var d = new Date();
console.log(d);
d.setMonth(d.getMonth() + 1); // set month as next month
console.log(d);
d.setDate(0); // get the last day of previous month
console.log(d);

以下是上述代码的输出:
2013年10月3日星期四11:34:59 GMT + 0100(GMT日光时间)

有时你只拥有本月的文字版本,即:2017年4月。
//first and last of the current month
var current_month = "April 2017";
var arrMonth = current_month.split(" ");
var first_day = new Date(arrMonth[0] + " 1 " + arrMonth[1]);
//even though I already have the values, I'm using date functions to get year and month
//because month is zero-based
var last_day = new Date(first_day.getFullYear(), first_day.getMonth() + 1, 0, 23, 59, 59);
//use moment,js to format
var start = moment(first_day).format("YYYY-MM-DD");
var end = moment(last_day).format("YYYY-MM-DD");

Date lastDayOfMonth = cal.getTime();

别忘了月份从0开始,所以月份也为+1。
let enddayofmonth = new Date(year, month, 0).getDate();
