Rails 3.2, JQuery, Javascript for Observe_field equivalent

Observe_field was available in Rails 2.X BUT removed in Rails 3.X. Need to code equivalent function in JQuery (used in Rails 3.2).

This is the (Rails 2.X) 'observe_field' in the project view:

{:action => 'add_material', :id => @[url removed, login to view]} do |form| -%>


{ :action => :find_cas_number, :project_id => @[url removed, login to view] },

:frequency => [url removed, login to view],

:update => :material_info,

:with => 'cas_number' %>

As user types cas_number into the input form, the program checks if the cas_number is already in the MySQL database, and if it is, then its (cas number) other attributes (also in the database, same table) will be displayed below it. Simplified Rails Program available for complete code.
