This should do what you asked.
这应该按照你的要求做。
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;
}

Try this
试试这个
<!DOCTYPE html>
<html>
<body>
<p id="demo">Click the button to display todays day of the week.</p>
<button onclick="myFunction()">Try it</button>
<script type="text/javascript">
function daysInMonth(month,year) {
return new Date(year, month, 0).getDate();
}
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()]);
}
console.log(b);}//b is the desired array
</script>
</body>
</html>

You can do the logic yourself pretty easily using the standard JavaScript Date object. Here's an example of getting one date to push into your array. Just loop through the entire month calling the method. (jsFiddle)
您可以使用标准的 JavaScript Date 对象很容易地自己完成逻辑。这是获取一个日期以推送到您的数组的示例。只需循环调用该方法即可。( jsFiddle)
var daysOfTheWeek = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
function getDisplay(month, day, year) {
var d = new Date(year, month-1, day);
return day + '. ' + daysOfTheWeek[d.getDay()];
}
array_push($dates, getDisplay(7, 4, 2012));

Try this and see the result in console.
试试这个并在控制台中查看结果。
<script>
var weekday = ['Sunday', 'Monday', 'Tuesday', 'Wednesday',
'Thursday', 'Friday', 'Saturday'];
var month = '7';
var year = '2012';
realMonth = parseInt(month,10)-1;
var monthObj = {};
for(var i=1;i<30;i++)
{
var d = new Date(year,realMonth,i);
monthObj[i] = weekday[d.getDay()];
}
console.log(monthObj);
</script>

I know this is an old question, but today a questionlinked to this, and I'd like to point out one don't really need to do much things other than convert day (0-6)to string (Sunday-Saturday)
我知道这是一个老问题，但今天有一个与此相关的问题，我想指出除了转换day (0-6)为string (Sunday-Saturday)
function getDays(year, month) { //month: 1-based, as normal person
--month //change it to 0-based, as Date object
let dayname = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday']
let date = new Date(year, month)
let result = []
while(date.getMonth()==month){
result.push(`${date.getDate()}. ${dayname[date.getDay()]}`)
date.setDate(date.getDate()+1)
}
return result;
}
console.log(getDays(2019,12))
