Dependencies

Needs jQuery, Modernizr

How to

class="yaah-js": Bind the event to the desired element data-ya-href: Link to the content to insert (can be href if the element is an anchor)

Options

Triggers: data-ya-trigger

• always: Always trigger the request (default)
• once: Trigger the request one time only
• submit: Submit Form in AJAX with serialized data
• autoload: Autoload the request on DOMReady
• manual: Triggered manually when bind the associated event

Location: data-ya-location

• replace Replace the target element
• after: Insert after the target element
• before: Insert before the target element
• inner: Replace the content inside the target element
• top: Insert at the beginning of the target element
• bottom: Insert at the end of the target element
• remove: Remove the target element

Target: data-ya-target

• #CSS .Selector: Can be whatever CSS Selector you like but most of the time you'll want it unique. If empty, clicked element.

Redirect data-ya-redirect

• http://path/to/url: Redirect after AJAX to the url (page reload)

Stop event propagation data-ya-nopropagation

• true: Stop event propagation on click. Useful if you don't want to trigger parent events.

Confirm data-ya-confirm

• JavaScript! Do you speak it ?: Display the message in a confirm box, trigger AJAX on confirm only.

Url Update History data-ya-pushstate

• url/to/push: url to push to the history

AJAX Request Data data-ya-post

• serializedData: String of serialized data to pass to the AJAX request

AJAX Request Loop data-ya-timer

• time in seconds: Number of seconds between AJAX call

Events

Events are triggered to the element with the yaah-js class. Most of them are similar to regular XHR events:

• yaah-js_xhr_submit: event triggered on form submit just before data fetch
• yaah-js_xhr_manualTrigger: the event to trigger for "manual" trigger
• yaah-js_xhr_beforeSend: before the XHR is sent
• yaah-js_xhr_complete: XHR complete
• yaah-js_xhr_beforeInsert: XHR success, but before updating target with data
• yaah-js_xhr_success: XHR success, after target updated with data (please read below if .yaah-js element is in target)

For case where your .yaah-js element is in the target (and then, removed when data is updated), you might not be able to get the event catchable on any element with delegation, like that : $(document).on('yaah-js_xhr_success', '.yaah-js', …);

So, for this specific behavior, YAAH generates an unique event id sent in yaah-js_xhr_beforeInsert event, then triggered after the data update. Use it only if your element is in the target. Otherwise, you can juste use the yaah-js_xhr_success event

$(document.body).on('yaah-js_xhr_beforeInsert', '.yaah-js', function(e, eventId, target, item, data) {
	$(document).one(eventId, function(e, target, item, data){
		// do whatever you want in the target, with the target, or with the data.
	});
});
