javascript date and year

Question

I have the following javascript code:

<script type="text/javascript">
    $(function () {
        var currentDateTime = new Date();
        var oneYear = new Date();
        oneYear.setYear(oneYear.getYear() + 1);
        alert(currentDateTime + "_" + oneYear);
    });
</script>

i would expect the alert to output the current datetime and the datetime of one year from now. However I get this in the alert: "Fri Oct 22 2010 14:17:31 GMT-0400 (Eastern Daylight Time)_Thu Oct 22 0111 14:17:31 GMT-0400 (Eastern Daylight Time)"

Clearly it's not adding "1" to the Year correctly!

Whats going on? How did it become the year 0111???

It is correct. .getYear() returns "actual year − 1900". 2010 − 1900 = 110.

Use .getFullYear() instead. .getYear() has been deprecated for a long time.

Y2K was 10 years ago, but you're still using getYear instead of getFullYear? tsk tsk...

Instead of .getYear() try .getFullYear()
