I've just read docs and haven't found any method that returns an array, so you need to do it only with loop
我刚刚阅读了文档，还没有找到任何返回数组的方法，所以你只需要使用循环来做
var monday = moment()
.startOf('month')
.day("Monday");
if (monday.date() > 7) monday.add(7,'d');
var month = monday.month();
while(month === monday.month()){
document.body.innerHTML += "<p>"+monday.toString()+"</p>";
monday.add(7,'d');
}

This function should work:
这个功能应该工作：
function getMondays(date) {
var d = date || new Date(),
month = d.getMonth(),
mondays = [];
d.setDate(1);
// Get the first Monday in the month
while (d.getDay() !== 1) {
d.setDate(d.getDate() + 1);
}
// Get all the other Mondays in the month
while (d.getMonth() === month) {
mondays.push(new Date(d.getTime()));
d.setDate(d.getDate() + 7);
}
return mondays;
}
Usage: getMondays()for this month, or getMondays(moment().month("Feb").toDate())for a different month.
用法：getMondays()本月或getMondays(moment().month("Feb").toDate())不同月。

You can get all the Mondays in the month by using my moment-weekdaysinmoment.js plugin:
您可以使用我的moment-weekdaysin moment.js 插件获取该月的所有星期一：
