[crx] Example Needed - chrome.tabs.update

[rc]

Hello-

I've added "permissions": [ "tabs"] to the manifest.json file.

In my code I've attempted to have the following activate in javascript
when a link is click and neither work.
chrome.tabs.update(0, {url: 'http://www.google.com'});
chrome.tabs.update(1, {url: 'http://www.google.com'});

Does anyone have a working example of chrome.tabs.update they can
share?

Thanks,
Rob

Depends on what you want to do. You cant bass 0 or 1 as tab ID, you
must get them from chrome.tabs.getAllInWindow,
chrome.tabs.getSelected, or a callback on tabs events.

Here are two snipptes used in my extension:

------------

chrome.tabs.getAllInWindow(
undefined,
function(tabs) {
for (var i = 0, tab; tab = tabs[i]; i++) {
if (tab.url && isUrl(tab.url, getUrl())) {
chrome.tabs.update(tab.id, {url: tab.url, selected: true});
return;
}
}
chrome.tabs.create({url: getUrl()});
}
);

It's a function that needs to open an URL defined by getUrl(), but
first looks if it's open already in a tab and reuses the tab if it's
true.

------------------

chrome.tabs.onUpdated.addListener(OnLoginHandler);

function OnLoginHandler (tabId, changeInfo, tab){ // Forces update on
login
if (changeInfo.url && changeInfo.url == loggedInURL){
// ..some code..
}
}

This one checks if any updated tab changed URL to login confirmation
page, and does some work immediately after that.

------------------

Hope it helps.

It does help, I got my test example to work from your first example.
Very clever. Thank you!!

Believe it or not I think I do understand. getAllInWindow gets a
collection of tabs. You're looping over the tabs collection and
evaluating each url value. (I see in the documentation the tab object
has other properties as well.) isURL() and getURL() are your own
custom functions. isUR() L I presume evaluates the current tabs URL in
some manner.

So if I am understanding this correctly, your code is refreshing the
page to itself if it's the correct URL... is that right?
