Date Object

Convert a Date object to a string

Converts a date and time in a Date object to a string

Milliseconds-related methods

One, Date object

There are no date-type data types in JavaScript, but a Date object is available to manipulate the date and time.

Creation of date objects:

New Date ();

Ii. Converting a Date object to a string

You can use the following 4 methods to convert a Date object to a string:

Date.tostring ();//When converting a Date object to a string, the local time is used

Date.tolocalstring ();//Converts a Date object to a string, using local time, showing the format of the local date

Date.toutcstring ();//When you convert a Date object to a string, the world time is used.

Date.togmtstring ();//The GMT time is used when converting a Date object to a string, but it is disabled and is generally replaced with the toUTCString () method.

Iii. converting dates and times in date objects to strings

Date.todatestring ();//Convert the date part to a string, local time

Date.tolocaldatestring ();//Converts the date part to a string, using the local time, which shows the format of the local date

Date.totimestring ();//Convert the time part to a string, local time

Date.tolocaltimestring (); Converts the time part to a string, using the local time, which shows the format of the local date

Iv. Dates in date objects

Date.getyear ();//Gets the year but is not recommended for use.

Date.getfullyear ();//Gets the year, in four-digit numbers, and recommends using

Date.getmonth ();//Gets the month, the value is 0-11, January is 0, February is 1 ...

Date.getdate ();//Gets the number of days, that is, one day in one months

Date.getday ();//Gets the day of the week, the value is 0-6, Sunday is 0 ...

V. Time in a Date object

Date.gethours ();//Return Hour section

Date.getminutes ();//Return minute part

Date.getseconds ();//Return second part

Date.getmilliseconds ();//returns the millisecond part

Date.gettime ();//Returns the number of milliseconds between the time in the Date object and the January 1, 1970 0:0 0 seconds

Date.gettimezoneoffset ();//Returns the number of times in seconds between the time in the Date object and UTC.

Vi. Setting the date in the Date object

Date.setyear (year);//Not recommended

Date.setfullyear (year,month,day);//year four digits; month:0-11, this parameter can be omitted; day:1-31, this parameter can be omitted

Date.setmonth (month,day);//month:0-11;day:1-31, this parameter can be omitted

Date.getdate (day);//day:1-31

Vii. setting the time in a Date object

Date.gethours (hours,minutes,seconds,milliseconds);//hours:0-23,minutes:0-59, can be omitted, seconds:0-59, can be omitted milliseconds:0 -999, can be omitted

Date.getminutes (minutes,seconds,milliseconds);//minutes:0-59,seconds:0-59, can omit milliseconds:0-999, can omit

Date.getseconds (seconds,milliseconds);//seconds:0-59,milliseconds:0-999, can be omitted

Date.getmilliseconds (milliseconds);//,milliseconds:0-999

Viii. methods related to milliseconds

Date.settime (millisecinds); milliseconds represents the number of milliseconds between the time that is set and the January 1, 1970 0:0 0 seconds

Date.valueof (); Returns the number of milliseconds between the time in the Date object and the January 1, 1970 0:0 0 seconds

Date.parse (str); Returns the number of milliseconds between the time that the str parameter represents and the January 1, 1970 0:0 0 seconds

Date. UTC (year,month,day,hours,minutes,seconds,milliseconds); Converts the date represented by the parameter to the number of milliseconds between January 1, 1970 0:0 and 0 seconds
