I am going to use async await instead of AJAX in jsp file. How can I use async/await? This is my code:

function setAcc(){
    var acc_ = getDOM("acc_").value
    AJAX.load({POST: {request: 'set_acc', async: false, acc_: acc_},
        onSuccess: function (result) {
            var objJSON = eval("(function(){return " + result + ";})()");
        go({});
        },
        onError: function (d) {
            alert_g(eval(d));
        }
    });
}
