var mian = document.body;
function createa(url,text)?{ ? ?
var alink=document.createElement("a"); ? ?
alink.setAttribute("href",url); ? ?
alink.setAttribute("value",text); ? ?
alink.setAttribute("color","purple"); ? ??
main.appendChild(alink); ? }?
// 調用函數創建鏈接 ? ?
createa("http://www.xianlaiwan.cn","慕課網");?
//哪里出問題了呢？

var mian = document.body; //你下面調用的是main ,而你這里寫成了mian
function createa(url,text)?{ ? ?
var alink=document.createElement("a"); ? ?
alink.setAttribute("href",url); ? ?
alink.setAttribute("value",text); ?? //文本內容用innerHTML?? alink.innerHTML=text;???
alink.setAttribute("color","purple"); ? ? //顏色要用.style ? ? alink.style.color = "purple" ;
main.appendChild(alink);?
