Question

我用角形材料创建了一个模态。我面临的问题是我无法导航到模式的第二部分。

我的代码：

dialog-overview-example.html

<ol>
  <li>
    <mat-form-field>
      <input matInput [(ngModel)]="name" placeholder="What's your name?">
    </mat-form-field>
  </li>
  <li>
    <button mat-raised-button (click)="openDialog()">Pick one</button>
  </li>
  <li *ngIf="animal">
    You chose: <i>{{animal}}</i>
  </li>
</ol>

dialog-overview-example.ts

import {Component, Inject} from '@angular/core';
import {MatDialog, MatDialogRef, MAT_DIALOG_DATA} from '@angular/material/dialog';

export interface DialogData {
  animal: string;
  name: string;
}

/**
 * @title Dialog Overview
 */
@Component({
  selector: 'dialog-overview-example',
  templateUrl: 'dialog-overview-example.html',
  styleUrls: ['dialog-overview-example.css'],
})
export class DialogOverviewExample {

  animal: string;
  name: string;

  constructor(public dialog: MatDialog) {}

  openDialog(): void {
    const dialogRef = this.dialog.open(DialogOverviewExampleDialog, {
      width: '250px',
      data: {name: this.name, animal: this.animal}
    });

    dialogRef.afterClosed().subscribe(result => {
      console.log('The dialog was closed');
      this.animal = result;
    });
  }

}

@Component({
  selector: 'dialog-overview-example-dialog',
  templateUrl: 'dialog-overview-example-dialog.html',
})
export class DialogOverviewExampleDialog {

  constructor(
    public dialogRef: MatDialogRef<DialogOverviewExampleDialog>,
    @Inject(MAT_DIALOG_DATA) public data: DialogData) {}

  onNoClick(): void {
    this.dialogRef.close();
  }

}

dialog-overview-example-dialog.html

<h1 mat-dialog-title>Hi {{data.name}}</h1>
<div mat-dialog-content>
  <p>What's your favorite animal?</p>
  <mat-form-field>
    <input matInput [(ngModel)]="data.animal">
  </mat-form-field>
</div>
<div mat-dialog-content>
  <p>My favorite Animal</p>
  <mat-form-field>
    <input matInput [(ngModel)]="data.animal">
  </mat-form-field>
</div>
<div mat-dialog-actions>
  <button mat-button (click)="onNoClick()">No Thanks</button>
  <button mat-button [mat-dialog-close]="data.animal" cdkFocusInitial>Next</button>
</div>

从上面的代码中可以看到，我使用了两个div mat-dialog-content。我要实现的功能是，当我单击NEXT按钮时，内容应该切换到第二个Mat-dialog，并且当对话框内容切换到第二个时，页脚中的按钮应该更改为Confirm而不是next。。有人可以帮我吗我已经对此进行了尝试，但无法解决此问题。如果有人可以指导我，这将是有帮助的。
