function?create(url,text)
{
????var?body?=?document.body;
????var?a?=?document.createElement("a");
????a.setAttribute("href",url);
????a.innerHTML?=?text;
????a.style.color?=?"red";
????a.style.text-decoration?=?"none";
????body.appendChild(a);
}

為什么加上a.style.text-decoration = "none";去不掉下劃線，把none的引號(hào)去掉也沒(méi)用
