Javascript 在angular 2和Ionic 2中,将公历日期转换为波斯语(jalali)日期
我很熟悉npm中的一个将格里高利日期转换为波斯语(jalali)的包,但我不知道如何在ionic 2和ionic 2项目中使用它 或此软件包适用于angular 1:Javascript 在angular 2和Ionic 2中,将公历日期转换为波斯语(jalali)日期,javascript,ionic-framework,angular,ionic2,Javascript,Ionic Framework,Angular,Ionic2,我很熟悉npm中的一个将格里高利日期转换为波斯语(jalali)的包,但我不知道如何在ionic 2和ionic 2项目中使用它 或此软件包适用于angular 1: 是否可以将此软件包转换为angular 2?有什么想法吗?或者欢迎使用教程…好的,我为此编写了convertor 首先在项目中添加提供程序: import {Injectable} from '@angular/core'; @Injectable() export class PersianCalendarService {

下一步:在@Page部分实现提供者的名称
@Page({
templateUrl: 'build/pages/getting-started/getting-started.html',
providers: [PersianCalendarService]
})
在构造函数中
constructor(
public persianCalendarService: PersianCalendarService) {}
然后只需将日期传递给函数,即可获得Jalali date的良好输出:
getJalaliDate(date) {
var date1 = this.persianCalendarService.PersianCalendar(date);
this.farsiDate = date1;
}
我将很快在github中添加此代码。
谢谢将模块用作以下代码
import * as moment from 'jalali-moment';
let jalaliDate = moment('1989/1/24').locale('fa').format('YYYY/M/D'); // 1367/11/4
您可以通过Jalali日历和公历之间的毫秒差来实现这一点,以下是我的解决方案:
var g_date = new Date("2018-04-04 00:00:00"); // example Gregorian date
g_date_in_milliseconds = date.getTime(); // Gregorian date in milliseconds
const difference = 1.9603638 * Math.pow(10, 13); // difference of Jalali calendar and Gregoria
j_date_in_milliseconds = g_date_in_milliseconds - difference; // converted to Jalali milliseconds
j_date = new Date(j_date_in_milliseconds); // converted to date object
你可以很容易地用这种方法把贾拉利转换成格里高利:
g_date_in_milliseconds = j_date_in_milliseconds + difference;
g_date = new Date(g_date_in_milliseconds);
简单地说:
new Date(2019,2,21).toLocaleDateString('fa-Ir');
//输出=>۱۳۹۸/۱/۱
没有必要使用任何软件包。你可以使用这个方法 它的使用非常简单:
var d=新日期();
控制台信息(d.toLocaleDateString(“fa-IR”))
输出类似于۱۳۹/۳/۱۰
但是你可以使用选项让它看起来更好!例如:
const options={year:'numeric',month:'long',day:'numeric'};
控制台信息(d.toLocaleDateString(“fa-IR”,选项))
//输出>输出>输出>输出
注意:如果您将方向更改为rtl
它看起来很正常
再举一个例子:
const options={weekday:'long',year:'numeric',month:'long',day:'numeric'};
控制台信息(d.toLocaleDateString(“fa-IR”,选项))
//输出>输出>输出>输出>输出>输出>输出
再次:您必须使用rtl
方向以正确的方式查看它
您还可以使用来显示时间。像这样:
console.info(d.toLocaleDateString(“fa-IR”);
//输出>۱۶:۰:۰
const options={weekday:'long',year:'numeric',month:'long',day:'numeric'};
console.info(d.toLocaleDateString(“fa-IR”,选项));
//输出>输出>输出>输出>输出>输出>输出 ۱۶:۰۴:۱۶
这是最后一次!不要忘记方向。rtl
就我而言,它不起作用。因此,我将上面的代码示例更改为“let jalaliDate=moment(新日期('1989/1/24'))。locale('fa')。format('YYYY/M/D');//1367/11/4'我在网上找到了这个答案,大约8个月了,现在又找到了,谢谢程序员先生(亲爱的阿米尔同胞)。这里有一个日期选择器,请随意查看。Tnx阿米尔,你在电报或社交媒体上有社区吗?这是我的电子邮件:rezvani。frontDev@gmail.com和GitHub:GitHub.com/Abolfazl2647/
new Date(2019,2,21).toLocaleDateString('fa-Ir');
