Date.prototype.getMonthName = function() {
    var monthNames = [ "January", "February", "March", "April", "May", "June", 
                       "July", "August", "September", "October", "November", "December" ];
    return monthNames[this.getMonth()];
}

它可以被用作

var month_Name = new Date().getMonthName();

如果你不想使用一个外部库，或者存储一个月份名称的数组，或者如果ECMAScript国际化API因为浏览器兼容性而不够好，你可以通过从日期输出中提取信息来实现:

var now = new Date();
var monthAbbrvName = now.toDateString().substring(4, 7);

这将为您提供缩写的月份名称，例如october。我相信日期将以各种格式出现，这取决于初始化和您的地区，因此请查看toDateString()返回的内容，并基于此重新计算您的substring()值。

获取月份名称的数组:

Date.monthNames = function( ) {
var arrMonth = [],
    dateRef = new Date(),
    year = dateRef.getFullYear();

dateRef.setMonth(0);
while (year == dateRef.getFullYear()) {
    /* push le mois en lettre et passe au mois suivant */
    arrMonth.push( (dateRef.toLocaleString().split(' '))[2] );
    dateRef.setMonth( dateRef.getMonth() + 1);
}

return arrMonth;
}

alert(Date.monthNames().toString());

// -> janvier,février,mars,avril,mai,juin,juillet,août,septembre,octobre,novembre,décembre

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

将名称存储在一个数组中，并根据月份的索引进行查找。

var month=new Array(12);
month[0]="January";
month[1]="February";
month[2]="March";
month[3]="April";
month[4]="May";
month[5]="June";
month[6]="July";
month[7]="August";
month[8]="September";
month[9]="October";
month[10]="November";
month[11]="December";

document.write("The current month is " + month[d.getMonth()]);

JavaScript getMonth()方法

如果你赶时间……那就给你!

const date = new Date(Date.now());
date.toLocaleString('en-US', {month: 'short'}); // {month:'long'}
