Submit form when page loads using Javascript

Question

I am designing a page for quiz contest. I need to submit the quiz when users tries to refresh page. I am using JavaScript. Plz help me..!!

function reload() {
            if(localStorage.load == 1) {
                localStorage.load = +0;
                document.getElementById('quesform').submit();
            }
            set();
        }
        function set() {
            if(!localStorage.load || localStorage.load == 0)
                localStorage.load = 1;
        }

I used this code, but it didn't works in chrome. It executes the coding after submitting the form. It sets value to 1 and redirect immediately before displaying question page..

Answer 1

I have removed my previous answer because it is not possible to submit a form when the user tries to leave the page.

You are limited to giving the user the choice of leaving/staying.

The only solution would be to set a cookie containing the form data, so that when the user next visits your page, the data can be retrieved and submitted.
