这是我使用棱角材质的日期选择器时得到的日期格式。...Wed Nov 21 2018 00:00:00 GMT+0530 (India Standard Time)
但是我需要(YYYY-MM-DD)
或(YYYY-MM-DDTHH:mm)
这种格式的日期。
这是我用来从角形材料形式捕获数据的模型类
export class FlightSchedule {
constructor(
public destination: string,
public origin: string,
public date: string,
public limit: string
) {}
}
请帮助我,我无法将日期转换为YYYY-MM-DD
或YYYY-MM-DDTHH:mm
格式。
我是Angular的新手
预先感谢

无需使用MomentDateAdapter
!
这是我使用MAT_NATIVE_DATE_FORMATS
使用最少代码和的解决方案。
import { MatDateFormats, MAT_NATIVE_DATE_FORMATS } from '@angular/material';
export const GRI_DATE_FORMATS: MatDateFormats = {
...MAT_NATIVE_DATE_FORMATS,
display: {
...MAT_NATIVE_DATE_FORMATS.display,
dateInput: {
year: 'numeric',
month: 'short',
day: 'numeric',
} as Intl.DateTimeFormatOptions,
}
};
@Component({
selector: 'app-vacation-wizard',
templateUrl: './vacation-wizard.component.html',
styleUrls: ['./vacation-wizard.component.scss'],
providers: [
{ provide: MAT_DATE_FORMATS, useValue: GRI_DATE_FORMATS },
]
})
别忘了设置适当的语言!
constructor(private readonly adapter: DateAdapter<Date>) {}
this.adapter.setLocale(this.translate.currentLang);
仅此而已!

您需要提供一个包含您要使用的格式的对象。该对象应类似于:
export const MY_FORMATS = {
parse: {
dateInput: 'LL',
},
display: {
dateInput: 'YYYY-MM-DD',
monthYearLabel: 'YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'YYYY',
},
};
然后,您需要将其添加到您的provider数组中,如下所示:
import { MAT_DATE_FORMATS } from '@angular/material';
import { MomentDateAdapter } from '@angular/material-moment-adapter';
//...
providers: [
{provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},
{provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
],

mask = df['B'].eq(6)
#alternative
#mask = (df['B'] == 6)
df['No_of_6'] = mask.astype(int).groupby(df['Id']).transform('sum')
在您的app.module中添加以上代码。它对我来说很完美。

modelChanged(date) {
var theDate = new Date(Date.parse(date));
const localDate = theDate.toLocaleString().split(" ");
console.log(localDate);
}
