You're creating a feedback form where users can rate a product. You want to ensure users provide a rating between 1 to 5. How would you validate the input to ensure values are within this range?

  • Use client-side JavaScript to restrict input to values between 1 and 5.
  • Implement server-side validation to check the rating before storing it.
  • Utilize Angular's Validators to create a custom validation rule for the rating field.
  • Allow users to enter any value and provide an error message if it's not within the range after submission.
To validate user input for a rating between 1 to 5 in an Angular form, you would use Angular's Validators to create a custom validation rule (Option 3). This ensures the validation occurs on the client side. Server-side validation (Option 2) is important but doesn't prevent invalid values from being submitted. Option 1 restricts input but doesn't provide feedback, and Option 4 is less user-friendly.
