weekdays

// 从 2.12.0 版本开始
moment.updateLocale('en', {
    weekdays : String[]
});
moment.updateLocale('en', {
    weekdays : Function
});
moment.updateLocale('en', {
    weekdays : {
        standalone : String[],
        format : String[],
        isFormat : RegExp
    }
});
// 从 2.11.0 版本开始
moment.locale('en', {
    weekdays : {
        standalone : String[],
        format : String[],
        isFormat : Boolean
    }
});
// 从 2.8.1 至 2.11.2 版本
moment.locale('en', {
    weekdays : String[]
});
moment.locale('en', {
    weekdays : Function
});

// 废弃于 2.8.1 版本
moment.lang('en', {
    weekdays : String[]
});
moment.lang('en', {
    weekdays : Function
});

Locale#weekdays 应是工作日名称的数组。

moment.updateLocale('en', {
    weekdays : [
        "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"
    ]
});

Locale#weekdays 也可以是回调函数。

moment.updateLocale('en', {
    weekdays : function (momentToFormat, format) {
        return weekdays[momentToFormat.day()];
    }
});

注意：从 2.11.0 版本开始，format/standalone 用例也可以传入。 isFormat 将会用于完整的格式字符串，以判断要使用的格式。

moment.updateLocale('en', {
    weekdays : {
        standalone: 'Воскресенье_Понедельник_Вторник_Среда_Четверг_Пятница_Суббота'.split('_'),
        format: 'Воскресенье_Понедельник_Вторник_Среду_Четверг_Пятницу_Субботу'.split('_'),
        isFormat: /\[ ?[Вв] ?(?:прошлую|следующую|эту)? ?\] ?dddd/
    }
});

// From version 2.12.0 onward
moment.updateLocale('en', {
    weekdays : String[]
});
moment.updateLocale('en', {
    weekdays : Function
});
moment.updateLocale('en', {
    weekdays : {
        standalone : String[],
        format : String[],
        isFormat : RegExp
    }
});
// From version 2.11.0
moment.locale('en', {
    weekdays : {
        standalone : String[],
        format : String[],
        isFormat : Boolean
    }
});
// From version 2.8.1 to 2.11.2
moment.locale('en', {
    weekdays : String[]
});
moment.locale('en', {
    weekdays : Function
});

// Deprecated version 2.8.1
moment.lang('en', {
    weekdays : String[]
});
moment.lang('en', {
    weekdays : Function
});

Locale#weekdays should be an array of the weekdays names.

moment.updateLocale('en', {
    weekdays : [
        "Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"
    ]
});

Locale#weekdays can be a callback function as well.

moment.updateLocale('en', {
    weekdays : function (momentToFormat, format) {
        return weekdays[momentToFormat.day()];
    }
});

Note: From version 2.11.0 format/standalone cases can be passed as well. isFormat will be used against the full format string to determine which form to use.

moment.updateLocale('en', {
    weekdays : {
        standalone: 'Воскресенье_Понедельник_Вторник_Среда_Четверг_Пятница_Суббота'.split('_'),
        format: 'Воскресенье_Понедельник_Вторник_Среду_Четверг_Пятницу_Субботу'.split('_'),
        isFormat: /\[ ?[Вв] ?(?:прошлую|следующую|эту)? ?\] ?dddd/
    }
});
