angular - 面临问题 'A MatDatepicker can only be associated with a single input.' Angular 8 Material

Question

<input matInput placeholder="DD/MM/YYYY" [matDatepicker]="picker" class="modifyDate" NoSpecialChar ngModel #dateCtrl="ngModel" name="datepicker" (click)="picker.open()" id="dtDeparture" required>
<mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
<mat-datepicker #picker></mat-datepicker>
<mat-error *ngIf="dateCtrl.errors?.required && dateCtrl.touched">Choose a Date       
</mat-error>

<input matInput placeholder="DD/MM/YYYY" [matDatepicker]="picker1" NoSpecialChar class="modifyDate" [(ngModel)]="inputEndDate" name="dtArrival" (click)="picker1.open()" id="dtArrival" required>
<mat-datepicker-toggle matSuffix [for]="picker1"></mat-datepicker-toggle>
<mat-datepicker #picker1></mat-datepicker>

正如您在上面看到的，我们为日期输入即picker1 和picker 提供了唯一的ID。问题仍然存在“MatDatepicker 只能与单个输入相关联。”不知从何而来。我需要帮助。我在谷歌和stackover上搜索过，但没有帮助

试试这个用这个替换你的代码并尝试

<mat-form-field>
  <input matInput [matDatepicker]="picker">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

<mat-form-field>
  <input matInput [matDatepicker]="picker1">
  <mat-datepicker-toggle matSuffix [for]="picker1"></mat-datepicker-toggle>
  <mat-datepicker #picker1></mat-datepicker>
</mat-form-field>

指的是包装的组件(例如输入、文本区域、选择等)
