Calculating difference between two dates using JS

Hi,
I saw that someone asked a similar question before, but it's not what I'm looking for.
I have two date fields (check in, check out) and "number of days" field.
I want the script to calculate automatically the difference.
For example: I have defaults dates, and I want the script to put the difference in "number of days" field. And if the user will change the date, the number of days will change automatically.


Thanks,
Yotam

Have you tried this:

var numdays = Number(10);
var now = new Date();
var before = new Date();
before.setTime( now.getTime() - numdays * 24 * 60 * 60 * 1000);
