Rails - Jul 2005 - Auto-complete box delay

The auto-complete box seems to delay until the user stops typing to pop 
up the complete box. I really prefer the box to pop up as the user types 
like Google Suggest. I found that changing line 83 of controls.js from

this.options.frequency    = this.options.frequency || 0.4;
to
this.options.frequency    = this.options.frequency || 0.01;

removes the delay. I''m assuming this causes it to hit the server much 
more often, but that''s no problem in my situation. It seems the proper 
way would be to pass in the frequency param in the options. Is there 
someway to do that from Rails? And also, aside from more hits on the 
server is there some reason for that delay? It feels MUCH better without it.

Thanks.

Frequency is a bit of a misnomer here (and the indentation in the code 
where it''s used is confusing). The value is used as a timeout to 
determine when the user has stopped/paused typing. When you set it very 
small, effectively the tiny delay between keypresses is considered as a 
pause. As the JavaScript code checks if the field has been changed, at 
worst you''ll get one AJAX request per keypress.

I haven''t tested it, but this small change in javascript_helper.rb
might
just do it

  def auto_complete_field(field_id, options = {})
# ...
    js_options = {}
    js_options[:frequence] = options[:frequency].to_s if 
options[:frequency]
# ...
  end
