An admin page with metaboxes and custom fields works fine, but when the user forgets to click "update" there is no warning "Leave Site? Changes you made may not be saved.". This warning only works on changes of title and main content but not on the custom fields.

Does WordPress provide in a standard way to track changes on input fields and trigger the warning on page-leave?
