Automatically submitting a form in the absence of the user from the page

Question

Automatically submitting a form in the absence of the user from the page

Is it possible to automatically submit a form when the user exits the page?

Here's the code snippet:

<form class="carform" method="get">
 <input type="hidden" name="number_plate" value="{{ car.number_plate }}">
</form>

I want the form to be submitted automatically when the user leaves the page, either by clicking a back button or entering a new URL. This way, the value inside the form can be sent and accessed by other views using the get method.

UPDATE: The goal is for the form to be submitted when the user changes the URL or navigates back using the browser button.

If you want to utilize the window.onbeforeunload event, keep in mind that it will not be triggered when the page is refreshed.

window.onbeforeunload = closeEvent;
function closeEvent(){
    document.getElementById("form").submit();
    return null; // Prevents the confirmation dialog box from appearing
}

Give this a shot:

window.addEventListener('beforeunload', async (event) => {
    event.preventDefault();
    event.returnValue = ''; // Specifically for Chrome

    await executeFormSubmissionFunction();
});

This method is effective when you need to handle page refreshes or back button clicks in the browser.
