JavaScript: get an array of day names of a specified date (month / year)

How can I get the names of a given month / year all month long? eg:

var year = "2000";
var month = "7"

... some code here that makes an array with names of days of the given month...

and the output looks something like this:

Array ("1. Sunday", "2. Monday", "3. Tuesday", ... "29. Thursday", "30. Friday", "31. Saturday");

This should do what you requested.

function getDaysArray(year, month) {
    var numDaysInMonth, daysInWeek, daysIndex, index, i, l, daysArray;

    numDaysInMonth = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];
    daysInWeek = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
    daysIndex = { 'Sun': 0, 'Mon': 1, 'Tue': 2, 'Wed': 3, 'Thu': 4, 'Fri': 5, 'Sat': 6 };
    index = daysIndex[(new Date(year, month - 1, 1)).toString().split(' ')[0]];
    daysArray = [];

    for (i = 0, l = numDaysInMonth[month - 1]; i < l; i++) {
        daysArray.push((i + 1) + '. ' + daysInWeek[index++]);
        if (index == 7) index = 0;
    }

    return daysArray;
}

}

function myFunction()
{var b=[],weekday = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'],month=7,year=2000;
for(var i=1,l=daysInMonth(month,year);i<l;i++){
var d = new Date(year,month-1,i);
b.push(i+"."+weekday[d.getDay()]);
