iview 日期控件转换格式yyyy-MM-dd

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>
