How do you attach an event listener to watch for the user to change the selected option in a ''select'' field before they click the submit button in order to instruct the page to change (AJAX) based on what the user selected in the field. In other words, I want the page to be able to change when the user makes a selection from a form select before they ever click any button. Thank you.

I installed it and then wrote method: def on_prebooking_start_date_change render :update do |page| @current_two_months = two_months_starting( params[:dom_value].month, params[:dom_value].year) page.replace_html( "month_1", :partial => "month", :object => @current_two_months ) end end With the following view code: _rent.rhtml: <%= render(:partial => "month" , :object => @current_two_months) %> <%= start_form_tag :action => ''start_date'' %> <%= render(:partial => "prebooking_dates_selects") %> <%= submit_tag "Check Rate >" %> <%= end_form_tag %> _month.rhtml: <div id="month_1"> ...month 1 view html here...</div> and _pre_booking_dates_selects.rhtml: <!--[form:prebooking]--> <p><label for="prebooking_start_date">Start Date</label><br/> <%= date_select ''prebooking'', ''start_date'', :id => ''start_date'', :start_year => 2007, :end_year => Day.last_day.year, :order => [:month, :day, :year] %></p> <!--[eoform:prebooking]--> The on...change method above does nothing. ????

I even tried
def on_prebooking_start_date_change
render :update do |page|
page.insert_html(:after, ''start_date'', :inline =>
"<span>This is
working</span>" )
end
end
Just to see if it worked.
It doesn''t!
