一个项目中，很多时候我们都需要选择时间的功能，一种能够将时间格式统一化的方法对于数据存储来说额为重要，然而使用一般文本框的形式或者下拉框的形式来完成这个功能的话就会比较繁琐，那么如何来用一个简单方法来实现这个功能呢，最理想的方式当然是使用日历控件了！
使用以下方法将会让你的程序减少不少麻烦，而且很美观哦！^ _ ^

首先，想使用日历，当然需要一个js日历控件了，新建一个Calendar.js文件（有了这个文件，以后想使用时调用以下就可以了，超方便），加入以下代码：

<!--
var cal;
var isFocus=false; //是否为焦点
//function SelectDate(obj,strFormat) //两个参数改为只传一个
function SelectDate(obj)
{
    var date = new Date();
    var by = date.getFullYear()-10; //最小值 → 10 年前
    var ey = date.getFullYear()+10; //最大值 → 10 年后
    cal = (cal==null) ? new Calendar(by, ey, 0) : cal;    //初始化为中文版，1为英文版
    //cal.dateFormatStyle = strFormat; // 默认显示格式为:yyyy-MM-dd ,还可显示 yyyy/MM/dd
    cal.show(obj);
}
/**//* 返回日期 */
String.prototype.toDate = function(style){
var y = this.substring(style.indexOf('y'),style.lastIndexOf('y')+1);//年
var m = this.substring(style.indexOf('M'),style.lastIndexOf('M')+1);//月
var d = this.substring(style.indexOf('d'),style.lastIndexOf('d')+1);//日
if(isNaN(y)) y = new Date().getFullYear();
if(isNaN(m)) m = new Date().getMonth();
if(isNaN(d)) d = new Date().getDate();
var dt ;
eval ("dt = new Date('"+ y+"', '"+(m-1)+"','"+ d +"')");
return dt;
}
/**//* 格式化日期 */
Date.prototype.format = function(style){
var o = {
    "M+" : this.getMonth() + 1, //month
    "d+" : this.getDate(),      //day
    "h+" : this.getHours(),     //hour
    "m+" : this.getMinutes(),   //minute
    "s+" : this.getSeconds(),   //second
    "w+" : "天一二三四五六".charAt(this.getDay()),   //week
    "q+" : Math.floor((this.getMonth() + 3) / 3), //quarter
    "S" : this.getMilliseconds() //millisecond
}
if(/(y+)/.test(style)){
    style = style.replace(RegExp.$1,
    (this.getFullYear() + "").substr(4 - RegExp.$1.length));
}
for(var k in o){
    if(new RegExp("("+ k +")").test(style)){
      style = style.replace(RegExp.$1,
        RegExp.$1.length == 1 ? o[k] :
        ("00" + o[k]).substr(("" + o[k]).length));
    }
}
return style;
};

//隐藏日历

//焦点转移时隐藏日历

}
document.write('<div id="ContainerPanel" style="display:none;"><div id="calendarPanel" style="position: absolute;display: none;z-index: 9999;');
document.write('background-color: #FFFFFF;border: 1px solid #CCCCCC;width:175px;font-size:12px;margin-left:25px;"></div>');
if(document.all)
{
document.write('<iframe style="position:absolute;z-index:2000;width:expression(this.previousSibling.offsetWidth);');
document.write('height:expression(this.previousSibling.offsetHeight);');
document.write('left:expression(this.previousSibling.offsetLeft);top:expression(this.previousSibling.offsetTop);');
document.write('display:expression(this.previousSibling.style.display);" scrolling="no" frameborder="no"></iframe>');
}
document.write('</div>');
//-->

然后，在你需要日历控件的页面中调用就可以了，例如我有一张页面aa.html，需要使用日历控件，只需要加入：

<script src="Calendar.js" type="text/javascript" language="javascript"></script>
<input name="txtDate" type="text" style="padding-left:5px;" size="10" id="txtDate" onclick="SelectDate(this)" readonly="readonly" />
