在Firefox中播放声音附加 [英] Playing a sound in a Firefox add-on

问题描述

我想创建一个简单的插件，将发挥不同的MP3录音，每次用户双击一个网页，他正在访问一个字，并选择从上下文菜单中一个特殊的选项。

I would like to create a simple add-on that would play a different MP3 recording every time the user double clicks a word in a webpage he is visiting and selects a special option from the context menu.

的MP3文件位于远程服务器上。通常我会用JavaScript + Flash来播放MP3文件。在Firefox插件，但是，我无法加载外部脚本由于某种原因（播放声音工作正常，如果它是加载脚本的网页本身，但当然我需要它与每一个网站，而不仅仅是工作包括该脚本的那些）。

The MP3 files are located on a remote server. Normally I would use JavaScript+Flash to play the MP3 file. In a Firefox add-on, however, I'm unable to load external scripts for some reason (playing the sound works fine if it's the webpage itself that loads the scripts, but of course I need it to work with every website and not just the ones that include the script).

那么，在Firefox中发挥远程MP3文件，最简单的方法附加使用JavaScript？

So what's the easiest way to play a remote MP3 file in a Firefox add-on using JavaScript?

推荐答案

这可能不能完全解决你的问题，因为我不相信它播放MP3，但我不能肯定。

This may not entirely solve your question, as I don't BELIEVE it plays MP3s, but I'm not certain.

Firefox拥有nsISound，我知道可以播放远程WAV文件，因为我已经测试并证明了这一点。

Firefox has nsISound, which I KNOW can play remote WAV files, as I've tested and proved it.

您可能想测试自己，看看它是否会导致你靠近一点！

You may want to test it for yourself and see if it leads you a little closer!

var ios = Components.classes['@mozilla.org/network/io-service;1'].getService(Components.interfaces.nsIIOService);
var sound = ios.newURI("http://www.yoursite.com/snds/haha.wav", null, null); 
var player = Components.classes["@mozilla.org/sound;1"].createInstance(Components.interfaces.nsISound);

player.play(sound);

祝你好运，我希望这至少可以让你靠近！

Good luck, I hope this at least gets you close!
