JS Get time new Date () detailed introduction __js

var mydate = new Date ();
Mydate.getyear (); Get Current year (2-bit)
Mydate.getfullyear (); Get full year (4-bit, 1970-????)
Mydate.getmonth (); Get Current month (0-11, 0 for January)//So get current month is mydate.getmonth () +1;
Mydate.getdate (); Get the current day (1-31)
Mydate.getday (); Get Current week x (0-6, 0 for Sunday)
Mydate.gettime (); Gets the current time (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

==========================================================================

JS Gets the current timestamp method-javascript The following three methods are available for obtaining the current millisecond timestamp:

var timestamp =date.parse (New Date ()); Results: 1280977330000//Not recommended; Milliseconds changed to 000 display

var timestamp = (new Date ()). valueof (); Results: 1280977330748//recommended;

var timestamp=new Date (). GetTime (); Results: 1280977330748//recommended;

JS to call the new Date () separately; Show this format 10:10:43 utc+0800 2012

But using the new Date () to participate in the calculation is automatically converted to the number of milliseconds starting from 1970.1.1

--------------------------------------------------------------------------------------------------

converts a date in the form of a string to a Date object

var strtime= "2011-04-16"; String date format
var date= new Date (Date.parse (Strtime.replace (/-/g, "/")); Convert to data ();

--------------------------------------------------------------------------------------------------

New Date (); parameter can be an integer; can also be a string; But the format must be correct

New Date (2009,1,1); That's right

New Date ("2009/1/1"); That's right

New Date ("2009-1-1"); Error

New Date (year, month, date, hrs, min, sec) Create a Date object by the given parameters
Parameter description:
Year's value is: the date that needs to be set-1900. For example, the year should be set at 1997, and the value should be 97, or 1997-1900. So date can be set to a minimum of 1900 years;
Month's range is 0~11,0 representative January, 11 table represents December;
The domain of date is between 1~31;
The range of hrs is between 0~23. From midnight to 1 o'clock in the morning hrs=0, between noon and 1 o'clock in the afternoon hrs=12;
The range between min and sec is between 0~59.
Example Date day=new date (11,3,4);
The time in day is: 04-apr-11 12:00:00 AM

In addition, you can also give incorrect parameters.
Example set time for February 30, 1910, it will be interpreted as March 2.
Date Day=new date (10,1,30,10,12,34);
System.out.println ("Day's date is:" +day);
The result is: Day ' s date is:web 10:13:34 gmt+08:00 1910------------------------------------------------------------- -------------------------------------

1. Current system locale format (tolocaledatestring and tolocaletimestring)

Example: (new Date ()). toLocaleDateString () + "" + (new Date ()). toLocaleTimeString ()
Results: January 29, 2008 16:13:11

2. Ordinary strings (todatestring and toTimeString)

Example: (new Date ()). toDateString () + "" + (new Date ()). toTimeString ()
Results: Tue 2008 16:13:11 utc+0800

3. Greenwich Standard Time (togmtstring)

Example: (New Date ()). toGMTString ()
Result: Tue, 2008 08:13:11 UTC

4. Global Standard Time (toutcstring)

Example: (New Date ()). toUTCString ()
Result: Tue, 2008 08:13:11 UTC

5.Date Object String (toString)

Example: (New Date ()). ToString ()
Result: Tue 16:13:11 utc+0800 2008

--------------------------------------------------------------------------------------------------

Date objects can also be used to compare two dates. var mydate=new Date ();      Mydate.setfullyear (2008,7,9);      var today = new Date ();       if (mydate>today) {...; }
