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){}

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
也可以这样做:
var x = new Date().toString().split(' ')[1]; // "Jul"
文档。写(新日期()。toLocaleString('en-us',{月:'长',年:'数字',日:'数字'}))
另一种格式化日期的方法
new Date().toLocaleString('en-us',{month:'long', year:'numeric', day:'numeric'}) //output: "May 21, 2019"
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。
