Question

I’m looking for a js (or jQuery) function where I pass a start date and end date, and the function returns on inclusive list (array or object) of each date in that range.

For example, if I pass this function a date object for 2010-08-31 and for 2010-09-02, then the function should return:
2010-08-31
2010-09-01
2010-09-02

Anyone have a function that does that or know of a jQuery plugin that would include this functionality?

It sounds like you might want to use Datejs. It is extremely awesome.

If you use Datejs, here’s how you could do it:

function expandRange(start, end) // start and end are your two Date inputs
{
    var range;
    if (start.isBefore(end))
    {
        start = start.clone();
        range = [];

        while (!start.same().day(end))
        {
            range.push(start.clone());
            start.addDays(1);
        }
        range.push(end.clone());

        return range;
    }
    else
    {
        // arguments were passed in wrong order
        return expandRange(end, start);
    }
}

ex. for me:

expandRange(new Date('2010-08-31'), new Date('2010-09-02'));

returns an array with 3 Date objects:

[Tue Aug 31 2010 00:00:00 GMT-0400 (Eastern Daylight Time),
 Wed Sep 01 2010 00:00:00 GMT-0400 (Eastern Daylight Time),
 Thu Sep 02 2010 00:00:00 GMT-0400 (Eastern Daylight Time)]
