JavaScript Date formatting method summary _javascript Tips

This article summarizes the JavaScript date formatting method. Share to everyone for your reference, specific as follows:

Adopt prototype:

Date.prototype.Format = function (FMT) {//author:meizz
  var o = {
    "m+": This.getmonth () + 1,//month
    "d+": this. GetDate (),//day
    "h+": this.gethours (),//hr
    "m+": this.getminutes (),//min "
    s+": This.getseconds (),
    //sec "q+": Math.floor (This.getmonth () + 3)/3),//Quarter
    "S": this.getmilliseconds ()//Millisecond
  };
  if (/(y+)/.test (FMT)) FMT = Fmt.replace (regexp.$1, (this.getfullyear () + ""). substr (4-regexp.$1.length));
  For (var k in O)
  if (new RegExp ("+ K +")). Test (FMT)) FMT = Fmt.replace (regexp.$1, (regexp.$1.length = 1)? (O[k]): (("+ o[k]"). substr (("" + o[k). length));
  return FMT;
}

Put this piece of code in <script></script>.

It is then invoked with the following statement:

Copy Code code as follows:

New Date (). Format ("Yyyy-mm-dd hh:mm:ss")

A brief summary of the date format (js date formatting) method in JavaScript is referred to in the previous article.

Another function to get the current date is as follows:

<script language= "JavaScript" >
<!--
var mydate = new Date ();
  Mydate.getyear ();    Gets the current year (2-bit)
  mydate.getfullyear ();  Get full year (4-bit, 1970-????)
  Mydate.getmonth ();   Get the current month (0-11, 0 for January)
  mydate.getdate ();    Gets the current day (1-31)
  mydate.getday ();    Get Current week x (0-6, 0 representative Sunday)
  Mydate.gettime ();    Gets the current time (the number of milliseconds since 1970.1.1)
  mydate.gethours ();   Gets the current number of hours (0-23)
  mydate.getminutes ();  Gets the current number of minutes (0-59)
  mydate.getseconds ();  Gets the current number of seconds (0-59)
  mydate.getmilliseconds ();  Gets the current number of milliseconds (0-999)
  mydate.tolocaledatestring ();  Gets the current date
  var mytime=mydate.tolocaletimestring ();  Gets the current time
  mydate.tolocalestring ();    Gets the date and time
if (mytime< "23:30:00")
{
alert (mytime);
}
-->
</SCRIPT>
