如何在不按下按钮的情况下(没有表格)如何验证电子邮件地址中包含@符号和点。我将不胜感激。

<mat-form-field class="example-full-width">
  <input matInput placeholder="Favorite food" value="Sushi">
</mat-form-field>

您可以使用模式并定义正则表达式来验证电子邮件地址,

<input matInput placeholder="Favorite food" [(ngModel)]="enterEmail" name="myEmail" pattern="[a-zA-Z0-9.-_]{1,}@[a-zA-Z.-]{2,}[.]{1}[a-zA-Z]{2,}" required>

我正在使用Angular 8,它的指令为EmailValidator

与ngModel一起使用,如下所示:

<input type="email" name="email" ngModel email>
<input type="email" name="email" ngModel email="true">
<input type="email" name="email" ngModel [email]="true">

您也可以通过这种方式进行验证

在您的模板(.html文件)中:

<form
  [formGroup]="userForm"
  #formDirective="ngForm"
  (ngSubmit)="onFormSubmit()"
>
  <div class="form-control">
    <mat-form-field appearance="outline" class="form-field">
      <mat-label>Email Address</mat-label>
      <input
        type="text"
        matInput
        formControlName="email"
        class="form-input-field"
        pattern="[a-zA-Z0-9.-_]{1,}@[a-zA-Z.-]{2,}[.]{1}[a-zA-Z]{2,}"
      />
      <mat-error *ngIf="userForm.get('email').hasError('required')"
        >Email is required</mat-error
      >
      <mat-error *ngIf="userForm.get('email').hasError('email')"
        >Please enter a valid email address
      </mat-error>
    </mat-form-field>
  </div>
</form>

在您的组件(.ts文件)中:

userForm = new FormGroup({
  email: new FormControl('', [Validators.required, Validators.email]),
});
