Understanding Drupal Javascript Behaviors - buildamodule.com

In this video, we cover Drupal javascript behaviors. Drupal behaviors are a fantastic set of tools and techniques that are essential to developing dynamic AJAX applications in Drupal. They ensure that actions are associated with new content as it is loading on the page, either from vanilla javascript or from the server in an AJAX request.

Behaviors solve a problem that is difficult to approach without help from Drupal, and they're relatively easy to implement. After watching this video, you will understand the components required to add behaviors to a module, and will have some solid examples to work from.
