案例測試：
function TouchLeft(){ var startX, startY, moveEndX, moveEndY, X, Y; $(".howPlay,.xqing").on("touchstart", function(e) { // e.preventDefault(); startX = e.originalEvent.changedTouches[0].pageX, startY = e.originalEvent.changedTouches[0].pageY; }); $(".howPlay,.xqing").on("touchmove", function(e) { // e.preventDefault(); moveEndX = e.originalEvent.changedTouches[0].pageX, moveEndY = e.originalEvent.changedTouches[0].pageY, X = moveEndX - startX, Y = moveEndY - startY; if ( Math.abs(X) > Math.abs(Y) && X > 0 ) { //從左側向右滑動 $(".playback,.qingback").trigger("click"); } }); }
TouchLeft();
