这是我的 HTML 代码, `
<mat-form-field class="datepicker">
<mat-label>Pick a date</mat-label>
<input matInput
#resultPickerModel="ngModel"
[matDatepicker]="resultPicker"
[(ngModel)]="date"
[min]="minDate"
[max]="maxDate"
(input)="ageFromDateOfBirthday($event)">
<mat-datepicker-toggle matSuffix [for]="resultPicker"></mat-datepicker-toggle>
<mat-datepicker #resultPicker>
</mat-datepicker>
<mat-error *ngIf="resultPickerModel.hasError('matDatepickerParse')">
"{{resultPickerModel.getError('matDatepickerParse').text}}"
is not a valid date!
</mat-error>
<mat-error *ngIf="resultPickerModel.hasError('matDatepickerMin')">
Minimum date should be {{minDate | date }}</mat-error>
<mat-error *ngIf="resultPickerModel.hasError('matDatepickerMax')">
Maximum date should be {{maxDate | date }}
</mat-error>
</mat-form-field>
</mat-grid-tile>
<mat-grid-tile>
<mat-form-field appearance="fill" class="age">
<mat-label>Age</mat-label>
<input type="number" matInput >
</mat-form-field>
</mat-grid-tile>`
在这里,当我们在日期选择器中选择年龄时,我必须在输入文本框中提供AGE。 请让我知道任何解决方案。
也许这段代码可以帮助你:
getAge(birthDate: Date): number {
const ageTilNowInMilliseconds = Date.now() - birthDate.getTime();
const ageDate = new Date(ageTilNowInMilliseconds);
return Math.abs(ageDate.getUTCFullYear() - 1970); // Because computers count the today date from the 1st of January 1970
}
希望对您有帮助。
