设置format="yyyy-MM-dd" 无效
<DatePicker v-model="formData.time" type="datetimerange" format="yyyy-MM-dd" placeholder="会员的开始和结束时间" style="display: block" placement="bottom-end"></DatePicker>
加上 @on-change="formData.time=$event"
<DatePicker @on-change="formData.time=$event" v-model="formData.time" type="datetimerange" format="yyyy-MM-dd" placeholder="会员的开始和结束时间" style="display: block" placement="bottom-end"></DatePicker>
