自己整理的一个javascript日期处理函数

复制代码 代码如下:

/*
* 函数名称: DateUtil
* 作 者: yithcn
* 功能说明: 日期函数
* 使用说明:
* 创建日期: 2010.10.14
*/
var DateUtil = {};
DateUtil.base = 60 * 60 * 24 * 1000;
DateUtil.Add = function(num, sDate) {
num = num || 0;
sDate = sDate || new Date();
var base = this.base * num;
var todayMs = sDate.getTime();
todayMs += base;
sDate.setTime(todayMs);
var m = (sDate.getMonth() + 1);
m = m < 10 ? "0" + m : m;
var d = sDate.getDate();
d = d < 10 ? "0" + d : d;
var y = sDate.getFullYear();
return m + "/" + d + "/" + y;
};
DateUtil.Diff = function(sDate, eDate, mode) {
if (typeof sDate == "string")
sDate = new Date(sDate);
if (typeof eDate == "string")
eDate = new Date(eDate);
sDate = sDate || new Date();

} catch (e) {

}

switch (mode) {
case "y":
result /= this.base * 365;
break;
case "m":
result /= this.base * 365 / 12;
break;
case "w":
result /= this.base * 7;
break;
default:
result /= this.base;
break;
}
return (Math.floor(result));
};
DateUtil.Time = function(hasSec) {
var date = new Date();
return date.getHours() + ":" + date.getMinutes() + (hasSec ? ":" + date.getSeconds() : "");
};
DateUtil.TimeSplit = function(hasSec) {
var date = new Date();
return { Hour: date.getHours(), Minute: date.getMinutes(), Second: (hasSec ? ":" + date.getSeconds() : "") };
};
