关于DATE--转化-->年月日

也可以通过CHOSEN_DATE=new Date().getFullYear()等等，各取出年月日，拼成年月日

datetime模块下有4个类

　　datetime.date---->年月日

　　datetime.time----->时分秒

　　datetime.datetime---->年月日时分秒

　　datetime.timedelta--->代表两个时间之间的时间差

日期加减

会议室预定demo

BUG1

使用时间插件跳转某日期，由于ajax，刷新页面导致date重新赋值一直是当前日期。

思路：直接取url的值http://127.0.0.1:8000/index/?book_date=2018-03-29
