如何禁用角材质日期选取器范围的过去日期

Question

下面是模板和组件文件的示例。使用[min]属性不会绑定到模板上的表单输入。如有任何帮助，我将不胜感激。

<mat-form-field>
<mat-label>Enter a date range</mat-label>
<mat-date-range-input [formGroup]="range" [rangePicker]="picker">
<input matStartDate formControlName="start" placeholder="Start date" [min]="minDate">
<input matEndDate formControlName="end" placeholder="End date">
</mat-date-range-input>
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-date-range-picker #picker></mat-date-range-picker>
<mat-error *ngIf="range.controls.start.hasError('matStartDateInvalid')">Invalid start date</mat-error>
<mat-error *ngIf="range.controls.end.hasError('matEndDateInvalid')">Invalid end date</mat-error>
</mat-form-field>

import {Component} from '@angular/core';
import {FormGroup, FormControl} from '@angular/forms';
/** @title Date range picker forms integration */
@Component({
selector: 'date-range-picker-forms-example',
templateUrl: 'date-range-picker-forms-example.html',
})
export class DateRangePickerFormsExample {
minDate: Date;
range = new FormGroup({
start: new FormControl(),
end: new FormControl()
});
constructor() {
const currentYear = new Date().getFullYear();
this.minDate = new Date(currentYear - 0, 0, 1);
}
}

Answer 1

您正在使用mat-date-range-input，您不能将最小和最大应用于输入。你需要把它应用到mat-date-range-input

<mat-date-range-input [formGroup]="range" [rangePicker]="picker" [min]="minDate">
...
</mat-date-range-input>

Answer 2

set minDate为currentDate

constructor() {
this.minDate = new Date();
}
