JavaScript compatible with each browser's date conversion

var date = new Date (Date.parse ("2015-09-05". Replace (/-/g, "/")));
' 2015-09-05 ' is not available in each browser, using new Date (str) to correctly generate the Date object. The correct usage is ' 2015/09/06 '.

Date usage for javascript:

varMyDate =NewDate (); Mydate.getyear ();//get Current year (2-bit)Mydate.getfullyear ();//Get the full year (4-bit, 1970-????)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) why ask Hovertree.comMydate.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 ();//Get Current datevarMytime=mydate.tolocaletimestring ();//Get current TimeMydate.tolocalestring ();//get date and time

JS Gets the current timestamp method-javascript gets the current timestamp
JavaScript gets the current timestamp:
The first method:

var timestamp =date.parse (new Date ());

Results: 1280977330000

The second method:
var timestamp = (new Date ()). ValueOf ();
results: 1280977330748
The third method:
var timestamp=New Date (). GetTime ();
results: 1280977330748
the first: The time stamp obtained is the change of milliseconds to 000 display,
The second and third is to get the timestamp of the current millisecond.
my colleague and I in the process of using JS to display the analysis of the time remaining, the time is always changed to 0, the result is very strange, and finally found that the time of acquisition with Date.parse (Newdate ()) obtained by the time stamp to change the millisecond to 000 display, So the time difference calculation is inaccurate.
The time difference can be calculated using the second or third method. http://hovertree.com/menu/javascript/
JS, call the new date () Separately, for example document.write (new Date ());
displaying the result: Mar 10:10:43 utc+0800 2012 time in this format
but participating in the calculation with the new Date () is automatically converted to the number of milliseconds starting from 1970.1.1
