So it's easy enough to pop some :onchange JavaScript code inline for a
collection_select drop-down list. That code adds value of what's
selected to a couple of other text fields:
<label for="venue_id">Place*:</label> <%=
collection_select(:event, :venue_id, @venues_all, :id, :name, {:prompt
=> " Please select a location"}, {:onchange => "var id = this.value;
document.forms[0].elements[2].value=(id);document.forms[0].elements[3].value=document.forms[0].elements[5].value"})
%>
But I don't want the venue value (id number) in the text fields; I
want venue.phone and venue.url in those fields. After numerous hours
the past few days, I still don't understand how I can mix JavaScript
and Ruby so I can access the venue.phone and venue.url values and have
them update my form's other text fields. Any advice appreciated.
