JavaScript Date setMilliseconds() Method
The date.setMilliseconds() method is used to set milliseconds into a date object which is created using the date() constructor.
Syntax:
dateObj.setMilliseconds(milliseconds_Value);
Parameter: This method accepts a single parameter as mentioned above and described below:
- milliseconds_Value: This parameter holds the value of millisecond which is used to set in the date() constructor.
Return Values:It returns the new i.e. updated millisecond which is set by the setMilliseconds() method.
Note: The DateObjis a valid Date object created using the Date() constructor in which we want to set the millisecond. The value of milliseconds is from 0 to 999.
Example 1: Below is the example of the Date setMilliseconds()method.
Javascript
// Here a date has been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996 05:35:32:77' ); // New millisecond of 52 is being set in above Date // Object with the help of setMilliseconds() method dateobj.setMilliseconds(52); // New millisecond from above Date Object is // being extracted using getMilliseconds() let B = dateobj.getMilliseconds(); // Printing new millisecond console.log(B); |
Output:
52
Example 2:If in the Date() constructor we do not give any millisecond, still setMilliseconds() method set a new millisecond which is given as its parameter.
Javascript
// Here millisecond has not been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996' ); // New millisecond of 51 is being set in above Date // Object with the help of setMilliseconds() method dateobj.setMilliseconds(51); // New millisecond from above Date Object is // being extracted using getMilliseconds() let B = dateobj.getMilliseconds(); // Printing new millisecond console.log(B); |
Output:
51
Program 3:If nothing as a parameter is given in the Date() constructor, still setMilliseconds() method set milliseconds but a month, year, date, etc become current ones. Here 42 is the new milliseconds, 4 is the current month i.e. April, 1 is the current date and 2018 is the current year.
Javascript
// Here nothing has been assigned // while creating Date object let dateobj = new Date(); // new millisecond of 42 is being set in // above Date Object with the help of // setMilliseconds() method dateobj.setMilliseconds(42); // Milliseconds from above Date Object is // being extracted using getMilliseconds() let B = dateobj.getMilliseconds(); // Month from above Date Object is // being extracted using getMonth() let C = dateobj.getMonth(); // Date from above Date Object is // being extracted using getDate() let D = dateobj.getDate(); // Year from above Date Object is // being extracted using getFullYear() let E = dateobj.getFullYear(); // Printing new milliseconds console.log(B); // Printing current month console.log(C); // Printing current date console.log(D); // Printing current year console.log(E); |
Output:
42 4 1 2018
Example 4:If the value of millisecond 1006 is given as the parameter of the setMilliseconds() method, It will set 6 as the millisecond because the millisecond range is from 0 to 999, and hence , here 1000 is subtracted because 0 to 999 is 1000.
Here 6 is the new millisecond and the second becomes 33 from 32 because the millisecond range is from 0 to 999 i.e, total 1000 and we set the new millisecond as 1006 which increases second by one to 33 from 32 and the millisecond becomes 6.
Javascript
// Here date has been assigned // while creating Date object let dateobj = new Date( 'October 13, 1996 05:35:32:45' ); // new millisecond of 1006 is being set // in above Date Object with the help of // setMilliseconds() method dateobj.setMilliseconds(1006); // milliseconds from above Date Object is // being extracted using getMilliseconds() let B = dateobj.getMilliseconds(); // Second from above Date Object is // being extracted using getSeconds() let C = dateobj.getSeconds(); // Printing new Milliseconds console.log(B); // Printing second console.log(C); |
Output:
6 33
