一年多前 google 自己推出的右鍵搜圖 Search by Image 套件,
沒想到今天已經變成內建的了(新版Chrome 按右鍵找圖)
所以今天就來寫一下右鍵選單(ContextMenus)吧

manifest.json

{
   "manifest_version": 2,
   "name": "ironman6",
   "version": "1.0",
   "background": {
      "scripts": ["background.js"]
   },
   "permissions": [
      "contextMenus"
   ]
}

background.js

for (var i = 1; i < 7; i++) {
    chrome.contextMenus.create({
        "title": "Day " + i,
        "contexts":["all"],
        "onclick": genericOnClick
    });
}

function genericOnClick(info, tab) {
    var output = [];
    for(item in info){  
        output.push(item + ' : ' + info[item]);  
    }
    for(item in tab){  
        output.push(item + ' : ' + tab[item]);  
    } 
    chrome.tabs.create({  
        url: 'data:text/html;charset=utf-8,' + '<p>' + output.join('<p/><p>') + '</p>'  
    })
}
