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

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: [...]};
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){}
Angular的引用https://angular.io/api/common/DatePipe
我用了一个很有效的小窍门:
const monthNumber = 8; const yearNumber = 2018; const date = ' ${['Jan', 'Feb', 'Mar', 'Apr', “五月”,“六月”,“七月”,“八月”, 'Sep', 'Oct', 'Nov', 'Dec'][monthNumber - 1] } $ {yearNumber} '; console.log(日期);
对我来说,这是最佳解,
对于TypeScript也一样
const env = process.env.REACT_APP_LOCALE || 'en';
const namedMonthsArray = (index?: number): string[] | string => {
const months = [];
for (let month = 0; month <= 11; month++) {
months.push(
new Date(new Date('1970-01-01').setMonth(month))
.toLocaleString(env, {
month: 'long',
})
.toString(),
);
}
if (index) {
return months[index];
}
return months;
};
输出是
["January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"]
较短的版本:
const monthNames = ["January", "February", "March", "April", "May", "June", “七月”,“八月”,“九月”,“十月”,“十一月”,“十二月” ]; const d = new Date(); 文档。write("当前月份是" + monthNames[d.getMonth()]);
