為什么按按鈕打不開網(wǎng)頁

<!DOCTYPE html>
<html>
?<head>
? <title> new document </title>?
? <meta http-equiv="Content-Type" content="text/html; charset=gbk"/>??
? <script type="text/javascript">?
? function openWindow()
??? {
??????? var check=confirm("Do you want to open it?");
??????? if(check==true)
??????? {
??????????? var url=prompt("The website?";"http：//idcbgp.cn");
??????????? if(url!=null)
??????????? window.open(url,'width=400px,height=500px,menubar=no,toolbar=no');
??????????? else
??????????? alert("seeyou");
??????? }
??????? else
??????? alert("see you!");
???????
??? }

???
??? // 新窗口打開時彈出確認框，是否打開

??? // 通過輸入對話框，確定打開的網(wǎng)址，默認為 http：//idcbgp.cn/

??? //打開的窗口要求，寬400像素，高500像素，無菜單欄、無工具欄。
