我难

   // 弹窗询问是否打印标签
    async inlinePrint() {
      await this.$confirm('样品添加成功，是否打印标签？！', '提示', {
        confirmButtonText: '确定',
        cancelButtonTex: '取消',
        type: 'warning',
        callback: action => {
          if (action === 'confirm') {
            var printData = this.cellList.filter((this.checkBarcode))
            printData.forEach(this.deleteObj)
            var printDataC = this.setPrintArr(printData)
            this.sendRequest(printDataC)
          } else {
            this.$message({
              type: 'info',
              message: '已取消打印'
            })
          }
        }
      })
    },
    // 造打印数组
    setPrintArr(printData) {
      var printDataB = [
        {
          testBillNumber: '',
          testItem: '',
          nominalCapacity: '',
          serialNumber: '',
          barcode: '',
          proposer: ''
        }]
      debugger
      printDataB[0].testBillNumber = printData[0].testBillNumber
      printDataB[0].testItem = printData[0].testItem
      printDataB[0].nominalCapacity = printData[0].nominalCapacity
      printDataB[0].serialNumber = printData[0].serialNumber
      printDataB[0].barcode = printData[0].barcode
      printDataB[0].proposer = printData[0].proposer
      return printDataB
    },

这么点东西写了一上午

优化：
其实代码我自己可能都懒得看，说下优化的地方吧
1、去掉没必要的变量
2、造数组由删掉无用属性改为只拿有用的属性

  // 弹窗询问是否打印标签
    async inlinePrint() {
      await this.$confirm('样品添加成功，是否打印标签？！', '提示', {
        confirmButtonText: '确定',
        cancelButtonTex: '取消',
        type: 'warning',
        callback: action => {
          if (action === 'confirm') {
            var printData = this.setPrintArr(this.tempCell[0])
            this.sendRequest(printData)
          } else {
            this.$message({
              type: 'info',
              message: '已取消打印'
            })
          }
        }
      })
    },
    // 造打印数组
    setPrintArr(cellData) {
      var printData = [
        {
          testBillNumber: this.ManageList[0].testBillNumber,
          testItem: cellData.testItem,
          nominalCapacity: cellData.nominalCapacity,
          serialNumber: cellData.serialNumber,
          barcode: cellData.barcode,
          proposer: this.ManageList[0].proposer
        }]
      return printData
    },
