Modaal - accessible modals - v0.4.4 by Humaan, for all humans. http://humaan.com */ /** Modaal jQuery Plugin : Accessible Modals ==== General Options === type (string) : ajax, inline, image, iframe, confirm. Defaults to 'inline' content_source (stribg) : Accepts a string value for your target element, such as '#my-content'. This allows for when trigger element is an `` link. Not to be confused with the already existing `source` event. animation (string) : Fade, expand, down, up. Defaults to 'fade' after_callback_delay (integer) : Specify a delay value for the after open callbacks. This is necessary because with the bundled animations have a set duration in the bundled CSS. Specify a delay of the same amount as the animation duration in so more accurately fire the after open/close callbacks. Defaults 350, does not apply if animation is 'none', after open callbacks are dispatched immediately is_locked (boolean) : Set this to true to disable closing the modal via keypress or clicking the background. Beware that if type != 'confirm' there will be no interface to dismiss the modal if is_locked = true, you'd have to programmatically arrange to dismiss the modal. Confirm modals are always locked regardless of this option Defaults to false hide_close (boolean) : Set this to true to hide the close modal button. Key press and overlay click will still close the modal. This method is best used when you want to put a custom close button inside the modal container space. background (string) : Background overlay style. Defaults to '#000' overlay_opacity (float) : Background overlay transparency. Defaults to 0.8 overlay_close (boolean) : Set this to false if you want to disable click to close on overlay background. accessible_title (string) : Accessible title. Default 'Dialog Window' start_open (boolean) : Set this to true to launch the Modaal window immediately on page open fullscreen (boolean) : Set this to true to make the modaal fill the entire screen, false will default to own width/height attributes. custom_class (string) : Fill in this string with a custom class that will be applied to the outer most modal wrapper. width (integer) : Desired width of the modal. Required for iframe type. Defaults to undefined //TODO height (integer) : Desired height of the modal. Required for iframe type. Defaults to undefined //TODO background_scroll (boolean) : Set this to true to enable the page to scroll behind the open modal. should_open (boolean|function) : Boolean or closure that returns a boolean to determine whether to open the modal or not. close_text : String for close button text. Available for localisation and alternative languages to be used. close_aria_label : String for close button aria-label attribute (value that screen readers will read out). Available for localisation and alternative languages to be used. === Events === before_open (function) : Callback function executed before modal is opened after_open (function) : Callback function executed after modal is opened before_close (function) : Callback function executed before modal is closed after_close (function) : Callback function executed after modal is closed source (function(element, src)) : Callback function executed on the default source, it is intended to transform the source (href in an AJAX modal or iframe). The function passes in the triggering element as well as the default source depending of the modal type. The default output of the function is an untransformed default source. === Confirm Options & Events === confirm_button_text (string) : Text on the confirm button. Defaults to 'Confirm' confirm_cancel_button_text (string) : Text on the confirm modal cancel button. Defaults to 'Cancel' confirm_title (string) : Title for confirm modal. Default 'Confirm Title' confirm_content (string) : HTML content for confirm message confirm_callback (function) : Callback function for when the confirm button is pressed as opposed to cancel confirm_cancel_callback (function) : Callback function for when the cancel button is pressed === Gallery Options & Events === gallery_active_class (string) : Active class applied to the currently active image or image slide in a gallery 'gallery_active_item' outer_controls (boolean) : Set to true to put the next/prev controls outside the Modaal wrapper, at the edges of the browser window. before_image_change (function) : Callback function executed before the image slide changes in a gallery modal. Default function( current_item, incoming_item ) after_image_change (function) : Callback function executed after the image slide changes in a gallery modal. Default function ( current_item ) === AJAX Options & Events === loading_content (string) : HTML content for loading message. Default 'Loading …' loading_class (string) : Class name to be applied while content is loaded via AJAX. Default 'is_loading' ajax_error_class (string) : Class name to be applied when content has failed to load. Default is 'modaal-error' ajax_success (function) : Callback for when AJAX content is loaded in === SOCIAL CONTENT === instagram_id (string) : Unique photo ID for an Instagram photo. */ ( function( $ ) { var modaal_loading_spinner = '' var Modaal = { init : function(options, elem) { var self = this; self.dom = $('body'); self.$elem = $(elem); self.options = $.extend({}, $.fn.modaal.options, self.$elem.data(), options); self.xhr = null; // set up the scope self.scope = { is_open: false, id: 'modaal_' + ( new Date().getTime() ) + ( Math.random().toString(16).substring(2) ), source: self.options.content_source ?
