It is * complicated, thus this doc is long and (hopefully) detailed enough to answer * your questions. * * If you need to react to the mouse wheel in a predictable way, this code is * like your bestest friend. * hugs * * * As of today, there are 4 DOM event types you can listen to: * * 'wheel' -- Chrome(31+), FF(17+), IE(9+) * 'mousewheel' -- Chrome, IE(6+), Opera, Safari * 'MozMousePixelScroll' -- FF(3.5 only!) (2010-2013) -- don't bother! * 'DOMMouseScroll' -- FF(0.9.7+) since 2003 * * So what to do? The is the best: * * normalizeWheel.getEventType(); * * In your event callback, use this code to get sane interpretation of the * deltas. This code will return an object with properties: * * spinX -- normalized spin speed (use for zoom) - x plane * spinY -- " - y plane * pixelX -- normalized distance (to pixels) - x plane * pixelY -- " - y plane * * Wheel values are provided by the browser assuming you are using the wheel to * scroll a web page by a number of lines or pixels (or pages). Values can vary * significantly on different platforms and browsers, forgetting that you can * scroll at different speeds. Some devices (like trackpads) emit more events * at smaller increments with fine granularity, and some emit massive jumps with * linear speed or acceleration. * * This code does its best to normalize the deltas for you: * * - spin is trying to normalize how far the wheel was spun (or trackpad * dragged). This is super useful for zoom support where you want to * throw away the chunky scroll steps on the PC and make those equal to * the slow and smooth tiny steps on the Mac. Key data: This code tries to * resolve a single slow step on a wheel to 1. * * - pixel is normalizing the desired scroll delta in pixel units. You'll * get the crazy differences between browsers, but at least it'll be in * pixels! * * - positive value indicates scrolling DOWN/RIGHT, negative UP/LEFT. This * should translate to positive value zooming IN, negative zooming OUT. * This matches the newer 'wheel' event. * * Why are there spinX, spinY (or pixels)? * * - spinX is a 2-finger side drag on the trackpad, and a shift + wheel turn * with a mouse. It results in side-scrolling in the browser by default. * * - spinY is what you expect -- it's the classic axis of a mouse wheel. * * - I dropped spinZ/pixelZ. It is supported by the DOM 3 'wheel' event and * probably is by browsers in conjunction with fancy 3D controllers .. but * you know. * * Implementation info: * * Examples of 'wheel' event if you scroll slowly (down) by one step with an * average mouse: * * OS X + Chrome (mouse) - 4 pixel delta (wheelDelta -120) * OS X + Safari (mouse) - N/A pixel delta (wheelDelta -12) * OS X + Firefox (mouse) - 0.1 line delta (wheelDelta N/A) * Win8 + Chrome (mouse) - 100 pixel delta (wheelDelta -120) * Win8 + Firefox (mouse) - 3 line delta (wheelDelta -120) * * On the trackpad: * * OS X + Chrome (trackpad) - 2 pixel delta (wheelDelta -6) * OS X + Firefox (trackpad) - 1 pixel delta (wheelDelta N/A) * * On other/older browsers.. it's more complicated as there can be multiple and * also missing delta values. * * The 'wheel' event is more standard: * * http://www.w3.org/TR/DOM-Level-3-Events/#events-wheelevents * * The basics is that it includes a unit, deltaMode (pixels, lines, pages), and * deltaX, deltaY and deltaZ. Some browsers provide other values to maintain * backward compatibility with older events. Those other values help us * better normalize spin speed. Example of what the browsers provide: * * | event.wheelDelta | event.detail * ------------------+------------------+-------------- * Safari v5/OS X | -120 | 0 * Safari v5/Win7 | -120 | 0 * Chrome v17/OS X | -120 | 0 * Chrome v17/Win7 | -120 | 0 * IE9/Win7 | -120 | undefined * Firefox v4/OS X | undefined | 1 * Firefox v4/Win7 | undefined | 3 * */ Utils.normalizeWheel = function (event) { var PIXEL_STEP = 10; var LINE_HEIGHT = 40; var PAGE_HEIGHT = 800; // spinX, spinY var sX = 0; var sY = 0; // pixelX, pixelY var pX = 0; var pY = 0; // Legacy if ('detail' in event) { sY = event.detail; } if ('wheelDelta' in event) { sY = -event.wheelDelta / 120; } if ('wheelDeltaY' in event) { sY = -event.wheelDeltaY / 120; } if ('wheelDeltaX' in event) { sX = -event.wheelDeltaX / 120; } // side scrolling on FF with DOMMouseScroll if ('axis' in event && event.axis === event.HORIZONTAL_AXIS) { sX = sY; sY = 0; } pX = sX * PIXEL_STEP; pY = sY * PIXEL_STEP; if ('deltaY' in event) { pY = event.deltaY; } if ('deltaX' in event) { pX = event.deltaX; } if ((pX || pY) && event.deltaMode) { if (event.deltaMode == 1) { pX *= LINE_HEIGHT; pY *= LINE_HEIGHT; } else { pX *= PAGE_HEIGHT; pY *= PAGE_HEIGHT; } } // Fall-back if spin cannot be determined if (pX && !sX) { sX = (pX < 1) ? -1 : 1; } if (pY && !sY) { sY = (pY < 1) ? -1 : 1; } return { spinX: sX, spinY: sY, pixelX: pX, pixelY: pY }; }; /** * https://stackoverflow
