各位大佬，帮帮忙。我不管是splice删除单个数组数据，还是全部上传完清空，当我再返回该页面时，刚才清空的数据（console.log确实没显示了）又来了。怎么办啊，有没有好心人帮我看看，最好我把微信小程序代码发给你，你帮我看看，我没有积分，不甚感激。
//获取删除事件，是哪一张发票
    var dataset = e.currentTarget.dataset;
    var Index = dataset.index;
    //that.data.list.splice(Index,1);
    wx.showModal({
      title: '提示',
      content: '确定要删除此发票吗',
      success: function (res) {
        if (res.confirm) {
          console.log('点击确定了');
          console.log(that.data.requestDataArray)
          //删除该张发票
          that.data.requestDataArray.splice(Index, 1);
          that.data.orderInfologs.splice(Index, 1);
          that.setData({
            requestDataArray: that.data.requestDataArray,
          })
          that.setData({
            orderInfologs: that.data.orderInfologs,
          })

 that.setData({
            orderInfologs:{}
          })
          that.setData({
            orderInfo:''
          })
         
          wx.clearStorageSync('orderInfologs')
          console.log(that.data.orderInfologs)
