Question

是否可以使用一个按钮清除/重置表单？表单包含材料datepicker，input，textarea，select和checkboxes。

我的实际代码：

  <form class="example-form" #form="ngForm">
    <button mat-raised-button color="primary (click)="clear(form.value)">Clear</button>
    <mat-form-field class="example-full-width">
      <input matInput placeholder="Name" name="name" ngModel>
    </mat-form-field>
    <mat-form-field>
      <input matInput [matDatepicker]="birthday" [(ngModel)]="geburtsdatum" placeholder="Geburtsdatum" name="geburtsdatum">
      <mat-datepicker-toggle matSuffix [for]="birthday"></mat-datepicker-toggle>
      <mat-datepicker #birthday></mat-datepicker>
    </mat-form-field>
    <mat-checkbox [(ngModel)]="unlimited" name="unbegrenzt">unlimited</mat-checkbox>
    <mat-form-field>
      <mat-select placeholder="Transpondertyp" name="transponderTyp" [(ngModel)]="form.transponderTyp">
        <mat-option>None</mat-option>
        <mat-option *ngFor="let transponderTyp of transponderTyps" [value]="transponderTyp.value">
          {{ transponderTyp.viewValue }}
        </mat-option>
      </mat-select>
    </mat-form-field>
  </form>

Answer 1

<button (click)="form.reset()" >RESET</button>

使用TD表格的reset（）方法

Answer 2

Suhag的解决方案应该可以工作，尽管我总是指定按钮类型，因此它不被视为提交按钮：

<button type="button"(click)="form.reset()">Reset</button>

否则，您可以简单地执行以下操作：

<button type="reset">Reset</button>

Answer 3

您必须在点击事件中清除模型：

 <form class="example-form" #form="ngForm">
    <button mat-raised-button color="primary (click)="clear(form.value)">Clear</button>
    <mat-form-field class="example-full-width">
      <input matInput placeholder="Name" name="name" ngModel>
    </mat-form-field>
    <mat-form-field>
      <input matInput [matDatepicker]="birthday" [(ngModel)]="geburtsdatum" placeholder="Geburtsdatum" name="geburtsdatum">
      <mat-datepicker-toggle matSuffix [for]="birthday"></mat-datepicker-toggle>
      <mat-datepicker #birthday></mat-datepicker>
    </mat-form-field>
    <mat-checkbox [(ngModel)]="unlimited" name="unbegrenzt">unlimited</mat-checkbox>
    <mat-form-field>
      <mat-select placeholder="Transpondertyp" name="transponderTyp" [(ngModel)]="form.transponderTyp">
        <mat-option>None</mat-option>
        <mat-option *ngFor="let transponderTyp of transponderTyps" [value]="transponderTyp.value">
          {{ transponderTyp.viewValue }}
        </mat-option>
      </mat-select>
    </mat-form-field>
   <button (click)="resetForm()" >RESET</button>
  </form>

成分：

resetForm() {
  this.geburtsdatum = '';
  this.unlimited = '';
  this.form.transponderTyp = '';
  this.transponderTyp.value = '';
}
