为何用alink.innerHTML=text就可以，而用alink.setAttribute("value",text)不行呢？
<!DOCTYPE HTML><html><head><meta http-equiv="Content-Type" content="text/html; charset=utf-8"><title>无标题文档</title></head><body><script type="text/javascript">var main = document.body;//创建链接function createa(url,text){ var alink=document.createElement("a"); alink.setAttribute("href",url);// alink.setAttribute("value",text); alink.innerHTML=text; alink.style.color="blue"; main.appendChild(alink); }// 调用函数创建链接createa("http://www.imooc.com","慕课网");</script> </body></html>
