兼容各大浏览器的触摸滑动(touchmove)事件

兼容各大浏览器的触摸滑动(touchmove)事件，说到底还是IE老东家的问题。

var touchStart = "touchstart";
var touchMove = "touchmove";
if (window.navigator.msPointerEnabled) {
 touchStart = "MSPointerDown";
 touchMove = "MSPointerMove";
}else if (window.navigator.pointerEnabled) {
 touchStart = "pointerdown";
 touchMove = "pointermove";
}
var me = $("#bar");
me.bind(touchStart, function (e, b) {
 if (e.originalEvent.pointerType === "touch" && e.originalEvent.pageY) {
 //e.originalEvent.pageY;
 } else if (e.originalEvent.touches && e.originalEvent.touches.length) {
 //e.originalEvent.touches[0].pageY;
 }
});

me.bind(touchMove, function (e) {
 if (e.originalEvent.pointerType === "touch" && e.originalEvent.pageY) {
 //e.originalEvent.pageY;
 } else if (e.originalEvent.touches && e.originalEvent.touches.length) {
 //e.originalEvent.touches[0].pageY;
 } 
});
me.parent().css({
 "-ms-touch-action": "pan-y pinch-zoom",
 "touch-action": "pan-y pinch-zoom"
 }); // 使用 pan-x （垂直划动） 或者 pan-y （水平划动）跟据实际情况而定。
