javascript - chrome.windows undefined for Chrome Extension - Stack Overflow

I'm building a Chrome extension that allows the user to manage open tabs for an application (website). The manifest is:

{
    "manifest_version": 2,
    "name": "AT Tabs",
    "version": "0.1",
    "permissions": ["activeTab", "tabs"],
    "content_scripts": [{
        "matches": ["<all_urls>"],
        "js": ["main.js"]
    }]
}

But when I do this in the main.js file:

console.log(chrome.windows);

I get undefined in the console... Any ideas why? I have both tabs and activeTab as permissions and the extension is being run in the developer mode.

chrome.windows will not be available in your main.js because it is an injected content script.

Only your background/event pages JavaScript has access to chrome.windows. You will need to use message passing from your content script to your background script to trigger the window actions you want.

For instance, to create a window from an content script, your extension may look something like this:

Manifest:

{
  ...
  "background": {
    "scripts": ["eventPage.js"],
    "persistent": false
  },
  ...
}

main.js:

chrome.runtime.sendMessage({
    action: 'createWindow',
    url: 'http://google.com'
  },
  function(createdWindow) {
    console.log(createdWindow);
  });

eventPage.js:

chrome.runtime.onMessage.addListener(function(request, sender, sendResponse) {
  if (request && request.action === 'createWindow' && request.url) {
    chrome.windows.create({url: request.url}, function (win) {
      sendResponse(win);
    });
  }
});
