Allow vertical scrolling on a horizontal iScroll (touch only)

vertical-enable.iscroll.js

var point, pointStartX, pointStartY, deltaX, deltaY;
var scroller = new iScroll('scrollerId', {
    vScroll: false,
    vScrollbar: false,
    hScrollbar: false,
    snap: 'li',
    momentum: false,
    onBeforeScrollStart: function(e) {
        point = e.touches[0];
        pointStartX = point.pageX;
        pointStartY = point.pageY;
        null;
    },
    onBeforeScrollMove: function(e) {
        deltaX = Math.abs(point.pageX - pointStartX);
        deltaY = Math.abs(point.pageY - pointStartY);
        if (deltaX >= deltaY) {
            e.preventDefault();
        } else {
            null;
        }
    }
});

Thanks. This solution helped me to resolve lot of problems related snapping.

Hi, my friends.

Could you share with me an aproximation adapted to iScroll 5? My problem is "scroll" event doesn't allow to receive the "e" param, and with the renamed event "beforeScrollStart", I can't determine the real direction because in this event these values are always 0,0.
I can get the real direction only on "scroll" and "scrollEnd" events, but I can't stop the propagation or prevent the default behaviour of the scrolling, so when my finger try to move the page in vertical direction, as It's formed of various iScrollers, I only get by clicking on a non-iScolll zone.

Thanks so much!

hello
i found a native solution to allow vertical scroll with iScroll 5 : http://lab.cubiq.org/iscroll5/demos/event-passthrough/
source code :

myScroll = new IScroll('#wrapper', { eventPassthrough: true, scrollX: true, scrollY: false, preventDefault: false });
