Answer 1

Submit button always send request to server , so default it refresh the page. To overcome this issue, you can define it as simple button Or you have below solutions in Jquery Click event code:

(1) return false; //at last statement of your code which not allow page to refresh
(2) use event.PreventDefault()

Answer 2

window.onbeforeunload gets triggered in case of submit too, so set location.href to refresh parent page just before window.close() .

function closeMe() {
        window.opener.location.href = '../ContentPages/QuoteBuy.aspx';
        window.close();
    }

    window.onload = function () {
        window.opener.document.body.disabled = true;
    }

    window.onbeforeunload = function () { myUnloadEvent(); }
    function myUnloadEvent() {
        //Do your work
        //window.opener.location.href = '../ContentPages/QuoteBuy.aspx';
    }
