el-form表单el-form-item prop一次验证两个值

1.表单添加两个框，prop写上

<el-form :model="ruleForm" :rules="rules" ref="ruleForm" label-width="100px" >
<el-form-item type="type" label="时间" prop="dateSectOne">
							<div class="timeShijian">
								<el-time-picker :clearable="false" v-model="ruleForm.dateSectOne.first" placeholder="开始时间" value-format="HH:mm" format="HH:mm"></el-time-picker>
								<el-time-picker :clearable="false"  v-model="ruleForm.dateSectOne.second" value-format="HH:mm" placeholder="结束时间" format="HH:mm"></el-time-picker>
							</div>
						</el-form-item>
					</<el-form >

2.data里写,验证规则添加validator: this.validateFields

ruleForm: {
  dateSectOne:{first:'',second:'',},
},
rules: {
	dateSectOne: [
		{validator: this.validateFields, required: true, message: '请选择班次时间'},
	],
}

3.validateFields设置

validateFields(rule, value, callback) {
			// 在这里编写验证逻辑
			if (value.second && value.first) {
				callback();
			} else {
				callback(new Error('请选择时间'));
			}
		},
