<script type="text/javascript">
var main = document.body;
//创建链接
function createa(url,text)
{
var a=document.createElement("a")
a.setAttribute("href","url")
a.innerHTML="text"
a.style.color="red"
main.appendChild(a)
}
// 调用函数创建链接
createa("http://www.imooc.com/","慕课网")
</script>
</body>
</html>这个
a.setAttribute("href","url")和
a.href=url
效果是一样的吗
a.setAttribute("href",url) url 不要加双引号
