我正在研究歌剧扩展。该扩展程序有一个弹出窗口，将在其中打开一个网站。我在 popup.html 文件中的“xhr.send()”处收到以下错误，我无法将其删除。
“[4/14/2013 12:51:19 PM] JavaScript - 小部件：//wuid-9ec76e79-06d9-2749-8b7e-b42743de3375/popup.html 内联脚本线程未捕获的异常：ReferenceError：在第 30 行抛出安全违规错误, widget://wuid-9ec76e79-06d9-2749-8b7e-b42743de3375/popup.html 中 fetchGames() 中的第 16 列：xhr.send(); 从第 32 行调用，第 12 列在 widget://wuid-9ec76e79- 06d9-2749-8b7e-b42743de3375/popup.html: fetchGames(); "
我的配置文件如下：
