如何在Angular 4材質的Stepper中提交表單？

Question

如何在角形材料的步進器中提交表單數據。 我正在從角度材料https://material.angular.io/components/stepper/examples中查看示例。 在問這個問題之前，我做了很多谷歌搜索，但沒有找到任何答案。

<mat-horizontal-stepper [linear]="isLinear" #stepper="matHorizontalStepper">
  <mat-step [stepControl]="firstFormGroup">
    <form [formGroup]="firstFormGroup">
      <ng-template matStepLabel>Fill out your name</ng-template>
      <mat-form-field>
        <input matInput placeholder="Last name, First name" formControlName="firstCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step [stepControl]="secondFormGroup">
    <form [formGroup]="secondFormGroup">
      <ng-template matStepLabel>Fill out your address</ng-template>
      <mat-form-field>
        <input matInput placeholder="Address" formControlName="secondCtrl" required>
      </mat-form-field>
      <div>
        <button mat-button matStepperPrevious>Back</button>
        <button mat-button matStepperNext>Next</button>
      </div>
    </form>
  </mat-step>
  <mat-step>
    <ng-template matStepLabel>Done</ng-template>
    You are now done.
    <div>
      <button mat-button matStepperPrevious>Back</button>
      <button mat-button (click)="stepper.reset()">Reset</button>
    </div>
  </mat-step>
</mat-horizontal-stepper>

我已經填寫了兩種表格。 但是之后，我沒有得到如何獲取/提交表單數據。

謝謝你的幫助... ：-）

給提交按鈕和ngSubmit到表單，在Stepper里面有表單

      <button mat-raised-button (click)="isLinear = true" id="toggle-linear">Enable linear mode</button>

<mat-horizontal-stepper [linear]="isLinear" #stepper="matHorizontalStepper">
  <mat-step [stepControl]="firstFormGroup">
    <form [formGroup]="firstFormGroup" (ngSubmit)="form1()" #formone="ngForm">
      <ng-template matStepLabel>Fill out your name</ng-template>
      <mat-form-field>
        <input matInput placeholder="Last name, First name" formControlName="firstCtrl" required>
      </mat-form-field>
      <div>
        <button type="button" mat-button matStepperNext>Next</button>
        <button type="submit" mat-button>submit</button>
      </div>
    </form>
  </mat-step>
  <mat-step [stepControl]="secondFormGroup">
    <form [formGroup]="secondFormGroup" (ngSubmit)="form2()" #formtwo="ngForm">
      <ng-template matStepLabel>Fill out your address</ng-template>
      <mat-form-field>
        <input matInput placeholder="Address" formControlName="secondCtrl" required>
      </mat-form-field>
      <div>
        <button type="button" mat-button matStepperPrevious>Back</button>
        <button type="button" mat-button matStepperNext>Next</button>
         <button type="submit" mat-button>submit</button>
      </div>
    </form>
  </mat-step>
  <mat-step>
    <ng-template matStepLabel>Done</ng-template>
    You are now done.
    <div>
      <button mat-button matStepperPrevious>Back</button>
      <button mat-button type="button" (click)="stepper.reset()">Reset</button>
      <button mat-button type="button" (click)="formone.ngSubmit.emit();formtwo.ngSubmit.emit()">
        submit
        </button>
    </div>
  </mat-step>
</mat-horizontal-stepper>

零件

form1(){
    console.log(this.firstFormGroup.value);
  }

  form2(){
    console.log(this.secondFormGroup.value);
  }
