el-select绑定值为对象时校验必填失效问题记录

问题描述

el-select绑定对象实现分页下拉查询报销人功能，修改回显时清空报销人没有触发必填校验。

<el-form :inline="true" :rules="orderRules" ref="order" :model="order">
	<el-form-item label="报销人" prop="reimbursementPerson" class="form-item">
	    <el-select
	         v-model="order.reimbursementPerson"
	         filterable
	         remote
	         :remote-method="getReimperson"
	         @visible-change="visibleChange($event, 'getReimperson')"
	         @change="changePerson"
	         value-key="userId"
	         @clear="clearOptions('reimpersonOptions')"
	         clearable
	         placeholder="请选择报销人"
	         v-loadmore:getReimperson="{ data: reimpersonOptions }"
	     >
	         <el-option v-for="item in reimpersonOptions.list" :key="item.userId" :label="item.displayName" :value="{ userId: item.userId, displayName: item.displayName }">
	             <div slot>{{ item.displayName + '(' + item.userName + ')' }}div>
	         el-option>
	     el-select>
	 el-form-item>

解决方法

回显详情原写法代码，打印回显的信息如下：

清空报销人选择框，没有出现必填提示，点击提交按钮也没有出现必填提示而是直接调接口了

回显详情修改后写法，打印回显的信息如下：

清空报销人会出现提示
