Modals typically are popup dialogs, + * notices, modal windows, and image containers. An expando ("_jqm") containing + * the UUID or "serial" of the modal is added to each element. This expando helps + * reference the modal's settings in the jqModal Hash Object (jQuery.jqm.hash) + * + * Accepts a parameter object with the following modal settings; + * + * (Integer) zIndex - Desired z-Index of the modal. This setting does not override (has no effect on) preexisting z-Index styling (set via CSS or inline style). + * (Integer) overlay - [0-100] Translucency percentage (opacity) of the body covering overlay. Set to 0 for NO overlay, and up to 100 for a 100% opaque overlay. + * (String) overlayClass - This class is applied to the body covering overlay. Allows CSS control of the overlay look (tint, background image, etc.). + * (String) closeClass - A close trigger is added to all elements matching this class within the modal. + * (Mixed) trigger - An open trigger is added to all matching elements within the DOM. Trigger can be a selector String, a jQuery collection of elements, a DOM element, or a False boolean. + * (Mixed) ajax - If not false; The URL (string) to load content from via an AJAX request. + * If ajax begins with a "@", the URL is extracted from the requested attribute of the triggering element. + * (Mixed) target - If not false; The element within the modal to load the ajax response (content) into. Allows retention of modal design (e.g. framing and close elements are not overwritten by the AJAX response). + * Target may be a selector string, jQuery collection of elements, or a DOM element -- but MUST exist within (as a child of) the modal. + * (Boolean) modal - If true, user interactivity will be locked to the modal window until closed. + * (Boolean) toTop - If true, modal will be posistioned as a first child of the BODY element when opened, and its DOM posistion restored when closed. This aids in overcoming z-Index stacking order/containment issues where overlay covers whole page *including* modal. + * (Mixed) onShow - User defined callback function fired when modal opened. + * (Mixed) onHide - User defined callback function fired when modal closed. + * (Mixed) onLoad - User defined callback function fired when ajax content loads. + * + * @name jqm + * @param Map options User defined settings for the modal(s). + * @type jQuery + * @cat Plugins/jqModal + */ +$.fn.jqm=function(p){ +var o = { +zIndex: 3000, +overlay: 50, +overlayClass: 'jqmOverlay', +closeClass: 'jqmClose', +trigger: '.jqModal', +ajax: false, +target: false, +modal: false, +toTop: false, +onShow: false, +onHide: false, +onLoad: false +}; + +// For each element (aka "modal") $.jqm() has been called on; +// IF the _jqm expando exists, return (do nothing) +// ELSE increment serials and add _jqm expando to element ("serialization") +// *AND*... +return this.each(function(){if(this._jqm)return;s++;this._jqm=s; + +// ...
