--Returns the date and time of the day.
2, GetDate ()
--Returns one day of one months from the Date object (1 ~ 31).

In the article, the API is SimpleDateFormat, it belongs to Java.text.SimpleDateFormat, so please remember import come in!
Usage: SimpleDateFormat SDF = new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");
This line is the most important, it established the format of the conversion, YYYY is the full year, MM is the month, DD is the date, as for HH:mm:ss don't need me to explain it!
PS: Why some format uppercase, some format lowercase, it is afraid to avoid
Js obtains the summary of current date and time and other date operations.
The examples in this article share common scenarios of javascript time operations for your reference. The specific content is as follows:
Var myDate = new Date (); myDate. getYear (); // obtain the current year (2 digits) myDate. getFullYear (); // obtain the complete year (4 digits, 1970

Date ObjectThe Date object is used to process dates and times.To create the syntax for a Date object:var mydate=new Date ();Note: The Date object automatically saves the current date and time as its initial value.1.
When I used to solve this problem with ASP is quite simple, the ASP has the corresponding function DateDiff can give two days period interval How many months, how many days and how many seconds. When I searched through the PHP manual I found that PHP did not have a similar function.

It is convenient to use timestamp to record datetime, but sometimes it is not necessary to display the milliseconds after the decimal point, so you need to redefine the format when converting to string. timestamp converted to string: SimpleDateFormat df = new SimpleDateFormat ("Yyyy-mm-dd HH:mm:ss");//defines the format, does not display millisecondsTimestamp now = new Timestamp (System.currenttimemillis ());//Get system Current timeString str = Df.format (now); Convert String to timestamp: Simp

some interfaces for the external call, but in order to improve the JS library's robustness, needs to minimize the external interface (the most ideal is only saves the user needs the interface)! So here's a question, I'll instantiate it:
Copy Code code as follows:

Iofirst:function () {},
Iosecond:function () {}
}
Under the object namespace have a thing to Iofirst and Iosecond share, but do not want to expose this interface! I am through the inheritan
