1、Date中的月份默认是从0开始，可以通过date.getMonth() + 1获取当前对应月份；
2、使用date.getDay()获取的是当前在本周内的第几天，获取当前日期值可以通过date.getDate()获取
具体如下：
this.month = (appointDate.getMonth()+1).toString();
this.day = appointDate.getDate().toString();
const hourStr = appointDate.getHours().toString();
const minuteStr = appointDate.getMinutes().toString();<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>
