Unity Web Player不能在.xhtml中運行

Question

當我嘗試使用javascript在xhtml文件內啓動統一網頁播放器時，網頁無法檢測到網頁播放器並要求我下載它。

相同來源（由統一本身生成）與.html工作正常

爲什麼？ ：O

JavaScript不允許在XHTML頁面上使用document.write()。

注有問題的片段：

<script type="text/javascript"> 
<!-- 
var unityObjectUrl = "http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject2.js"; 
if (document.location.protocol == 'https:') 
    unityObjectUrl = unityObjectUrl.replace("http://", "https://ssl-"); 
document.write('<script type="text\/javascript" src="' + unityObjectUrl + '"><\/script>'); 
--> 
</script> 

您可能會注意到有問題的腳本執行非常簡單的操作。如果你知道你的部署，你可以去除它，包括白了結果：

如果部署到HTTP網站：

<script type="text/javascript" src="http://webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject2.js"></script> 

如果部署到HTTPS網站：

<script type="text/javascript" src="https://ssl-webplayer.unity3d.com/download_webplayer-3.x/3.0/uo/UnityObject2.js"></script> 

如果你不知道，理想的解決方法是編輯頁面的DOM，但快速和骯髒的解決方法是edit a node's innerHTML directly。
