使用laydate组件 创建年度，季度，月，日期，半年度的选择

效果：

业务需求：有一个年、季、月、日、半年度 的选择；用户选择年时，日期只能选择年，选择季度时日期只能选择年季度，选择月时只能选择年月，选择日时能选择年月日。这样根据用户选择，动态更换日期插件的限制

代码解释：这里的业务是取周期范围的，如果只需要一个日期，初始化这个插件时range 属性去掉就是一个的。在取日期值的时候一样也要考虑范围，起始时间与结束时间是年月季拼凑后面的日期是有区别的，起始时间拼选择年月的01号，结束日期为选择日期的最后一天，代码已经处理好了这一块，精确计算当前月最后一天为28,29,30,31，天，代码里都有详细体现。如果你只需要一个日期，那就直接拼最后一天就好了。不需要考虑起始日期结束日期这些东西了。最主要的是季度和半年度，laydate并没有提供这些，这些东西需要我们自己实现。

环境搭建

1.下载官方laydate并解压/
2.找到解压之后的laydate.js文件，将内容整体替换为下面的提供的js代码。
