angular6 - Angular 6 - 模糊的表单验证

Question

我想验证在 onBlur 中填写的输入，我该怎么做。请帮帮我。

<form class="form-horizontal" role="form" name="form" id="form"
                (ngSubmit)="f.form.valid && onSubmit()"
                #f="ngForm" novalidate>

    <input type="text" class="form-control" placeholder="Social Id"
        [ngModel]="generalUserData.socialId" [maxlength]=12 name="socialId" [minlength]=10
        (blur)="onBlurMethod($event.target.name, $event.target.value ,generalUserData)"
        #socialId="ngModel" [ngClass]="{ 'is-invalid': f.submitted && socialId.invalid }"
        pattern="\d{9}(v|V)|\d{12}" required/>
    <div *ngIf="f.submitted && socialId.invalid" class="invalid-feedback">
        <div *ngIf="socialId?.errors.required">NIC is required</div>
        <div *ngIf="socialId?.errors.minlength">NIC must be at least 10 characters long.</div>
        <div *ngIf="socialId?.errors.pattern">Not valid NIC</div>
        <div *ngIf="socialId?.errors.maxlength">NIC must be less than 12 characters long.</div>
    </div>
</form>

我使用了下面的示例 link然后我想验证模糊我该怎么做。

onBlur() 方法自 Angular 5 起已更改。对于模板驱动的表单，您需要使用以下语法:

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