单击按钮后，Chrome扩展程序无法播放声音吗？

Question

I've created an extension for Google Chrome. There are no errors when uploaded, and the button appears just fine on the extension bar. The extension is supposed to play a sound when clicked, but it does not. Here is my manifest.json file:

{
  "manifest_version": 2,

  "name": "Extension",
  "description": "My Extension",
  "version": "1.0",

  "browser_action": {
    "default_icon": "icon.png",
    "default_title": "Extension",
    "js": ["audio.js"]
  },
  "permissions": [
    "activeTab",
    "https://ajax.googleapis.com/"
  ]
}

and here is my audio.js file:

var myAudio = new Audio();
myAudio.src = "audio.mp3";
myAudio.play();  

I don't see my issue here. Any and all help is appreciated!

Answer 1

1. The toolbar button can only have an html file for the popup, there's no "js" parameter

2. Alternatively use a dynamically loaded event page with a click handler and omit the popup:

   manifest.json:

    "browser_action": { "default_icon": "icon.png", "default_title": "Extension" }, "background": { "scripts": ["event.js"], "persistent": false }, 

   event.js

    chrome.browserAction.onClicked.addListener(function(tab) { var myAudio = new Audio(); myAudio.src = "audio.mp3"; myAudio.play(); }); 

See the official samples for more examples of browserAction API.
