在 Angular 2 中更改密码验证

Question

如何验证密码并确认密码必须相同，否则不提交。

<div class="col-md-6 col-md-offset-3">
    <h2>Change Password</h2>
    <form name="form1" (ngSubmit)="f.form.valid && cpass()" #f="ngForm" novalidate>
        <div class="form-group" [ngClass]="{ 'has-error': f.submitted && !password.valid }">
            <label for="password">Password</label>
            <input type="password" class="form-control" name="password" [(ngModel)]="model.password" #password="ngModel" required />
            <div *ngIf="f.submitted && !password.valid" class="help-block">Password is required</div>
        </div>
        <div class="form-group" [ngClass]="{ 'has-error': f.submitted && !confirm-password.valid }">
            <label for="confirm-password">Confirm Password</label>
            <input type="password" class="form-control" name="confirm-password" [(ngModel)]="model.confirm-password" #password="ngModel" required />
            <div *ngIf="f.submitted && !confirm-password.valid" class="help-block">Password is required</div>
        </div>
        <div class="form-group">
            <button class="btn btn-primary">Save</button>
            <a [routerLink]="['/home']" class="btn btn-link">Cancel</a>
        </div>
    </form>
</div>

您需要实现一个自定义验证器来执行诸如确认密码之类的操作
