我正在开发一个 Firefox 扩展，我希望它在事件发生时播放通知声音。然而，尽管遵循了从 Firefox 扩展的数据目录播放音频 https://stackoverflow.com/questions/16449813/play-audio-from-firefox-extensions-data-directory，声音不播放。它存储在我的数据目录中。这是我的代码：
var pageworker = require ("sdk/page-worker");
let { setTimeout } = require("sdk/timers"); //setTimeout is not enabled by default in ff extensions
function playSound(sound){
console.log("playing sound: "+sound);
var soundPlayer = pageworker.Page({
contentURL: data.url("blank.html"),
contentScript: "new Audio('notification-1.mp3').play();console.log('the audio did run')",//This is where it should play, but it doesn't, even if I remove the console.log
//The script does work if I type it into the javascript console, but replace the file name with a file:/// URL
});
setTimeout(function(){soundPlayer.destroy();},5000);//destroy the sound player after 5 seconds
}
但尽管两者控制台日志被调用，没有任何音频播放。
这在 XPI 中和使用 cfx 时都是如此。
正如评论中所述，尝试在contentScript string:
"new Audio("+data.url("notification-1.mp3")+").play();"
