Autocompleter question

["Bob Silva" <me (at) bobsilva.com>]

Hi Joe,

Using the afterUpdateElement patch for the Javascript Macro Helper, I do
this using the following code:

function auto_complete_on_select(element, selectedElement)
{
    document.getElementById('encounter_client_id').value = 
		selectedElement.childNodes.item(0).innerHTML;
}

Which gets called by:

<%= auto_complete_field 'client', :url => {:controller => 'clients', 
	:action => 'auto_complete_for_client'},
	:after_update_element => 'auto_complete_on_select', :select =>
'name' %>


And my LI looks like this:

<li><span class="informal">#{client.id}</span><span
class="select">#{client.name}</span></li>

In this case I use the new select class method and older informal style for
BC purposes.

Cheers,

Bob Silva

Hi,

You can play with <span class="informal"> which will be displayed, but not
selected and <span style="display:none"> which won't be displayed, but
selected.

You can do pretty much everything with that, so you won't need to moidfy
autocompleter code. 

Reagrds,
Nico

Hey all,
    When using the Ajax.autocompleter, how would I configure it so that the
user is searching based on an entry's name, but once they select an entry, I
record the ID?
 
    I have the user entering a person's name in a text box to make it easier
to find contacts in a large database.  I know that I can display content
that doesn't end up in the textbox by using the "informal" class, but how
can I associate the contact's ID with the LI item and have that value be
recorded into a hidden field when selected?
 
    Is there an easier way than just putting a hidden, non-standard
"contactId" attribute on my LI tags and then using the afterUpdateElement
option?
 
Thanks in advance,
Joe
