chrome.tabs.create - callback function never called

Question

I want to create a new tab using Chrome Extension and when tab is loaded to show tab.id. Page is loaded but callback function is not worked (alert with tab.id is now showed).

The background.js file:

chrome.tabs.create({'url': 'http://www.google.com'}, function(tab){ alert(tab.id) })

The manifest.json file:

 {
     "name": "Test",
     "version": "1.0",
     "description": "Test plugin",
     "browser_action": {
         "default_popup": "popup.html",
         "default_icon":"icon.png"
     },
     "background": {
         "scripts": ["background.js"]
     },
     "manifest_version":2,
     "permissions": [
          "tabs",
          "http://*.facebook.com/*",
          "http://*.google.com/*",
          "storage"
     ]
}

The popup.html file:

<html>
  <head>
    <title>Test tabs</title>
  </head>
  <body>
    <script type="text/javascript" src=/background.js"></script>
  </body>
</html>

What can be a problem?

Your code must be located in background pages.

This is in the manifest.json file:

"background" : {"scripts" : ["background_script.js"] }

or

"background" : {"page" : "background_page.html" }

You need to use absolute path when you referring to the file inside background page:

<script type="text/javascript" src="/background.js"></script>

Do you get any exceptions/errors while you run your extension? – P̲̳x͓L̳ Apr 02 '14 at 21:13
There are no exceptions appeared on extensions page – shtkuh Apr 02 '14 at 21:18
maybe something wrong with my popup.html? added it now – shtkuh Apr 02 '14 at 21:40
background.js should be loaded from background.html or something like that? – shtkuh Apr 02 '14 at 21:43
Still does not work.. Something is still missing. Did you tried with exact those 3 files? Sorry to bother you again and thank for your help – shtkuh Apr 03 '14 at 08:51
Yes, I tried with those files and works fine. Do you have latest version of the Google Chrome? – P̲̳x͓L̳ Apr 03 '14 at 09:09
Tried it again and it works now with html fix:) Did not paid attention that script is running only once on browser load – shtkuh Apr 03 '14 at 09:32

I think callback function is executed in another context, and alert will not work. Try to open background page and DevTools and use console.log(tab.id) for see tab ID.

Can you please explain what is the "another context"? There are some restrictions of what callback function can do? – shtkuh Apr 03 '14 at 08:59

@shtkuh Chrome extensions scripts has 3 context of executing: -background scripts (wxecuting into extension)
-content scripts ( can read and modify the DOM for the displayed web page)
- injected scripts

Here's my solution:
chrome.tabs.create({url: URL, selected: false}, function(tab) { alert(tab.id) })

Not sure whether this is what you expected but the alert would work!
