1.首先引入jquery和FlexoCalendar.js，和FlexoCalendar.css

<link href="/css/FlexoCalendar.css" type="text/css" rel="stylesheet">

<script src="https://cdn.bootcss.com/jquery/3.2.1/jquery.min.js"></script>
<script type="text/javascript" src="/js/FlexoCalendar.js"></script>

2.初始化周历

 $("#calendar-weekly").flexoCalendar({type: 'weekly', today: false, allowDate: ["2019-12","2020-02"]});

以上是初始化周历，taype是指定日历、周历或月历，allowDate是允许选择的日期范围；
具体介绍请参考文档；
说明一下，这里的allowDate文档上说的不是很容易懂。

文档截图
最后一句话不是很容易懂，这里我举个栗子，假设我们需求是要求可选时间范围是2019年12月到2020年2月份；那我们应该传入

 $("#calendar-weekly").flexoCalendar({type: 'weekly', today: false, allowDate: ["2019-11","2020-03"]});
//以我的理解是allowDate数组的第一项到第二项之间的月份是可选的，并且不包括这两个月份（即开区间）；

3.原js中有个小bug，这里我已经修复

具体问题可以参考bug原因及修复；

4.原项目中显示本月第几周，我改成了显示为本年度第几周。

原来如下图示：

现在改为下图所示：

同是去掉了所在月份，修改的代码中已经注释掉了，如果这里需要改回来显示月份的话，只需取消注释然后注释掉下一行即可。

5.下面直接上代码
