| Dernières réponses | |  Validating a web form using JavaScript ensures that users input data correctly before submission. Start by adding an event listener to the form’s submit event. Use JavaScript to check each field, like ensuring email format or that required fields aren’t empty. If a condition fails, display an error message and prevent form submission using event.preventDefault(). This real-time validation improves user experience and data accuracy. For complex validations, regular expressions can be used. Struggling with your form validation code?
