建立一個簡單的 Chrome Extension ，按右鍵會撥放選取範圍的文字

manifest.json

{
    "manifest_version" :2,
    "name" : "AudioPlayer",
    "version" : "1.0",
    "description" : "播放英文",
    "icons" :{
        "128" : "icon128.png",
        "48" : "icon48.png",
        "16" : "icon16.png"
    },
    "background" :{
        "scripts" :["eventPage.js"],
        "persistent" : false
    },

    "permissions" : [
        "contextMenus"
    ]
}
eventPage.js
var contextMenuItem = {
    "id" : "AudioPlayer",
    "title" : "Play : %s",
    "contexts" : ["selection"] 
};

chrome.contextMenus.create(contextMenuItem);

chrome.contextMenus.onClicked.addListener(function(clickData){
    if(clickData.menuItemId=="AudioPlayer"){
        var selection = clickData.selectionText;
        var myAudio = new Audio();
        myAudio.src = "https://translate.google.com.vn/translate_tts?ie=UTF-8&q="+selection+"&tl=en&client=tw-ob"; 
        myAudio.play(); 
    }
});

很簡單的創建 audio 並使用 google translate 播放文字
