Thank for the reply but me being new and bit dumb couldn't make use of
it. I searched for the onChange listener in Rails but couldn't find.
Also I couldn't figure out how I can use the remote_function that you
suggested. I have made my one combo box as:
<form>
<%=select("selected","location",GreatWalk.getAvailableLocations)%)
</form>
In the controller:
def self.getAvailableLocations
@locations=GreatWalk.find(:all)
@locationhoder=[]
for locs in @locations
@locationholder<<[locs.location,locs.location]
end
@locationholder
end
So, plz guide me thru... thnx.
