[转]一种简单的js时间控件

使用方法:

粘贴代码到文本文档中,文档名称为datetime.js,然后在html文件中引用如下代码即可

<input name="shijian1" id="shijian1" type="text" class="sang_Calender" />

<script type="text/javascript" src="js/datetime.js"></script><!-- 时间控件js文件(引用在标签之后) -->

注意type="text" class="sang_Calender"不可变,文件路径写即可使用

代码如下:

(function(){
var d=document,
w=window,
isIE=w.navigator.appVersion.indexOf("MSIE")>-1,

nowM=now.getMonth();
nowY=now.getFullYear();
