If you encounter the issue of being unable to assign a custom attribute to the onsubmit of your form in Webflow due to it being blocked as a reserved name, there are alternative solutions you can explore. Here's how you can work around this limitation:

  1. Create a custom code embed:
  • Locate the form element in your Webflow designer.
  • Click on the "+" icon and select Custom Code.
  • Insert the following code in the Head Code section:
    ```html ```
    Replace #your-form-id with the actual ID of the form element you want to target.
  • Replace the comment inside the event listener function with your custom code that will run when the form is submitted.
  1. Use a third-party form processing service:
  • Sign up for a third-party form processing service like Formspree or Formcarry.
  • Follow their instructions to integrate their service with your Webflow form.
  • These services allow you to define custom attributes, such as onsubmit, without any restrictions imposed by Webflow.

Remember to test your implementation thoroughly to ensure that the custom code or third-party service functions as expected. Additionally, keep in mind that custom code embeds may require you to have a Webflow hosting subscription to work properly.
