Hi I want to trigger a XMLHttpRequest when the selected index change of a drop down box. What''s the best way to handle this? I''m sure I could figure out what javascript call link_to_remote is making and just wire that up to the drop down box, but I''m just wondering if there is a preferred or built in rails way to do this. Is there?

The documentation for it even use a drop down box as its example.

Frederick Thanks for point out remote_function. I''ll go read about it. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

I just tried it out, very cool, but not what I need. I need the drop down ochange to post the whole form, and then I need to stick the results into an html element inside the form. I think I can figure it though. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Ok...I can better explain the problem now
remote_function is generating an AJAX.Update like this:
new Ajax.Updater(''tune_in_link_1'',
''/my_account/tune_in/update_tune_in_link?channel_id=1'',
{asynchronous:true, evalScripts:true, parameters:Form.serialize(this)})
I need an Ajax.Updater like this:
new Ajax.Updater(''tune_in_link_1'',
''/my_account/tune_in/update_tune_in_link?channel_id=1'',
{asynchronous:true, evalScripts:true,
parameters:Form.serialize(this.form)})
Note the difference in parameters:Form.serialize. It has to be
this.form, not this. this evaluates to a select box, this.form evaluates
to the form that select box lives on, and I need that is what I need
serialized.
Is this something I have control over with the ajax helpers, or am I
supposed to build the javascript myself?
Thanks.

Ok...I got it. I''m not sure if this is the right way, but it works. I
added this to the remote_function options
:with =>
"Form.serialize($(''tune_in_form_#{c.id}''))"
