1.在工程文件下面新建文件夹"js",然后向其中添加JavaScript.js新建项，重命名为calendar.js。
2.向calendar.js中写入代码，
代码如下:
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()-80; //最小值 → 80 年前
var ey = date.getFullYear()+20; //最大值 → 20 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;
};
/**//*
