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
知识点：js
自定义标签方法
-------------
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
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
