jQuery实现的简单日历组件定义与用法示例
Jafeney 人气:0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！）
<script type="text/javascript" src="./js/jQuery.min.js"></script>
下面这个是还没压缩的js文件，纯手写哦 ^_^

到了最关键的时刻，怎么使用呢？嘿嘿，就2行代码。
<!-- input group -->
<div class="input-group">
<input type="text" id="input-date" class="input-text">
</div>
<!--end input group-->
<script type="text/javascript">
;$(function(){
$('#input-date').dateField({
eventType:'click',
style:'default'
})
});
</script>
