Moment.js - 周一以isoWeekday()开始一周

Question

我正在创建一个日历,我以表格格式打印周.一个要求是,我可以根据某些用户选项在周一或周日开始这几周.我很难使用moment的isoWeekday方法.

// 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);
}

的jsfiddle

编辑我误解了isoWeekday实际在做什么.我认为它设置了"一周中的哪一天是一周的第一天"变量(不存在).它实际上只是改变星期几moment.weekday(),但是使用1-7范围而不是0-6.

Answer 1

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

Answer 2

startOf之前打电话isoWeekday.

var begin = moment(date).startOf('week').isoWeekday(1);

工作演示

Answer 3

这样，您可以设置一周的第一天。

moment.locale('en', {
    week: {
        dow: 6
    }
});
moment.locale('en');

确保使用它moment().weekday(1);而不是moment.isoWeekday（1）
