejs.org/dom/form/element.html#getvalue-class_method
(API docs are your friend.)

<%= f.select("service_group_id", @service_groups,{:selected =>
0},{
  :onchange => remote_function(
    :update => "incident_service_id",
    :url => {:action => :update_services},
    :with => "''service_group_id='' +
$F(''incident_service_group_id'')")
  }) %>

I''d tried this way, but effect is the same, IE doesn''t
transfer params
and FF does

Did you try teh getValue() method?
try this:
    :with => "''service_group_id='' +
$(''incident_service_group_id'').getValue())

It seems to me the promlem is not in JS, cause I can get select value 
from page by any method.

In my opinion the problem in transfer ":with => " value in IE

Could it be concerned with session & cookies? I noticed that, when I 
switch authorization off, onchange event works even in IE

Here is the auth system:

---------------------------------------------------------------
class ApplicationController < ActionController::Base
  helper :all
  include NtlmSystem

  private
...
  def user_required
    if !logged_in?
      redirect_to(''/login'')
    end
  end

  def logged_in?
    if session[:logged_in].nil? || session[:logged_in] == :false
      return false
    end
    return true
  end
...
end

---------------------------------------------------------------

class UsersController < ApplicationController
  before_filter :user_required, :except => :login

  def login
    samaccountname = request.env[''REMOTE_USER'']
    cookies[:session] = session
    if samaccountname.nil?
      session[:logged_in] = :false
      render :file => "#{RAILS_ROOT}/public/403.html", :layout
=> false,
:status => 403
      return
    end
    samaccountname.sub!(/OU\\/,"")
    @user = User.find(:first,:conditions => ["samaccountname = 
?",samaccountname])
    if @user.nil?
      session[:logged_in] = :false
      render :file => "#{RAILS_ROOT}/public/403.html", :layout
=> false,
:status => 403
      return
    end
    session[:current_user] = samaccountname
    session[:user_id] = @user.id
    session[:logged_in] = :true
    redirect_to session[:http_referer]
  end
...
end

---------------------------------------------------------------

For NTLM authentication Mongrel_NTLM plugin used

Could it be problem here?
