Users are experiencing issues where they complete a form but receive an error stating that required fields are not filled out. How can you ensure that users are alerted to missed fields before submitting?

  • Add the required attribute to necessary input fields. 
  • Ask users to double-check their entries before hitting submit. 
  • Manually review each submission for missing fields. 
  • Use JavaScript alerts for each field when the user tries to submit. 
The required attribute in HTML ensures that the browser prompts the user to fill in the field before allowing form submission. It's a native way to enforce field completion without relying on additional scripts or manual checks. While JavaScript can achieve similar functionality, using the required attribute is more straightforward and doesn't depend on users having JavaScript enabled.
