Settlement: function () {
    var that = this;
    console.log(that)
    console.log('99999')
    wx.request({
      url: app.d.ceshiUrl + '&action=product&m=Settlement',
      method: 'post',
      data: {
        cart_id: that.data.cartId, // 购物车id
        uid: that.data.userId, // 微信id
        num1: that.data.num1, //数量
        type: that.data.type, //(1.直接结算 0购物车结算)
      },
      header: {
        'Content-Type': 'application/x-www-form-urlencoded'
      },
      success: function (res) {
        var status = res.data.status;
        if (status == 1) {
          if (that.data.allow) {
            res.data.arr.coupon_money = Number(res.data.arr.coupon_money) - Number(that.data.allow);
          }

          }

            address: res.data.arr.adds, // 收货地址
            addrId: res.data.arr.adds.id ? res.data.arr.adds.id : '', // 收货地址id
            productData: res.data.arr.pro, // 商品信息
            total: res.data.arr.price, // 总价
            money: res.data.arr.money, // 优惠券金额
            coupon_money: Number(parseFloat(res.data.arr.coupon_money).toFixed(3).slice(0, -1)), // 优惠后金额

            freight: res.data.arr.yunfei ? res.data.arr.yunfei : 0, //运费
          });
          
          setTimeout(function () {
            that.setData({
              remind: false
            });
          }, 1000);
        } else {
          that.setData({
            remind: true
          });
          wx.showToast({
            title: res.data.err,
            icon: 'none',
            duration: 2000,
          });
          if (status == 0) {
            setTimeout(function () {
              util.getUesrBgplus(that, app, false)
              wx.navigateBack({
                delta: 1
              })
            }, 2000);

          } else {
            setTimeout(function () {
              util.getUesrBgplus(that, app, false)
              wx.navigateBack({
                delta: 1
              })
            }, 2000);
          }
        }
      },
      error: function (e) {
        wx.showToast({
          title: '网络异常！',
          duration: 2000
        });
      }
    });

  },

请问大家如何调用这个数据：
如我需要调用这个数据 total: res.data.arr.price, // 总价
注：我是需要在同这个JS页面中调用

[葉幺]

js中调用 写成this.total 页面中调用total
