setAttribute("color","red");和style.color="red"效果为什么不一样？

源自：9-16 创建元素节点createElement

<!DOCTYPE HTML>

<html>

<head>

<title>无标题文档</title>

</head>

<body>

var main = document.body;

//创建链接

function createa(url,text)

{

var newnode=document.createElement("a");

newnode.innerHTML=text;

newnode.href=url;

//newnode.style.color="red"

newnode.setAttribute("color","red"); //不能实现文字红色效果

main.appendChild(newnode)

}

// 调用函数创建链接

createa("http://www.imooc.com/","慕课网");
