打字稿:
import {Component} from '@angular/core';
import {FormControl} from '@angular/forms';
import {MomentDateAdapter, MAT_MOMENT_DATE_ADAPTER_OPTIONS} from '@angular/material-moment-adapter';
import {DateAdapter, MAT_DATE_FORMATS, MAT_DATE_LOCALE} from '@angular/material/core';
import {MatDatepicker} from '@angular/material/datepicker';
// Depending on whether rollup is used, moment needs to be imported differently.
// Since Moment.js doesn't have a default export, we normally need to import using the `* as`
// syntax. However, rollup creates a synthetic default module and we thus need to import it using
// the `default as` syntax.
import * as _moment from 'moment';
// tslint:disable-next-line:no-duplicate-imports
import {default as _rollupMoment, Moment} from 'moment';
const moment = _rollupMoment || _moment;
// See the Moment.js docs for the meaning of these formats:
// https://momentjs.com/docs/#/displaying/format/
export const MY_FORMATS = {
parse: {
dateInput: 'MM/YYYY',
},
display: {
dateInput: 'MM/YYYY',
monthYearLabel: 'MMM YYYY',
dateA11yLabel: 'LL',
monthYearA11yLabel: 'MMMM YYYY',
},
};
/** @title Datepicker emulating a Year and month picker */
@Component({
selector: 'datepicker-views-selection-example',
templateUrl: 'datepicker-views-selection-example.html',
styleUrls: ['datepicker-views-selection-example.css'],
providers: [
// `MomentDateAdapter` can be automatically provided by importing `MomentDateModule` in your
// application's root module. We provide it at the component level here, due to limitations of
// our example generation script.
{
provide: DateAdapter,
useClass: MomentDateAdapter,
deps: [MAT_DATE_LOCALE, MAT_MOMENT_DATE_ADAPTER_OPTIONS]
},
{provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
],
})
export class DatepickerViewsSelectionExample {
date = new FormControl(moment());
chosenYearHandler(normalizedYear: Moment) {
const ctrlValue = this.date.value;
ctrlValue.year(normalizedYear.year());
this.date.setValue(ctrlValue);
}
chosenMonthHandler(normalizedMonth: Moment, datepicker: MatDatepicker<Moment>) {
const ctrlValue = this.date.value;
ctrlValue.month(normalizedMonth.month());
this.date.setValue(ctrlValue);
datepicker.close();
}
}
HTML:
<mat-form-field>
<input matInput [matDatepicker]="dp" placeholder="Month and Year" [formControl]="date">
<mat-datepicker-toggle matSuffix [for]="dp"></mat-datepicker-toggle>
<mat-datepicker #dp
startView="multi-year"
(yearSelected)="chosenYearHandler($event)"
(monthSelected)="chosenMonthHandler($event, dp)"
panelClass="example-month-picker">
</mat-datepicker>
</mat-form-field>
我不希望下面的绿色年份选项,想禁用年份
I do not want year option below in green, would like to disable year

Angular Material Date选择器禁用了年份选择
推荐答案
我希望您希望使用DD/MMM之类的日期格式.如果是这样,请在显示和 parse 对象中更改 dateInput ,如下所示
I hope you are expecting date format like DD/MMM. If so then change dateInput in display and parse object like below
dateInput: 'DD/MMM'
希望这会有所帮助.
