页面上的JavaScript保存表单卸载

Question

I'm trying to automatically save a form when leaving a page with JavaScript by using the following code

$(window).unload( function() {
    $("#registration-patient-form").submit();
});

Yet, somehow the form does not get submitted and I'm simply redirected to the page I'm navigating to. Any idea on how to accomplish this?

You should do it every x seconds. Because user can close the page at unexpected time. 1) Create a function and call it every 1 second. 2) Check the data if it is changed. 3) If data is changed, submit
