小编这次要给大家分享的是原生js如何实现日期选择插件,文章内容丰富,感兴趣的小伙伴可以来了解一下,希望大家阅读完这篇文章之后能够有所收获。

最近公司项目告一段落,想着写个小玩意打发下上班时间,就用js很粗糙的实现了下日期选择插件。间间断断历时1天多,实现了选择日期的功能,从写完的整体代码来看,耦合度还是蛮高的,我觉得还是我对js中的原型继承方式理解不深刻,一定有更优雅的方式再优化下这份粗糙的代码,各位前端小伙伴们在看完我的代码后请麻烦指出其中实现的不好的地方,有批评指正让我有动力继续写博客嘛!
先说下这个插件的功能:功能很简单,目前只实现了选择一个日期(当然可以赋初始值,默认是当前日期),选择跨月日期时,会有一个粗糙的动画效果,效果图如下:
然后,说下我写这个插件思路:
1.插件整体是以function Dt作为基类,通过choose方法调用,如:$('#txtDt').choose({value: '2018/8/1'});$方法用来选择要传入选择日期的文本控件。插件由head、content、foot3部分组成,head:选择上月、下月、昨日、明日和显示当前选择日期;centent:显示日期列表;foot:关闭
2.Dt中render方法会更新属性(年、月、日.....)
3.跨月实现的动画过渡主要通过content中的3个月列表(上月【隐藏】、当月、下月【隐藏】)分别替换来实现,比如显示下月,只需要将下月列表逐步移动到显示区域,将当月移动到上月,再将原上月列表删除,再将最新的下月列表插入到当月之后。思路很简单,小伙伴们看代码就能一目了然了。只是,我对自己实现的上月、下月、昨日和明日的方法很厌恶,代码严重耦合,美观性很差,如果有小伙伴有更好的解决办法,一定要告诉我。
话不多说,附上所有代码:
