      currentValue: '',
      options: [],
    }
  },
  mounted() {
    if (!this.codeid) return
    //调用后端接口
    getDictItemByDictCode(this.codeid).then(res => {
      this.options = []
      res.data.forEach((value1,) => {
        const option = {value: value1.itemCode, label: value1.itemName}
        this.options.push(option)
      })
    })
