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.
date对象中一些常见的简单处理可以通过它来完成。
var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; var monthShortNames = ["Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec" ]; function dateFormat1(d) { var t = new Date(d); return t.getDate() + ' ' + monthNames[t.getMonth()] + ', ' + t.getFullYear(); } function dateFormat2(d) { var t = new Date(d); return t.getDate() + ' ' + monthShortNames[t.getMonth()] + ', ' + t.getFullYear(); } console.log(dateFormat1(new Date())) console.log(dateFormat2(new Date()))
或者你可以制作日期原型
Date.prototype.getMonthName = function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; return monthNames[this.getMonth()]; } Date.prototype.getFormatDate = function() { var monthNames = ["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December" ]; return this.getDate() + ' ' + monthNames[this.getMonth()] + ', ' + this.getFullYear(); } console.log(new Date().getMonthName()) console.log(new Date().getFormatDate())
Ex:
var dateentt3新日期()#发情
var dateFormat4 = new Date().getFormatDate();# 16 三月, 2017
如果你正在使用jQuery,你可能也在使用jQuery UI,这意味着你可以使用$.datepicker. formatdate()。
$.datepicker.setDefaults( $.datepicker.regional[ "nl" ] ); // dutch
$.datepicker.formatDate( "dd MM yy", objDate );
如果你赶时间……那就给你!
const date = new Date(Date.now());
date.toLocaleString('en-US', {month: 'short'}); // {month:'long'}
