Troubleshooting Form Input Handling in JavaScript

Understanding the Problem

In the JavaScript snippet you provided, the process of retrieving form values is attempted outside of the event handler. Here's the original code structure that leads to the issue:

Why Does This Happen?

The reason this setup fails is simple: When you retrieve the values of the form inputs in this manner, you're doing so during the initial execution of the script—before the user interacts with the form. As a result, these variables only capture the values present at that moment, which will always be empty since the form has not been submitted yet.

Solution: Move Variable Assignments into the Event Handler

To fix this issue, you need to retrieve the values of the form inputs right before the form is about to be submitted. This ensures you capture the latest input data. Here's an updated version of your JavaScript code:

Key Changes

Moved Variable Declarations: By relocating the variable assignments to within the onsubmit event handler, we ensure that values are captured right at the moment the user submits the form.

Conclusion

By making these changes, you should now be able to reliably access the input values and successfully process the user's sign-up requests. This approach not only resolves the issue but also enhances the overall reliability of your form handling. Remember, always retrieve input values at the moment of form submission to ensure you're working with the most current data.
