this.selectedValue.forEach((val) => {
          let auctionCompanyTemp = {}
          auctionCompanyTemp.companyCode = this.options2.filter(
            (vo) => vo.companyCode == val
          )[0].companyCode
          auctionCompanyTemp.companyName = this.options2.filter(

          )[0].companyName
          !this.companyJson.some(
            (item) => item.companyCode === auctionCompanyTemp.companyCode
          ) && this.companyJson.push(auctionCompanyTemp)
        })

基本去重

unique(arr) {
      const res = new Map()
      return arr.filter((arr) => !res.has(arr.xxx) && res.set(arr.xxx, 1))
    }
console.log(this.unique(response.DataList))
