How could I make an extension that open a url when the icon is clicked?

There will be an icon in Chrome's extension bar, I'd like to ope开发者_C百科n a link in a new tab when the icon is clicked(instead of popup a popup page). How could I do that?

In your background page:

chrome.browserAction.onClicked.addListener(function() {
  chrome.tabs.create({url: "http://www.google.com"});
});

Google documentation for

• chrome.browserAction.onClicked
• chrome.tabs.create
