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");

不幸的是,提取月份名称的最佳方法是从UTCString表示中提取:
Date.prototype.monthName = function() {
return this.toUTCString().split(' ')[2]
};
d = new Date();
//=> Thu Mar 06 2014 23:05:21 GMT+0000 (GMT)
d.monthName();
//=> 'Mar'

如果您不介意扩展Date原型(并且有一些很好的理由不想这样做),您实际上可以提出一个非常简单的方法:
Date.prototype.monthNames = [
"January", "February", "March",
"April", "May", "June",
"July", "August", "September",
"October", "November", "December"
];
Date.prototype.getMonthName = function() {
return this.monthNames[this.getMonth()];
};
Date.prototype.getShortMonthName = function () {
return this.getMonthName().substr(0, 3);
};
// usage:
var d = new Date();
alert(d.getMonthName()); // "October"
alert(d.getShortMonthName()); // "Oct"
这些函数将应用于所有javascript Date对象。
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.
如果你赶时间……那就给你!
const date = new Date(Date.now());
date.toLocaleString('en-US', {month: 'short'}); // {month:'long'}
预期产出:“四月”
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));
最简单最简单的方法:
const dateStr =新的日期(2020,03,10).toDateString();//“2020年4月10日星期五” const dateStrArr = dateStr。分割(' ');// ['Fri', 'Apr', '10', '2020'] console.log (dateStrArr [1]);/ / 4月的
将日期转换为字符串。 间隔一个空格。 从数组中选择第二个元素。
