I have a table with a collection select object that I am looking
update the selectedIndex of using links on the page
<%= collection_select(:machine, :user_id, @users, :id, :fullname,
{:include_blank => true}, html_options = {:onChange => remote_function
(:update => "ajaxmessage", :url => {:action =>
''update_machine_user'',
:controller =>
''manage_machines'',:id=>@machine.id},:with=>"''users_id=''+this.value")})
%>
Currently the links look like:
]<% if @machine.user_id != session[:user_id] %>
<%= link_to(image_tag(''user_add.png''),
{:action =>
''update_machine_user'', :id => @machine,
:users_id=>session[:user_id]},
{:border => 0, :title => "Edit Details", :class =>
"image_link"}) %>
<%else%>
<%= link_to(image_tag(''user_reset.png''),
{:action =>
''update_machine_user'', :id => @machine, :users_id=>nil},
{:border =>
0, :title => "Edit Details", :class => "image_link"})
%>
<%end%>
Although they work they do a screen refresh of course since its not
Here is the controller used.
def update_machine_user
@machine = Machine.find(params[:id])
@machine.user_id = params[:users_id]
#flash.keep[:notice] = "User ID #{params[:user_id]}"
@machine.save
#flash[:notice] = ''User updated!!!''
redirect_to session[:last_list]
end
Can anyone give me some ideas of how to ajaxify this to update the DOM
element.
Thanks

The problem is that is the collection select object is repeated in a
table of objects so this ID appears multiple times. To deal with it I
created a <form id ="#{machine.fqdn}"> .... collection_select
object </
form> around each of these and tried to refer to them using $("#
{machine.fqdn}").machine_user_id.selectedIndex=whatever, but the
prototype $() function does not seem to want to take a variable. It
seems to work with a static id, but not a variable one. Any ideas how
this could be done?
Thanks

Instead of creating that form with that special id, why not give that id to the select box ? The $ function is just a regular function - it doesn''t care whether its argument is a literal, a function call or something else. Regardless, ''.machine_user_id'' is not how you would find the child of a certain element. If you want the child of an element matching a given css selector use the down function.

Is there a way to tell collection_select to use a specific ID then
other than machine_user_id. That is what I was originally trying to
do so I did not have to go down into the object from the form .
I was trying to get around it by using a call to a form $("#
{machine.fqdnj}").machine[user_id].selectedIndex= and it did not seem
to work. When I was trying this with a standard html setup with
prototype I found that it would not accept a variable being passed
into $() but if I set the name using a static name it seemed to work.
