Parameter: This function does not takes any parameter. It is just used along with a Date Object from which we want to fetch milliseconds.

Return values: It returns the millisecond for the given date object. Milliseconds is an integer value ranging from 0 to 999.

  code

  <script>   // Here a date has been assigned   // while creating Date object   var DateObj = new Date('October 15, 1996 05:35:32:77');      // millisecond from above date object is   // being extracted using getMilliseconds().   var millisec = DateObj.getMilliseconds();      // Printing millisecond   document.write(millisec); </script>

  filter_none

  Output:

  77

Errors and Exceptions:

• Example 1: The date of the month should must lie in between 1 to 31 because none of the month have date greater than 31 that is why it returns NaN i.e, not a number because date for the month does not exist.

  <script>   // Creating a Date Object   var DateObj = new Date();      // millisecond from above Date object is being   // extracted using getMilliSeconds()   var millisec = DateObj.getMilliseconds();      // Printing current millisecond   document.write(millisec); </script>

  filter_none

  Output:

  279

• Example 4: If millisecond as 1003 is given while creating the Date object, the function will return 0 as exception because milliseconds range is in between 0 to 999 and 1003 is out of this range.
