var myDate = new Date();
重构日期格式化1：
Date.prototype.format = function(format) {
var o = {
"M+": this.getMonth() + 1, //month
"d+": this.getDate(), //day
"h+": this.getHours(), //hour
"m+": this.getMinutes(), //minute
"s+": this.getSeconds(), //second
"q+": Math.floor((this.getMonth() + 3) / 3), //quarter
"S": this.getMilliseconds() //millisecond
}
if (/(y+)/.test(format)) {
format = format.replace(RegExp.$1, (this.getFullYear() + "").substr(4 - RegExp.$1.length));
}
for (var k in o) {
if (new RegExp("(" + k + ")").test(format)) {
format = format.replace(RegExp.$1, RegExp.$1.length == 1 ? o[k] : ("00" + o[k]).substr(("" + o[k]).length));
}
}
return format;
}
重构日期格式化2(格式化当前时间为yyyy-mm-dd形式)：
function getNowFormatDate()
{
var day = new Date();
var Year = 0;
var Month = 0;
var Day = 0;
var CurrentDate = "";
//初始化时间
//Year= day.getYear();//有火狐下2008年显示108的bug
Year= day.getFullYear();//ie火狐下都可以
Month= day.getMonth()+1;
Day = day.getDate();
//Hour = day.getHours();
// Minute = day.getMinutes();
// Second = day.getSeconds();
CurrentDate += Year + "-";
if (Month >= 10 )
{
CurrentDate += Month + "-";
}
else
{
CurrentDate += "0" + Month + "-";
}
if (Day >= 10 )
{
CurrentDate += Day ;
}
else
{
CurrentDate += "0" + Day ;
}
return CurrentDate;
}
重构日期加减：
Date.prototype.DateAdd = function(strInterval, Number) {
var dtTmp = this;
switch (strInterval) {
case 's': return new Date(Date.parse(dtTmp) - (1000 * Number));
case 'n': return new Date(Date.parse(dtTmp) - (60000 * Number));
case 'h': return new Date(Date.parse(dtTmp) - (3600000 * Number));
case 'd': return new Date(Date.parse(dtTmp) - (86400000 * Number));
case 'w': return new Date(Date.parse(dtTmp) - ((86400000 * 7) * Number));
case 'q': return new Date(dtTmp.getFullYear(), (dtTmp.getMonth()) - Number * 3, dtTmp.getDate(), dtTmp.getHours(), dtTmp.getMinutes(), dtTmp.getSeconds());
case 'm': return new Date(dtTmp.getFullYear(), (dtTmp.getMonth()) - Number, dtTmp.getDate(), dtTmp.getHours(), dtTmp.getMinutes(), dtTmp.getSeconds());
case 'y': return new Date((dtTmp.getFullYear() - Number), dtTmp.getMonth(), dtTmp.getDate(), dtTmp.getHours(), dtTmp.getMinutes(), dtTmp.getSeconds());
}
}
alert(myDate.DateAdd('d', 7).format("yyyy-MM-dd hh:mm:ss"));
//使用方法
var now = new Date();
var nowStr = now.format("yyyy-MM-dd hh:mm:ss");
//使用方法2:
var testDate = new Date();
var testStr = testDate.format("YYYY年MM月dd日hh小时mm分ss秒");
alert(testStr);
//示例：
alert(new Date().Format("yyyy年MM月dd日"));
alert(new Date().Format("MM/dd/yyyy"));
alert(new Date().Format("yyyyMMdd"));
alert(new Date().Format("yyyy-MM-dd hh:mm:ss"));
