Basic Form Abandonment Script in JavaScript
Here's a basic JavaScript script that tracks form abandonment:

JavaScript
(function() {
  // Variables
  const forms = document.querySelectorAll('form'); // Select all forms on the page
  const abandonmentTime = 3000; // Time in milliseconds before considering abandonment (adjust as needed)

  // Track user activity
  window.addEventListener('beforeunload', (event) => {
    for (const form of forms) {
      if (!form.elementsHaveInteraction()) { // Check if any form element has been interacted with
        event.returnValue = 'Are you sure you want to leave without completing the form?'; // Prompts before leaving
      }
    }
  });

  // Function to check if any form element has been interacted with
  function formElementsHaveInteraction() {
    for (const element of this.elements) {
      if (element.value || element.checked) {
        return true;
      }
    }
    return false;
  }

  // Apply function to all forms
  for (const form of forms) {
    form.elementsHaveInteraction = formElementsHaveInteraction.bind(form);
  }
})();
