我创建了一个有角材料日期选择器组件以与formly
一起使用,并尝试将其设置为对区域设置使用GB,以便日期显示为26/07/2019
。但是,输入日期时,它仍解析为美国,从而导致显示无效的日期错误。
我尝试加入moment
和MomentDateAdapter
模块,但无法解决问题。
这里是stackblitz
我将提供者设置为:
providers: [
{ provide: LOCALE_ID, useValue: 'en-GB' },
{ provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE] },
{ provide: MAT_DATE_FORMATS, useValue: MAT_MOMENT_DATE_FORMATS },
]
我的组件看起来像这样:
import { Component, ViewChild } from '@angular/core';
import { FormControl } from '@angular/forms';
import { FieldType } from '@ngx-formly/material';
import { MatInput } from '@angular/material';
import * as _moment from 'moment';
// tslint:disable-next-line:no-duplicate-imports
import {default as _rollupMoment} from 'moment';
const moment = _rollupMoment || _moment;
@Component({
selector: 'app-form-datepicker-type',
template: `
<input matInput
[errorStateMatcher]="errorStateMatcher"
[formControl]="formControl"
[matDatepicker]="picker"
[matDatepickerFilter]="to.datepickerOptions.filter"
[formlyAttributes]="field">
<ng-template #matSuffix>
<mat-datepicker-toggle [for]="picker"></mat-datepicker-toggle>
</ng-template>
<mat-datepicker #picker></mat-datepicker>
`,
})
export class DatepickerTypeComponent extends FieldType {
// Datepicker takes `Moment` objects instead of `Date` objects.
date = new FormControl(moment([2017, 0, 1]));
}

Sam,“键”使用两个提供程序“ MAT_DATE_FORMAT”和DateAdapter来解析/格式化值
{
"2019-7-25": {
"num_count": 5
},
"2019-7-26": {
"num_count": 5
}
}
如果用作DateAdapter MomentDateAdapter的提供,也要注入MAT_DATE_LOCALE
providers: [
{provide: DateAdapter, useClass: CustomDateAdapter},
{provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
],
但是您也可以使用CustomDateAdapter,它是一个具有两种功能的类,格式和解析
{provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]}

将LOCALE_ID更改为MAT_DATE_LOCALE
