JS：怎么得到给定月份的开始和结束时间

Answer 1

下面是一个提供所需输出的示例函数：
function getMonthDateRange(year, month) {
var moment = require('moment');

// month in moment is 0 based, so 9 is actually october, subtract 1 to compensate
// array is 'year', 'month', 'day', etc
var startDate = moment([year, month - 1]);

// Clone the value before .endOf()
var endDate = moment(startDate).endOf('month');

// just for demonstration:
console.log(startDate.toDate());
console.log(endDate.toDate());

// make sure to call toDate() for plain JavaScript date type
return { start: startDate, end: endDate };}
