使用isoWeekday()从星期一开始 [英] Starting the week on Monday with isoWeekday()

问题描述

我正在创建一个日历，并以表格格式打印出数周.一个要求是，根据某些用户的选择，我可以在星期一或星期日开始几周.我很难使用矩型的 isoWeekday 方法.

I'm creating a calendar where I print out weeks in a tabular format. One requirement is that I be able to start the weeks either on Monday or Sunday, as per some user option. I'm having a hard time using moment's isoWeekday method.

// Start of some date range. Can be any day of the week.
var startOfPeriod = moment("2013-06-23T00:00:00"),

    // We begin on the start of the first week.
    // Mon Tues Wed Thur Fri Sat Sun
    // 20  21   22  23   24  25  26
    begin = moment(startOfPeriod).isoWeekday(1); // will pull from user setting

console.log(begin.isoWeekday()); // 1 - all good

// Let's get the beginning of this first week, respecting the isoWeekday
begin.startOf('week');

console.log(begin.isoWeekday()); // 7 - what happened ???

// Get column headers
for (var i=0; i<7; i++) {
    console.log(begin.format('ddd')); // I want Monday first!
    begin.add('d', 1);
}

编辑我误解了isoWeekday的实际操作.我以为它设置了一周中的哪一天是一周中的第一天"变量(不存在).实际上，它实际上只是更改星期几，就像moment.weekday()一样，但是使用1-7范围而不是0-6.

EDIT I misunderstood what isoWeekday was actually doing. I thought it set the "which day of the week is the first day of the week" variable (that doesn't exist). What it actually does is simply changes the day of the week, just like moment.weekday(), but uses a 1-7 range instead of the 0-6.

推荐答案

尝试使用begin.startOf('isoWeek');而不是begin.startOf('week');
