Hi Fred,
Thanks for your response.
render :update
Ive got quite a few Ruby conditions and styling going in the js.erb
file im using now to display the contact information. And ive got more
possibilities than the 3 ive shown above in the controller. So this
might not be the right option for me. Right?
observe_field callback
This might work for me. Right now, the only callbacks I have on the
observe_field are showing and hiding the spinner. I have never written
custom callbacks on Rails JS helpers. Could you help me through this?
So im guessing I should be having something like this
<%= observe_field 'contact_id', :frequency => 0.5, :update =>
'info', :before => "Element.show('spinner')",
:success => "handle_contact_request(value);", :url =>
show_contact_path,:method =>:get,
:with => 'contact_id' %>
and in application.js
function handle_contact_request(value){
Element.hide('spinner');
if value=="new contact"
{
//how do i redirect to the New Contact page?
}
else
{
//show contact info. But how do I handle the conditions
and styling??
}
}
Am I getting the basic idea right? If yes, how can I handle the
conditional redirecting and the rest in Javascript?
Thanks again Fred.
