Mydate.getmonth ();      //Get the current month (0-11, 0 for January)
Mydate.getdate ();        //Get current day (1-31)
Mydate.getday ();         //Get Current week x (0-6, 0 for Sunday)

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]: ("XX" + o[k]). substr (("" + o[k]). length);
}
}
return format;
}

How to use
var now = new Date ();
var nowstr = Now.format ("Yyyy-mm-dd hh:mm:ss");
Use Method 2:
var testdate = new Date ();
var teststr = Testdate.format ("yyyy mm month DD day hh hours mm min ss sec");
alert (TESTSTR);
Example:
Alert (new Date (). Format ("yyyy year mm DD Day"));
Alert (new Date (). Format ("mm/dd/yyyy"));
Alert (new Date (). Format ("YyyyMMdd"));
Alert (new Date (). Format ("Yyyy-mm-dd hh:mm:ss"));

JS format current time is YYYY-MM-DD form

function Getnowformatdate ()
{
var day = new Date ();
var year = 0;
var Month = 0;
var day = 0;
var currentdate = "";
Initialization time
Year= day.getyear ();//have Firefox next 2008 years show 108 bug
Year= day.getfullyear ();//ie Firefox can
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;
}
