Rails spinoffs - Nov 2006 - Script.aculo.us : how to use updateElement function of Ajax.Autocompleter ?

Hello,
i''ve tried this :

new Ajax.Autocompleter("nom", "autocomplete_choices",
"getLogin.php", {
minChars: 2,  indicator: ''indicator1'', updateElement :
getLogin});
-----
<script >
function getLogin(valeur){
    $("debug").innerHTML=valeur;
}
</script>


The list is well populating but when I select an item, to run the
getLogin function here is what i get in my debug div :  [object]

What am i doing wrong ?
Thanx for your help

OK, first, you do know that redefining updateElement will *replace*
regular option tokenizing and addition with your own, right?  Is this
really what you''re trying to do?  The argument that is passed is the
HTMLOptionElement representing the selected item.
The default updateElement behavior performs all the processing described
in the wiki: filtering based either on the select option or by excluding
"internal"-class''d elements, then text concatenation, then
either value
addition (defined ''token'' option) or value replacement.  And
of course,
calling the callback I mention in the next paragraph.  That''s a LOT to
redefine properly, don''t you think?
If you''re just looking for a callback function to be called once the
selection was properly performed and has appeared in your autocompleted
field, use the afterUpdateElement callback.  It takes two arguments: the
autocompleted field and the HTMLOptionElement representing the selected
item.
