I want to stop the navigation of a form after form submit. For this I am trying to write a script in customHTML.

So for this I am trying to do the form submission manually by using the following code : 

<script type="text/javascript">
            document.addEventListener("DOMContentLoaded", function(event) {
                var submitButton = document.querySelector("[type='submit']");
                if (submitButton) {
                    submitButton.addEventListener("click", function(event) {
                        event.preventDefault();
                        // Add custom logic here
                        // ...
                        // Submit the form manually when ready
                        joget.submitForm();
                        // Prevent form navigation
                        event.stopPropagation();
                    });
                }
            });
        </script>

This is giving me error that joget is not defined. Also If I try to include joget.js and joget.min.js file (which should be automatically included) by API, I am getting error as it is unable to find these two files :

/jw/web/js/joget.js

Please help. Thanks in Advance
