问如何将填写了一半的表单数据发送到服务器？

EN

function sendAbandoned() {
        var now = new Date();
        now = Math.floor(now / 1000);

        if ((now - lastUpdate) < 10) {
            // make sure doesn't send too many "updates"
            return false;
        }


        lastUpdate = now;
        var formArr=$("form[name='formName']").serializeArray();

        $.post('/path/to/abandoned/handler.php',
        formArr);
    }


    $("form[name='formName'] input").blur(function () {
        sendAbandoned();
    });
