(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 * */ function normalizewheel( /*object*/ event ) /*object*/ { // reasonable defaults var pixel_step = 10; var line_height = 40; var page_height = 800; var sx = 0, sy = 0, // spinx, spiny px = 0, py = 0; // pixelx, pixely // 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 ) { // delta in line units px *= line_height; py *= line_height; } else { // delta in page units 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 }; } if (s.params.mousewheelcontrol) { /** * the best combination if you prefer spinx + spiny normalization. it favors * the older dommousescroll for firefox, as ff does not include wheeldelta with * 'wheel' event, making spin speed determination impossible. */ s.mousewheel.event = (navigator.useragent.indexof('firefox') > -1) ?
