This should do what you asked.这应该按照您的要求进行。
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.您可以使用标准的 JavaScript Date 对象非常轻松地自己完成逻辑。 Here's an example of getting one date to push into your array.这是一个将一个日期推入数组的示例。 Just loop through the entire month calling the method.只需循环调用该方法的整个月。 ( jsFiddle ) （ 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 question linked 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，我想指出除了将day (0-6)转换为string (Sunday-Saturday)之外不需要做太多事情
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))
