javascript : 폼(form)과 파라미터(hidden)를 동적으로 생성하여 post로 전송(submit)

function goBuyDetail(){

var formObject?= document.createElement(“form”);
formObject.setAttribute(“method”,”post”);
formObject.action = “/MyPage.do?cmd=listMyBuyPrdDetail”;
document.appendChild(formObject);

var buyIdObject = document.createElement(“input”);
buyIdObject.setAttribute(“type”,”hidden”);
buyIdObject.setAttribute(“name”, “hidden이름” );
buyIdObject.setAttribute(“value”,?”hidden값” );
formObject.appendChild(buyIdObject);

formObject.submit();
}
