歌剧扩展错误"Uncaught exception: ReferenceError: Security violation"

我正在做一个歌剧扩展。扩展有一个弹出窗口，将打开一个网站在它。我得到下面的错误在"xhr.send()"在popup.html文件，我无法删除它。

"[4/14/2013 12:51:19 PM] JavaScript -部件://wuid - 9 - ec76e79 - 06 - d9 - 2749 - 8 b7e b42743de3375/popup.html内联未捕获的异常:ReferenceError:安全违规在fetchGames()中的第30行，第16列抛出错误部件://wuid - 9 - ec76e79 - 06 - d9 - 2749 - 8 b7e b42743de3375/popup.html:xhr.send ();从widget的第32行第12列调用://wuid-9ec76e79-06d9-2749-8b7e-b42743de3375/popup.html:fetchGames ();"

请帮我把它去掉

在获取数据的文件头添加以下内容:

Access-Control-Allow-Origin: *

在config.xml文件中添加这一行:允许任何域的httprequest前选项卡，这解决了问题，如果问题仍然存在，打开opera浏览器选项卡"opera:config"并选择"Users Prefs"并勾选"允许文件XMLHttpRequest"并重新启动。如果有问题，我可以给你我的opera扩展工作正常…
