You can use e.originalEvent.gesture.deltaX to determine whether the end of is moving left or right compared to the beginning :

var deltaX = e.originalEvent.gesture.deltaX;
if (deltaX > 0) {
    // 右移
} else if (deltaX < 0) {
    // 左移
}

panleft and panright events are constantly triggered during the movement, and are judged to move left or right relative to the position last time was triggered. If you want to see whether
is moved left or right when ends compared to when begins
, then the above method is OK; If you want to see whether the panleft event or was triggered last panright event, then we can only monitor the panleft and panright events, but it seems impossible to monitor the panend
