selectedFn(e) {
        let target = e.target
        this.selectIndex = target.getAttribute('data-index')
        if (this.selectIndex === '1' && this.sort !== 'top') {
          this.orderField = 'salesVolume_i'
          this.order = 'asc'
          this.sort = 'top'
        } else if (this.selectIndex === '1' && this.sort !== 'bottom') {
          this.orderField = 'salesVolume_i'
          this.order = 'desc'
          this.sort = 'bottom'
        } else if (this.selectIndex === '2' && this.sort !== 'top2') {
