由Javascript实现的页面日历


效果图:

CSS代码:

复制代码 代码如下:

<style type="text/css">
*{
margin:0;
padding:0;
font:10px tahoma;
}
#calender{
text-align:center;
width:147px;
font-size:10px;
/*color: #27B0C1;*/
margin:12px 0 12px 6px;
border-top:1px solid #EEEEEE;
border-left:1px solid #EEEEEE;
}
#calender .arrow_over{
color: #FF1493;
}
#calender .arrow_out{
color: #FF8C00;
}
#calender td{
border-bottom:1px solid #EEEEEE;
border-right:1px solid #EEEEEE;
width:21px;
height:20px;
line-height:16px;
color:#666666;
}
#calender #cal_title{
width:147px; background:#EFEFEF;
}
#calender #week td{
background: #F8F8F8;
}
#calender .current{
background: #AAE7E8;
display: block;
margin:2px;
}
#calender .notcurrent{
display: block;
margin:2px;
background:#EDEDED;
}
</style>

脚本代码:
复制代码 代码如下:

<script type="text/javascript">
