我的代碼錯在哪里呀？？？
<!DOCTYPE? HTML>
<html >
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>函數</title>
<script type="text/javascript">
function compare(a,b){
//定義函數
if(a>b){
???
return a;
???
}
???
else if(a==b){
???????
return "一樣大";
??? }
??
?else（a<b){
??????? return b;
??
?}
}
?
document.write(" 5 和 4 的較大值是:"+"compare(5,4)"+"<br>");
?
document.write(" 6 和 3 的較大值是:"+"compare(6,3)");
</script>
</head>
<body>
</body>
</html>
上面是我寫的代碼，和貌似和答案一模一樣，可為什么瀏覽器是空白的？

else（a<b){else不能帶()作判斷，其實這里不用作判斷了，剩下的也只能是a<b
document.write("?5?和?4?的較大值是:"+"compare(5,4)"+"<br>"); ?? document.write("?6?和?3?的較大值是:"+"compare(6,3)");調用函數不需要加引號
修改后的全代碼

謝謝了，親
