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