el-select点击选择后仍有rules提示问题

<el-form-item class="required" label="* 中标厂商" prop="bidsAddInfo.winBidCompany">         <el-select           v-model="bidsAddInfo.winBidCompany"           placeholder="请选择中标厂家"         >           <el-option             v-for="item in winBidCompany"             :key="item.situation"             :label="item.label"             :situation="item.situation"           >           </el-option>         </el-select>       </el-form-item>

rules: {         winBidCompany: [           { required: true, trigger: "change", message: "请输入中标厂家" },         ],       },

解决：prop和v-model要保持一致
