Below is the code I've written:
***<input type="text" placeholder="First Name" name="firstName1" [(ngModel)]="firstName" #firstName1="ngModel" required pattern="^[a-z0-9_-]{8,15}$" >***
If you're looking to match a string that contains only alphabets, you can utilize the following regular expression:
/^[A-Za-z]+$/
This regex pattern will ensure that the input consists of alphabetical characters only.
