How can the "button" element be used for client-side form validation before submission?
- By setting the "type" attribute of the button to "validate".
- By specifying the "required" attribute on the button.
- By using JavaScript to trigger validation functions when the button is clicked.
- By using the "pattern" attribute on the button.
The "button" element by itself doesn't validate form input. However, when combined with JavaScript, it can trigger client-side validation functions when clicked. For example, you can attach an event listener to the button that checks all input fields for validity before allowing the form to submit. If validation fails, the event can be canceled, preventing submission, and providing feedback to the user. This provides an immediate response without needing to communicate with the server, enhancing user experience.
