Below is the example of Date setFullYear() method.
- Example:
<script>
// Here a date has been assigned
// while creating Date object
var
dateobj =
new
Date(
'October 13, 1996 05:35:32'
);
// New year 1992 is being set in above Date
// Object with the help of setFullYear() method
dateobj.setFullYear(1992);
// New year from above Date Object is
// being extracted using getFullYear()
var
B = dateobj.getFullYear();
// Printing new year
document.write(B);
</script>
- Output:
1992
The date.setFullYear() method is used to set year into a date object which is created using Date() constructor.
Syntax:
DateObj.setFullYear(year_Value)
Parameter: This method accept a single parameter as mentioned above and described below:
- year_Value: This parameter holds the value of year which is used to set in Date() constructor.
Return Value: It returns the new date with updated year which is set by setFullYear() method.
Note: The DateObj is a valid Date object created using Date() constructor in which we want to set the year.
More codes for the above method are as follows:
Program 1: If in Date() constructor we do not give any year, still setFullYear() method set new year which is given as its parameter.
<script> // Here year has not been assigned // while creating Date object var dateobj = new Date( 'October 13, 05:35:32' ); // new year 1992 is being set in above Date // Object with the help of setFullYear() method dateobj.setFullYear(1992); // New year from above Date Object is // being extracted using getFullYear() var B = dateobj.getFullYear(); // Printing new year document.write(B); </script> |
Output:
1992
Program 2: If nothing as parameter is given in Date() constructor, still setFullYear() method set year but month and date become current ones. Here in output 2 is the month of March because month name start from 0 to 11 i.e, 0 for January and 11 for December and 30 is the current date.
<script> // Here nothing has been assigned // while creating Date object var dateobj = new Date(); // new year 2007 is being set in above Date // Object with the help of setFullYear() method dateobj.setFullYear(2007); // Year from above Date Object is // being extracted using getFullYear() var B = dateobj.getFullYear(); // Month from above Date Object is // being extracted using getMonth() var C = dateobj.getMonth(); // Date from above Date Object is // being extracted using getDate() var D = dateobj.getDate(); // Printing new year document.write(B + "<" <br /> ">" ); // Printing current month document.write(C + "<" <br /> ">" ); // Printing current date document.write(D); </script> |
Output:
2007 2 30
