my first extension - add bookmark with a click - HOW TO?

**deckoff** · 08-05-2011, 12:11 PM

I am learning to write javascript and chrome extension. I want an extension that will show a button, and on a click it will add a bookmark folder in the bookmarks. So far so good, got the button, but clicking it adds nothing.
I suppose my javascript is not correct:
here is the code
manifest:

Code:

{
  "name": "My First Extension",
  "version": "1.0",
  "background_page": "background.html",
  "permissions": [
    "tabs", "http://*/*", "bookmarks"
  ],
  "browser_action": {
      "default_icon": "icon.png",
      "name": "HELLO WORLD"
  }
}

Code:

background.html

<html>
<head>
<script>


  function updateIcon() {
    chrome.bookmarks.create({parentId: bookmarkBar.id,
                         title: 'Extension bookmarks'});
                  } 


  chrome.browserAction.onClicked.addListener(updateIcon);
  updateIcon();




);
</script>
</head>
</html>

I suppose it is

Code:

  function updateIcon() {    chrome.bookmarks.create({parentId: bookmarkBar.id,
                         title: 'Extension bookmarks'});
                  }

that is wrong.
Please, advice me and any ggod places for learning javascript. I have read http://code.google.com/chrome/extensions/bookmarks.html already

In updateIcon you use bookmarkBar.id but its never defined. Incase your wondering the id for the bookmarks bar is always 1 so you could replace the bookmarkBar.id with 1.
