How do I use the Date object?

First, you need to get the Date object.

Get Wechat

Var d=new Date ()

When the date object is generated, the current time is returned by default without passing any parameters

Var d=new Date ('2015Uniqqq2')

In the case of passing in parameters, what is obtained is the passed time

Note: this parameter is a string.

Some methods:

1.d.getFullYear () gets the current year. | d.setFullYear (2012) returns the number of milliseconds from January 1, 1970 to the set time |

2.d.getMonth () gets the current month (Note: a small BUG, the current month starts at 0) | | d.setMonth (9) returns the number of milliseconds of the set month from January 1, 1970 to the current year.

3.d.getDate () gets the current date | | d.setDate () same as above

4. When getHours () is obtained

GetMinutes () get minutes

GetSeconds () get seconds

The time acquired by each machine varies because the method returns the local time; it is not international standard time

5. Modification of date

Date.parse ("2015-08-24"); get the number of milliseconds from 1970 to the set time

D.getTime (); gets the milliseconds from 1970 to the current time

D.setTime ()

New Date (time)

Create a date object and specify the number of milliseconds at a specified time

Or modify the time property, var d = new Date (); d.setTime (56521211021)
