<Select
                  :label-in-value='true'
                  @on-change='choosePartyOther(index,$event)'
                  v-model="item.enterpriseName"
                  filterable
                  remote
                  :remote-method="remoteMethod3"
                  :loading="loading3">
                  <Option v-for="(option, index) in options1" :value="option.value" 
                  :key="index">{{option.label}}</Option>
              </Select>   

比如上面这样，这是用的iview里的select
