function set _javascript technique for acquiring time in JavaScript

Below to introduce the next JS get Time function set.

$ (function () {
var mydate = new Date ();
var t=mydate.tolocalestring ();
$ ("#time"). Text (t);
$ ("#time"). Load ("untitled-1.html"); 
});

The time to get JavaScript is done using the built-in date function

var mydate = new Date ();
Mydate.getyear (); Gets the current year (2-bit)
mydate.getfullyear ();//Get Full year (4-bit, 1970-????)
Mydate.getmonth (); Get Current month (0-11, 0 for January)
mydate.getdate ()//Get current day (1-31)
mydate.getday ()//Get Current week x (0-6, 0 on behalf of Sunday)
Mydate.gettime (); Gets the current time (the number of milliseconds since 1970.1.1)
mydate.gethours ();//Get the current number of hours (0-23)
mydate.getminutes ()//Get the current number of minutes (0-59)
mydate.getseconds ()///Get the current number of seconds (0-59)
mydate.getmilliseconds ();//get Current number of milliseconds (0-999)
Mydate.tolocaledatestring (); Get current date
var mytime=mydate.tolocaletimestring ();//Get Current time
mydate.tolocalestring ();//Get Date and time
