vue2  computed实现

  computed: {
    FBAAddressListComputed () {
      if (!this.fbaInput) return this.FBAAddressList

      const lowerCaseInput = this.fbaInput.toLowerCase()

      return this.FBAAddressList.filter((item) => {
        return [item.fbaCode, item.zipCode, item.countryCode, item.state, item.city,             
            item.address].some(
          (field) => field && field.toLowerCase().indexOf(lowerCaseInput) !== -1
        )
      })
    },
  },

vue3 通过 watch 实现搜索 

  watch(fbaInput, newV => {
    if (fbaInput.value === '') {
      searchFbaList.value = FBAAddressList.value
      return
    }

    const lowerCaseInput = fbaInput.value.toLowerCase()
    searchFbaList.value = FBAAddressList.value.filter(item => {
      return [item.fbaCode, item.zipCode, item.countryCode, item.state, item.city,             
        item.address].some(
        field => field && field.toLowerCase().indexOf(lowerCaseInput) !== -1
      )
    })
  })
