javascript 时间 utc 格式转化函数

方法一：

function Todate(num)

{ //Fri Oct 31 18:00:00 UTC+0800 2008

num=num+"";

var date="";

var month=new Array();

month["Jan"]=1;month["Feb"]=2;month["Mar"]=3;month["Apr"]=4;month["May"]=5;month["Jan"]=6;

month["Jul"]=7;month["Aug"]=8;month["Sep"]=9;month["Oct"]=10;month["Nov"]=11;month["Dec"]=12;

var week=new Array();

week["Mon"]="一";week["Tue"]="二";week["Wed"]="三";week["Thu"]="四";week["Fri"]="五";week["Sat"]="六";week["Sun"]="日";

str=num.split(" ");

date=str[5]+"-";

date=date+month[str[1]]+"-"+str[2]+"-"+str[3];

//date=date+" 周"+week[str[0]];

return date;

}

方法二：

Date.prototype.format = function(format) // author : meizz

{

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;

}

Date d = new Date();

document.write(d.format("yyyy-MM-dd"));
