I’m trying to use a autocomplete text field like the one showed in  
scriptaculous

[http://demo.script.aculo.us/ajax/autocompleter\_customized](http://demo.script.aculo.us/ajax/autocompleter_customized)

It works. But I want to call a javascript function just afterwards the  
users selects one name.

Is there any  
onselect=\>‘do\_something()’  
to use with text\_field\_with\_auto\_complete ?

Thanks

Christian

Yes, there’s:

:after\_update\_element =\> “function (e, v) { … }”

The first argument of the JavaScript function is the textfield  
element and so e.value holds the selection, v is the corresponding  
list item.
