如何使用Angular Material为特定日期启用/禁用Angular日期选择器

Question

我需要显示开始日期和结束日期的日期，即，如果开始日期是dd/mm/yyyy格式的10/09/2020，则结束日期应为昨天，即09/09/2020，并且应禁用所有剩余日期。

我怎样才能做到这一点？

<mat-form-field color="accent" appearance="fill">
<mat-label>Start Date</mat-label>
<input matInput [matDatepicker]="picker1"  [max]="tomorrow" [formControl]="startDate">
<mat-datepicker-toggle matSuffix [for]="picker1"></mat-datepicker-toggle>
<mat-datepicker #picker1></mat-datepicker>
</mat-form-field>
<mat-form-field color="accent" appearance="fill">
<mat-label>End Date</mat-label>
<input matInput [matDatepicker]="picker2" [min]="today" max="tomorrow" [formControl]="endDate">
<mat-datepicker-toggle matSuffix [for]="picker2"></mat-datepicker-toggle>
<mat-datepicker #picker2></mat-datepicker>
</mat-form-field>

Answer 1

您可以使用过滤器验证。

<mat-form-field class="example-full-width" appearance="fill">
<mat-label>Choose a date</mat-label>
<input matInput [matDatepickerFilter]="myFilter" [matDatepicker]="picker">
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker #picker></mat-datepicker>
</mat-form-field>
import {Component} from '@angular/core';
/** @title Datepicker with filter validation */
@Component({
selector: 'datepicker-filter-example',
templateUrl: 'datepicker-filter-example.html',
})
export class DatepickerFilterExample {
myFilter = (d: Date | null): boolean => {
const day = (d || new Date()).getDay();
// Prevent Saturday and Sunday from being selected.
return day !== 0 && day !== 6;
}
}

我想说一下。英寸

today=new Date();
tomorrow=new Date(this.today.getTime()+24*60*60*1000);

in.html

<input matInput [matDatepicker]="picker" [min]="today" [max]="tomorrow">
