You have a form that has multiple submit buttons for different actions (e.g., Save, Submit for Review). How would you utilize buttons and JavaScript to ensure that each button submits the form differently, and what considerations should you have for user experience and data integrity?
- Assign different names or values to the buttons and use JavaScript event listeners to handle different submit actions.
- Place each button in a different form and duplicate the input fields.
- Use only one button and prompt users to choose an action via a dropdown.
- Use the same name and value for all buttons and distinguish actions based on button color.
Different actions can be handled by giving each submit button a unique name or value. By using JavaScript event listeners, you can detect which button was clicked and handle the form submission accordingly. This approach ensures data integrity by allowing specific actions to be taken based on the user's choice. It also enhances user experience by providing clear, direct actions without redundant steps or confusion.
