"chrome.tabs.create" works, but "chrome.tabs.update" does not

Question

function doit() { alert(3); // Statement 1 // chrome.tabs.create({url:"http://www.google.com"}); // Statement 2 // chrome.tabs.update({url:"http://en.wikipedia.org"}); alert(4); } chrome.browserAction.onClicked.addListener(doit); 

---

When the script works as is, I get JS 3 and 4 warnings. OK.

When I comment in instruction 1 and run the script, I get a JS warning of 3, then Google opens on a new active tab, then I get a JS warning of 4. As expected.

When I comment on expression 1 and comment in statement 2, I get a JS warning of 3, and that is.

According to http://code.google.com/chrome/extensions/tabs.html#method-update , I don’t need to pass the tabId object because it "defaults to the selected tab of the current window". The url object is defined as the “URL to go through the tab,” as I noticed when I ran chrome.tabs.create in instruction 1.

Why is my chrome.tabs.update instruction not working?

Answer 1

You must specify the tabId parameter. Set to null if you want to use the default settings. Otherwise, the following error occurs:

Error in event handler for 'browserAction.onClicked': Error: Invalid value for argument 1. Expected "integer", but received an "object".

This message is logged on the background page . To access this console, follow these steps in this answer .

Corrected code: chrome.tabs.update(null, {url:"http://en.wikipedia.org"});

Answer 2

You must specify which tab (tab.id) you want to update.

 chrome.tabs.update(id,{url:"http://en.wikipedia.org"});
