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");

我的最佳解决方案如下:
var dateValue = Date();
var month = dateValue.substring(4,7);
var date = dateValue.substring(8,10);
var year = dateValue.substring(20,24);
var finaldateString = date+"-"+month+"-"+year;

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: [...]};
现在可以使用ECMAScript国际化API来做到这一点:
const date = new date (2009,10,10);/ / 2009-11-10 Const month =日期。toLocaleString('default', {month: 'long'}); console.log(月);
“long”使用月份的全称,“short”使用简短的名称,“narrow”使用更简洁的版本,比如字母语言中的第一个字母。
你可以将浏览器的“默认”更改为任何你喜欢的语言环境(例如:'en-us'),它将为该语言/国家使用正确的名称。
使用toLocaleStringapi,你每次都必须传递locale和选项。如果你要在多个不同的日期使用相同的语言环境信息和格式选项,你可以使用Intl。DateTimeFormat相反:
const formatter = new Intl。DateTimeFormat('fr', {month: 'short'}); Const month1 =格式化程序。格式(新日期()); Const month2 = formatter。format(new Date(2003,5,12)); Console.log (' ${month1}和${month2} ');//当前月份的法语和“juin”。
有关更多信息,请参阅我关于国际化API的博客文章。
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.
如果您不想使用时刻,并希望显示月份名称-
.config($mdDateLocaleProvider) {
$mdDateLocaleProvider.formatDate = function(date) {
if(date !== null) {
if(date.getMonthName == undefined) {
date.getMonthName = function() {
var monthNames = [ "January", "February", "March", "April", "May", "June",
"July", "August", "September", "October", "November", "December" ];
return monthNames[this.getMonth()];
}
}
var day = date.getDate();
var monthIndex = date.getMonth();
var year = date.getFullYear();
return day + ' ' + date.getMonthName() + ' ' + year;
}
};
}
如果我们需要传递输入,那么我们需要使用以下方式
输入:“2020-12-28”
代码:
new Date('2020-12-28').toLocaleString('en-us',{month:'short', year:'numeric'})
输出:“2020年12月”
