利用JS实现Web日历控件（包括日期和时间）
1.由于项目需要，需要一个精确到分钟的日历控件，具体如下图所示。
2.具体包括WebCalendar.js和一个schedule.jsp两个文件，源码如下。
（1）WebCalendar.js
var cal;
var isFocus=false; //是否为焦点
var pickMode ={
"second":1,
"minute":2,
"hour":3,
"day":4,
"month":5,
"year":6 };
var topY=0,leftX=0; //自定义定位偏移量
//选择日期，通过 ID 来选日期
function SelectDateById(id,strFormat,x,y)
{
var obj = document.getElementById(id);
if(obj == null){return false;}
obj.focus();
if(obj.onclick != null){obj.onclick();}
else if(obj.click != null){obj.click();}
else{SelectDate(obj,strFormat,x,y)}
}
//选择日期
function SelectDate(obj,strFormat,x,y)
{
leftX =(x == null) ? leftX : x;
topY =(y == null) ? topY : y;//自定义定位偏移量
if(document.getElementById("ContainerPanel")==null){InitContainerPanel();}
var date = new Date();
var by = date.getFullYear()-50; //最小值 → 50 年前
var ey = date.getFullYear()+50; //最大值 → 50 年后
//cal = new Calendar(by, ey,1,strFormat); //初始化英文版，0 为中文版
cal = (cal==null) ? new Calendar(by, ey, 0) : cal; //不用每次都初始化 2006-12-03 修正
cal.DateMode =pickMode["second"]; //复位
if(strFormat.indexOf('s')< 0) {cal.DateMode =pickMode["minute"];}//精度为分
if(strFormat.indexOf('m')< 0) {cal.DateMode =pickMode["hour"];}//精度为时
if(strFormat.indexOf('h')< 0) {cal.DateMode =pickMode["day"];}//精度为日
if(strFormat.indexOf('d')< 0) {cal.DateMode =pickMode["month"];}//精度为月
if(strFormat.indexOf('M')< 0) {cal.DateMode =pickMode["year"];}//精度为年
if(strFormat.indexOf('y')< 0) {cal.DateMode =pickMode["second"];}//默认精度为秒
cal.dateFormatStyleOld = cal.dateFormatStyle;
cal.dateFormatStyle = strFormat;
cal.show(obj);
}
