why not just use the new Date() function in javascript?

new Date(year, month, day) months go from 0-11 using a day of 0 will result in the previous months last day.

//january 1st, 2012 
var d = new Date(2012, 0, 1);
alert(d)

//last day of january 2012 (month 1, day 0)
var d2 = new Date(2012, 1,0);
alert(d2);

Try this:

function daysInMonth(iMonth, iYear)
{
    return new Date(iYear, iMonth, 0).getDate();
}
