推荐答案

如此高效:

 const firstDayOfMonth = moment(`${ year }-${ month }`, 'YYYY-MM-DD');
 let weekIndices = [];

 let currentDay = moment(firstDayOfMonth, 'YYYY-MM-DD');
 weekIndices.push(currentDay.isoWeek());

 while(currentDay.month() === firstDayOfMonth.month()) {
     currentDay.add(1, 'weeks');
     weekIndices.push(currentDay.isoWeek());
 }

return weekIndices;
