操作步骤：

        <uni-card is-full>  
            <text class="uni-h6">可以同时选择日期和时间的选择器</text>  
        </uni-card>  
        <uni-section :title="'日期时间用法：' + datetimesingle" type="line"></uni-section>  
        <view class="example-body">  
            <uni-datetime-picker type="datetime" v-model="datetimesingle" @change="changeLog" />  
        </view>  
    </view>  
</template>  
<script>  
    export default {  
        data() {  
            return {  
                datetimesingle: '',  
            }  
        },  

        watch: {  
            datetimesingle(newval) {  
                console.log('单选:', this.datetimesingle);  
            },  
        },  
        mounted() {  
            setTimeout(() => {  
                this.datetimesingle = Date.now() - 2*24*3600*1000  
            },3000)  
        },  

        methods:{  
            changeLog(e) {  
                console.log('change事件:', e);  
            },  
        }
