vue依据下拉框选择其余信息

下拉框选择内容后，其余input框与该下拉框相关的内容实时回显,用@change=加方法

<el-row>
          <el-col :span="12">
            <el-form-item label="选择站点" prop="resourcesId">
              <el-select v-model="form.resourcesId" @change="updateInput" placeholder="请选择要申请的站点">
                <el-option v-for="item in tableList" :key="item.id" :label="item.stationName" :value="item.id"
                  :disabled="item.status == 1"></el-option>
              </el-select>
            </el-form-item>
          </el-col>
          <el-col span="12">
            <el-form-item label="租金" prop="amount">
              <el-input v-model="form.amount" placeholder="请输入租金" />
            </el-form-item>
          </el-col>
        </el-row>
        <el-row>
          <el-col span="12">
            <el-form-item label="开始日期" prop="beginTime">
              <el-date-picker clearable v-model="form.beginTime" type="date" value-format="yyyy-MM-dd"
                placeholder="请选择租金开始日期">
              </el-date-picker>
            </el-form-item>
          </el-col>

change方法内容,tableList是数据数组

updateInput() {
      const selectedStationId = this.form.resourcesId;
      const selectedStation = this.tableList.find(item => item.id === selectedStationId);
      if (selectedStation && selectedStation.rent) {
        this.form.amount = selectedStation.amount;//租金
        this.form.beginTime = selectedStation.endTime;//时间
        // console.log(selectedStation.amount);
      } else {
        this.form.amount = '';
      }
    },
