*
|
69 |
* Behaviors are event-triggered actions that attach to page elements, enhancing
|
70 |
* default non-JavaScript UIs. Behaviors are registered in the Drupal.behaviors
|
71 |
* object using the method 'attach' and optionally also 'detach' as follows:
|
72 |
* @code
|
73 |
* Drupal.behaviors.behaviorName = {
|
74 |
* attach: function (context, settings) {
|
75 |
* ...
|
76 |
* },
|
77 |
* detach: function (context, settings, trigger) {
|
78 |
* ...

79 |
* }
|
80 |
* };
|
81 |
* @endcode
|
82 |
*
|
83 |
* Drupal.attachBehaviors is added below to the jQuery ready event and so
|
84 |
* runs on initial page load. Developers implementing AHAH/Ajax in their
|
85 |
* solutions should also call this function after new page content has been
|
86 |
* loaded, feeding in an element to be processed, in order to attach all
|
87 |
* behaviors to the new content.
|
88 |
*
|
89 |
* Behaviors should use
|
90 |
* @code
|
91 |
* $(selector).once('behavior-name', function () {
|
92 |
* ...
|
93 |
* });
|
94 |
* @endcode
|
95 |
* to ensure the behavior is attached only once to a given element. (Doing so
|
96 |
* enables the reprocessing of given elements, which may be needed on occasion
|
97 |
* despite the ability to limit behavior attachment to a particular element.)
|
98 |
*
|
99 |
* @param context
|
100 |
* An element to attach behaviors to. If none is given, the document element
|
101 |
* is used.
|
102 |
* @param settings
|
103 |
* An object containing settings for the current context. If none given, the
|
104 |
* global Drupal.settings object is used.

* - unload: (default) The context element is being removed from the DOM.
|
140 |
* - move: The element is about to be moved within the DOM (for example,
|
141 |
* during a tabledrag row swap). After the move is completed,
|
142 |
* Drupal.attachBehaviors() is called, so that the behavior can undo
|
143 |
* whatever it did in response to the move. Many behaviors won't need to
|
144 |
* do anything simply in response to the element being moved, but because
|
145 |
* IFRAME elements reload their "src" when being moved within the DOM,
|
146 |
* behaviors bound to IFRAME elements (like WYSIWYG editors) may need to
|
147 |
* take some action.
|
148 |
* - serialize: When an Ajax form is submitted, this is called with the
|
149 |
* form as the context. This provides every behavior within the form an
|
150 |
* opportunity to ensure that the field elements have correct content
|
151 |
* in them before the form is serialized. The canonical use-case is so
|
152 |
* that WYSIWYG editors can update the hidden textarea to which they are
|
153 |
* bound.
