如何在JavaScript中从这个日期对象生成月份的名称(例如:10月/ 10月)?

var objDate = new Date("10/11/2009");

当前回答

只需要编写一个简单的toLocaleString包装器:

函数 LocalDate(locale) { this.locale = locale; } LocalDate.prototype.getMonthName = function(date) { return date.toLocaleString(this.locale,{month:“long”}); }; var objDate = new Date(“10/11/2009”); var localDate = new LocalDate(“en”); console.log(localDate.getMonthName(objDate)); localdate.locale = “ru”; console.log(localDate.getMonthName(objDate)); localdate.locale = “zh”; console.log(localDate.getMonthName(objDate));

其他回答

这是另一个,支持本地化:)

Date.prototype.getMonthName = function(lang) {
    lang = lang && (lang in Date.locale) ? lang : 'en';
    return Date.locale[lang].month_names[this.getMonth()];
};

Date.prototype.getMonthNameShort = function(lang) {
    lang = lang && (lang in Date.locale) ? lang : 'en';
    return Date.locale[lang].month_names_short[this.getMonth()];
};

Date.locale = {
    en: {
       month_names: ['January', 'February', 'March', 'April', 'May', 'June', 'July', 'August', 'September', 'October', 'November', 'December'],
       month_names_short: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec']
    }
};

然后,您可以轻松地添加对其他语言的支持:

Date.locale.fr = {month_names: [...]};

较短的版本:

const monthNames = ["January", "February", "March", "April", "May", "June", “七月”,“八月”,“九月”,“十月”,“十一月”,“十二月” ]; const d = new Date(); 文档。write("当前月份是" + monthNames[d.getMonth()]);

注(2019-03-08)-我最初在2009年写的这个答案已经过时了。请参阅David Storey的回答以获得更好的解决方案。

我衷心推荐moment.js库中的format函数,你可以这样使用它:

moment().format("MMM");  // "Apr" - current date
moment(new Date(2012, 01, 04)).format("MMM");  // "Feb" - from a local date
moment.utc(new Date(2012, 00, 04).format("MMM"); // "Jan" - from a UTC date

如果你需要当月的全称,可以用“MMMM”而不是“MMM”

除了一长串其他特性之外,它还具有强大的国际化支持。

如果你使用剑道,也可以这样做。

kendo.toString(dateobject, "MMMM");

以下是kendo网站上的格式化器列表:

"d" Renders the day of the month, from 1 through 31. "dd" The day of the month, from 01 through 31. "ddd" The abbreviated name of the day of the week. "dddd" The full name of the day of the week. "f" The tenths of a second in a date and time value. "ff" The hundredths of a second in a date and time value. "fff" The milliseconds in a date and time value. "M" The month, from 1 through 12. "MM" The month, from 01 through 12. "MMM" The abbreviated name of the month. "MMMM" The full name of the month. "h" The hour, using a 12-hour clock from 1 to 12. "hh" The hour, using a 12-hour clock from 01 to 12. "H" The hour, using a 24-hour clock from 1 to 23. "HH" The hour, using a 24-hour clock from 01 to 23. "m" The minute, from 0 through 59. "mm" The minute, from 00 through 59. "s" The second, from 0 through 59. "ss" The second, from 00 through 59. "tt" The AM/PM designator. "yy" The last two characters from the year value. "yyyy" The year full value. "zzz" The local timezone when using formats to parse UTC date strings.

我是通过DatePipe完成的。

const datePipe = new DatePipe(this.locale);
datePipe.transform(myDate, 'MMM. y');

你可以像这样在构造函数中注入默认区域:

constructor(@Inject(LOCALE_ID) private locale: string){}
