当从角度输入中聚焦时触发验证? [英] Fire validation when focus out from input in angular?

问题描述

在我们继续在文本框中输入内容时，电子邮件验证已被触发.我希望当用户将焦点移到文本框之外时触发此验证

Email validation is being fired as we keep typing in textbox. I want this validation to be fired when user focuses out of the textbox

下面是我的代码:

<input class="form-control" pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,3}$"
 name="Email" type="email" [(ngModel)]="model.Email" #Email="ngModel" required>

<div class="red" *ngIf="Email.errors && (Email.dirty || Email.touched)">
     <div [hidden]="!Email.errors.pattern">
         Please enter a valid email.
     </div>
</div>

请建议我如何实现此目标. 预先感谢.

Please suggest me how can I achieve this. Thanks in advance.

推荐答案

从版本6+开始，可以通过updateOn属性设置表单字段验证.

Starting with the version 6+ form field validation can be set via updateOn property.

使用模板驱动的表单:

<input [(ngModel)]="name" [ngModelOptions]="{updateOn: 'blur'}">

具有反应形式:

new FormControl('', {updateOn: 'blur'});

并且如果您设置了验证器:

And if you have validators set:

new FormControl('', {validators: [Validators.required, Validators.email], updateOn: 'blur'})
