本文实例讲述了jQuery实现的简单日历组件定义与用法。分享给大家供大家参考,具体如下:
说到日历组件,网上一搜一大堆,各种插件啊、集成框架啊实在不少。但是插件有的不合需求,框架嘛依赖关系一大堆,比如jQueryUI、bootstrap等。其实现在我就是想要一个轻量级的日历组件,功能也不需要很强大,只要能兼容所有浏览器,能选择任意年份日期和星期就可以了。
好了,废话不多说,直接上代码:
好了,先引入jQuery库。(发表一下感概:angularJS的数据双向绑定着实让我对jQuery的未来担忧了一阵子,不过jQuery毕竟存在的时间很久,API文档和应用方面实在太广泛了 * _ *,而且jQuery无可厚非是一款相当不错的DOM操作类库,至少我觉得段时间内这个地位无可动摇。所以大家还是大胆地用吧!)
