- * Behaviors are event-triggered actions that attach to page elements,

- * {@link Drupal.behaviors} object using the method 'attach' and optionally
- * also 'detach'.
- *
- * {@link Drupal.attachBehaviors} is added below to the `jQuery.ready` event
- * and therefore runs on initial page load. Developers implementing Ajax in

- * been loaded, feeding in an element to be processed, in order to attach all
- * behaviors to the new content.
- *
- * Behaviors should use `var elements =
- * $(context).find(selector).once('behavior-name');` to ensure the behavior is
- * attached only once to a given element. (Doing so enables the reprocessing
- * of given elements, which may be needed on occasion despite the ability to
- * limit behavior attachment to a particular element.)

- * @example
- * Drupal.behaviors.behaviorName = {

- *
- * Such implementations should use `.findOnce()` and `.removeOnce()` to find

- * do anything simply in response to the element being moved, but because
- * IFRAME elements reload their "src" when being moved within the DOM,
- * behaviors bound to IFRAME elements (like WYSIWYG editors) may need to
- * take some action.
- * - `'serialize'`: When an Ajax form is submitted, this is called with the
