370 * Attach all registered behaviors to a page element.
371 *
372 * Behaviors are event-triggered actions that attach to page elements, enhancing
373 * default non-JavaScript UIs. Behaviors are registered in the Backdrop.behaviors
374 * object using the method 'attach' and optionally also 'detach' as follows:
375 * @code
376 *    Backdrop.behaviors.behaviorName = {
377 *      attach: function (context, settings) {
378 *        ...
379 *      },
380 *      detach: function (context, settings, trigger) {
381 *        ...
382 *      }
383 *    };
384 * @endcode
385 *
386 * Backdrop.attachBehaviors is added below to the jQuery.ready event and
387 * therefore runs on initial page load. Developers implementing Ajax in their
388 * solutions should also call this function after new page content has been
389 * loaded, feeding in an element to be processed, in order to attach all
390 * behaviors to the new content.
391 *
392 * Behaviors should use
393 * @code
394 *   var elements = $(context).find(selector).once('behavior-name');
395 * @endcode
396 * to ensure the behavior is attached only once to a given element. (Doing so
397 * enables the reprocessing of given elements, which may be needed on occasion
398 * despite the ability to limit behavior attachment to a particular element.)
399 *
400 * @param context
401 *   An element to attach behaviors to. If none is given, the document element
402 *   is used.
403 * @param settings
404 *   An object containing settings for the current context. If none is given,
405 *   the global Backdrop.settings object is used.

433 *   is used.

438 *   A string containing what's causing the behaviors to be detached. The
439 *   possible triggers are:
440 *   - unload: (default) The context element is being removed from the DOM.
441 *   - move: The element is about to be moved within the DOM (for example,
442 *     during a tabledrag row swap). After the move is completed,
443 *     Backdrop.attachBehaviors() is called, so that the behavior can undo
444 *     whatever it did in response to the move. Many behaviors won't need to
445 *     do anything in response to the element being moved, but because IFRAME
446 *     elements reload their "src" when being moved within the DOM, behaviors
447 *     bound to IFRAME elements (like WYSIWYG editors) may need to take some
448 *     action.
449 *   - serialize: When an Ajax form is submitted, this is called with the
450 *     form as the context. This provides every behavior within the form an
451 *     opportunity to ensure that the field elements have correct content
452 *     in them before the form is serialized. The canonical use-case is so
453 *     that WYSIWYG editors can update the hidden textarea to which they are
454 *     bound.
