多选下拉框：解决下拉框远程查询回显展示不正确的问题

        <el-select style="width: 100%" 
          ref="testCode"
          v-model="dialogFormData.codes"
          multiple filterable remote 
          :remote-method="codesRemoteMethod">

            :value="item.value">
          </el-option>
        </el-select>

        // data: 从table中传给dialog的对应行数据row
      const { names, codes } = data
        // 解决远程展示value不是label的问题
        names.map((item, index) => {
        // 获取到对应的refs元素，然后往其中的cachedOptions去push对象，将需要回显对应的label与value值存入
          this.$refs.testCode.cachedOptions.push({
            currentLabel: item,
            currentValue: codes[index],
            label: item,
            value: codes[index]
          })
