js 日期格式化

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;

}

 

//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"));

 

js格式化当前时间为yyyy-mm-dd形式

复制代码 代码如下:

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;

}
