Very similar to the JScrollPane * which does vertical scrolling, 2 features in particular have been added. * * 1) Intervals * 2) Resizing * * 1) Intervals can be added by attaching a class type of "scroll-interval" to any * element wrapped within the jscrollhorizontalpane context. This provides * the following abilitiies: * a) When dragging, it will snap to the closest element on release of dragger. * b) Mousewheel motions jump between intervals * c) Notches appear by default on the scrollbar, but can be overriden by css. * * 2) Resizing Also occurs. When turned on, all widths are dealt in percentages, so on a * screen refresh, the scroller will resize itself based on it's initial percentage. * There are a ton of different circumstances that need to be accounted for, and i'm sure * it's not meeting some people's expected behaviour so let me know about any problems or * feature requests for that! The resizing is done through the WResize plugin. * * * @example jQuery(".scroll-pane").jScrollHorizontalPane(); * * @name jScrollHorizontalPane * @type jQuery * @param Object settings hash with options, described below. * scrollbarHeight - The height of the generated scrollbar in pixels * scrollbarMargin - The amount of space to leave on the side of the scrollbar in pixels * wheelSpeed - The speed the pane will scroll in response to the mouse wheel in pixels * showArrows - Whether to display arrows for the user to scroll with * arrowSize - The height of the arrow buttons if showArrows=true * animateTo - Whether to animate when calling scrollTo and scrollBy * dragMinWidth - The minimum width to allow the drag bar to be * dragMaxWidth - The maximum width to allow the drag bar to be * animateInterval - The interval in milliseconds to update an animating scrollHorizontalPane (default 100) * animateStep - The amount to divide the remaining scroll distance by when animating (default 3) * maintainPosition- Whether you want the contents of the scroll pane to maintain it's position when you re-initialise it - so it doesn't scroll as you add more content (default true) * resize - Whether or not to have resizing turned on or not. * minimumWidth - The minimum width to allow the jScrollHorizontalPane to be resized to. Only effective when resize is on. * reset - When set to 'true' all the global properties will be reset. This is useful for dynamic refreshes on the page. * @return jQuery * @cat Plugins/jScrollHorizontalPane * @author Threeformed Media ( www.threeformed.com, info@threeformed.com ) * @version 1.0.0 */ var _jscr_originalSizes = new Array(); var _jscr_differenceSizes = new Array(); var _jscr_previousWindowSize = new Array(); var _jscr_originalPercentages = new Array(); var _jscr_intervals = new Array(); var _jscr_trackInt = new Array(); var _jscr_originalPos = new Array(); var _jscr_globalProperties = new Array(); jQuery.jScrollHorizontalPane = { active : [] }; jQuery.fn.jScrollHorizontalPane = function(settings) { settings = jQuery.extend( { scrollbarHeight : 10, scrollbarMargin : 5, wheelSpeed : 18, showArrows : false, arrowSize : 10, animateTo : false, dragMinWidth : 1, dragMaxWidth : 99999, animateInterval : 100, animateStep: 3, maintainPosition: true, resize: true, minimumWidth: 200, reset: false }, settings ); return this.each( function() { if(settings.reset == true) { jQuery.fn.jScrollHorizontalPane.reset(); } //This holds each one of the intervals, defaulting with one at the beginning. var $this = jQuery(this); var mouseWheelNext = 0; var mouseWheelMove = false; var currentId = $this.attr('id'); if(currentId == undefined) { currentId = $this.attr('class'); } var previousWindow = _jscr_previousWindowSize[currentId]; _jscr_originalPos[currentId] = -1; _jscr_globalProperties[currentId] = settings; _jscr_previousWindowSize[currentId] = $(window).width(); //On initial load, set values needed for percentage resizing. if(_jscr_originalSizes[currentId] == undefined) { //ie6 hack, since jquery width doesnt get the right value on an inproper refresh if((jQuery.browser.msie) && (parseInt(jQuery.browser.version) == 6)) { var outerWidth = parseInt($this.outerWidth()) - parseInt($this.offset().left); _jscr_differenceSizes[currentId] = $this.offset().left / $(window).width(); } else { var outerWidth = $this.outerWidth(); _jscr_differenceSizes[currentId] = $this.position().left / $(window).width(); } percentageWidth = (outerWidth / $(window).width()); _jscr_originalPercentages[currentId] = percentageWidth; _jscr_originalSizes[currentId] = $(window).width(); } else { percentageWidth = _jscr_originalPercentages[currentId]; diff = _jscr_differenceSizes[currentId] - (($this.offset().left + _jscr_originalPos[currentId])/ $(window).width()); percentageWidth = percentageWidth + diff; } var halfIntervals = new Array(); _jscr_intervals = new Array(); halfIntervals[0] = 0; _jscr_intervals[0] = 0; margin = $this.position().left; offset = 1; if(margin < 0) { margin = 0; } //Handles interval code $(".scroll-interval", $this).each( function(i, elem) { pos = $(elem).position().left - margin; if(pos != 0) { _jscr_intervals[i+offset] = pos; } else { offset--; } } ); if(_jscr_intervals.length <= 1) { _jscr_intervals = new Array(); } if (jQuery(this).parent().is('.jScrollPaneContainer')) { var currentScrollPosition = settings.maintainPosition ? $this.offset({relativeTo:jQuery(this).parent()[0]}).left : 0; var $c = jQuery(this).parent(); var paneWidth = $c.outerWidth(); var paneHeight = $c.innerHeight(); var rightPos = $this.offset().left + _jscr_originalPos[currentId] + paneWidth; if((previousWindow != $(window).width()) && ((rightPos > $(window).width()) || (previousWindow < $(window).width())) && (settings.resize == true)) { if($(window).width() >= _jscr_originalSizes[currentId]) { paneWidth = ($(window).width() * percentageWidth); } else { //Give the outside edge a 10 px buffer margin paneWidth = $(window).width() - ($this.offset().left + _jscr_originalPos[currentId]) - 10; } if(paneWidth < settings.minimumWidth){ paneWidth = settings.minimumWidth; } jQuery(this).parent().css( { 'height':paneHeight+'px', 'width': paneWidth + 'px' } ); } var trackWidth = paneWidth; if($c.unmousewheel) { if($.browser.opera) { $c.unbind("mousewheel", fn = function() { }); } else { $c.unmousewheel(); } } jQuery('>.jScrollPaneTrack, >.jScrollArrowLeft, >.jScrollArrowRight', $c).remove(); $this.css({'left':0}); _jscr_originalPos[currentId] = -1; } else { var currentScrollPosition = 0; this.originalPadding = $this.css('paddingTop') + ' ' + $this.css('paddingRight') + ' ' + $this.css('paddingBottom') + ' ' + $this.css('paddingLeft'); this.originalSidePaddingTotal = (parseInt($this.css('paddingLeft')) || 0) + (parseInt($this.css('paddingRight')) || 0); var paneWidth = $this.outerWidth(); var rightPos = $this.offset().left + _jscr_originalPos[currentId] + paneWidth; if((rightPos) > $(window).width()) { paneWidth = $(window).width() * percentageWidth; } if(paneWidth < settings.minimumWidth){ paneWidth = settings.minimumWidth; } var paneHeight = $this.innerHeight(); var trackWidth = paneWidth; $this.wrap( jQuery('
