Give submit button and ngSubmit to form where you have forms inside Stepper
将提交按钮和 ngSubmit 提供给表单，其中 Stepper 中有表单
<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>
