Question

I am working on Ruby on Rails application, with Prototype.
I want to display a loading div automatically with every ajax request and hide it on completion, without writing code for every ajax request in my application.
Is there anyway to do this.

<div id="loader">Loading...</div>

You may want to check out this article:

Basically you can handle it with:

  Ajax.Responders.register({
     onCreate : startLoading,
     onComplete : stopLoading
  });

Where startLoading and stopLoading are callback functions that show/hide your activity indicator.
