Drupal.Behaviors
2 likes3,642 views
The document discusses Drupal behaviors and how they differ from traditional jQuery. Behaviors allow JavaScript to be attached to specific contexts, like HTML loaded via Ajax, and are re-attachable. Behaviors are defined using Drupal.behaviors and a behavior name, then attached to the DOM using Drupal.attachBehaviors. This allows behaviors to work across page loads and overrides, and attaches them only to needed contexts.
