I am making a simple template-driven form with 'Email Validation' in it (Not by Reactive Forms). So, required, minlength, maxlength are working fine. But, when I try email to be valid, its failing. Can someone help me out?
abc.component.html
<form #customForm="ngForm" (ngSubmit)="alpha(customForm)">
<input type="text" name="firstName" ngModel #firstName ="ngModel" required minlength="3" maxlength="10"><br/>
<div *ngIf="firstName.touched">
<p *ngIf="firstName.errors?.required">First Name is Required!!!</p>
<p *ngIf="firstName.errors?.minlength">First Name minimum 3 characters are required!!!</p>
<p *ngIf="firstName.errors?.maxlength">First Name max length is 10!!!</p>
</div>
<input type="email" name="email" ngModel #email="ngModel" required><br/>
<div *ngIf="email.touched">
<p *ngIf="email.errors?.required">Email is a required field!</p>
<p *ngIf="email.errors?.email">This is not a valid Email!!!</p>
</div>
<button type="submit" [disabled]="customForm.invalid">Submit</button>
</form>
Note: Though required validation of email is taking place, but as the pattern or data entered is not correct, the 2nd validation in email validation div must give error.
Result: (Email valid and its pattern not automatically giving error)
Replace this line
<input type="email" name="email" ngModel #email="ngModel" required>
with
<input type="email" name="email" ngModel #email="ngModel" required email>// add email attribute
You could add an email
attribute to your Email Input. But then that would not in-validate it for something of the pattern xxx@xxx
which I think would not be a valid email in your case.
I suggest you use pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\\.[az]{2,4}$"
instead. Then, where you're showing the error message, you should check for email.errors?.pattern
instead.
Give this a try:
<input
type="email"
name="email"
ngModel
#email="ngModel"
pattern="[a-z0-9._%+-]+@[a-z0-9.-]+\.[a-z]{2,4}$"
required>
<br/>
<div *ngIf="email.touched">
<p *ngIf="email.errors?.required">Email is a required field!</p>
<p *ngIf="email.errors?.pattern">This is not a valid Email!!!</p>
</div>
