Angular - Template-Driven Forms

Consider this Angular code snippet:

this.passwordControl = new FormControl('', [Validators.required, Validators.minLength(6)]);

Which condition correctly shows the error message 'Password too short' only when the password is invalid due to length and the user has interacted with the field?

ApasswordControl.invalid && passwordControl.pristine

BpasswordControl.hasError('minlength') && passwordControl.touched

CpasswordControl.errors.minlength && passwordControl.dirty

DpasswordControl.hasError('required') && passwordControl.touched

Step-by-Step Solution

Solution:

Step 1: Identify how to check specific validation error
Use hasError('minlength') to check if the minlength validator failed.
Step 2: Combine with user interaction check
Use touched to ensure the user has left the input before showing the error.
Final Answer:
passwordControl.hasError('minlength') && passwordControl.touched -> Option B
Quick Check:
Use hasError('minlength') and touched to show length error [OK]

Quick Trick: Use hasError('minlength') with touched for length errors [OK]

Common Mistakes:

MISTAKES
