Angular 在5中的反应形式下使用MatDatePicker

我试图使用matdatepicker输入类型作为angular中被动形式的属性。我有组织价值作为反应性表单组的表单控制

这就是我在html中使用它的方式

<input class="inbox-width" matInput formControlName="organizationValue" [matDatepicker]="organizationValue">
<mat-datepicker-toggle matSuffix [for]="organizationValue"></mat-datepicker-toggle>
<mat-datepicker #organizationValue></mat-datepicker>

organizationValue属性shownull，但表单中的其他简单输入类型（如textbox、radio、checkbox）会显示正确的值

被动表单属性未绑定到matdatepicker的原因是什么

将其用作嵌套的被动形式，如图所示：

<form *ngIf="companies" [formGroup]="editForm">
  <div formArrayName="organizations" *ngFor="let organization of editForm.controls.organizations.controls; let i = index;">
    <div formGroupName="{{i}}">
      <div class="row row-margin">
        <label class="col-sm-3">{{organization.get('organizationTitle').value}}</label>
        <div class="col-sm-9">
          <input class="inbox-width" matInput formControlName="organizationValue" [matDatepicker]="organizationValue" [ngClass]="organization.get('organizationBorderError').value"
            (dateInput)="orgValueChange(i)">
          <mat-datepicker-toggle matSuffix [for]="organizationValue"></mat-datepicker-toggle>
          <mat-datepicker #organizationValue></mat-datepicker>
        </div>
      ...

{{organization.get（'organizationTitle'）.value}
...

ı将其嵌套在表单中我无法从主表单获取值

<form *ngIf="companies" [formGroup]="editForm">
  <div formArrayName="organizations" *ngFor="let organization of editForm.controls.organizations.controls; let i = index;">
    <div formGroupName="{{i}}">
      <div class="row row-margin">
        <label class="col-sm-3">{{organization.get('organizationTitle').value}}</label>
        <div class="col-sm-9">
          <input class="inbox-width" matInput formControlName="organizationValue" [matDatepicker]="organizationValue" [ngClass]="organization.get('organizationBorderError').value"
            (dateInput)="orgValueChange(i)">
          <mat-datepicker-toggle matSuffix [for]="organizationValue"></mat-datepicker-toggle>
          <mat-datepicker #organizationValue></mat-datepicker>
        </div>
      ...
