var touchStartPoint
Page({
  pageTouchStartHandler: function (e) {
    // 记录开始时的坐标
    touchStartPoint = e.changedTouches[0].pageX
  },
  pageTouchEndHandler: function (e) {
    // 当前触摸点坐标
    var currentTouchPoint = e.changedTouches[0].pageX  

    // 左滑
    if (currentTouchPoint - touchStartPoint < -50) {
      this.setData({
        sideBarStyle: 'transform:translate(0)'
      })
    }
    // 右滑
    if (currentTouchPoint - touchStartPoint > 50) {
      this.setData({
        sideBarStyle: 'transform:translate(300px)'
      })
    }
