problem with chrome.tabs.executeScript

[Oleg Sokolov]

Chrome sees this code, but doesn't execute the script. Although if I
put a line "window.close();" - it works. But with
"chrome.tabs.executeScript" it doesn;t.

chrome.tabs.executeScript(null, {code: "window.close();"});

What can be the reason?
Please, don't advise me to use simply "window.close()". My problem is
more complicated, with tabId instead of null, so I need this chrome
method.
I just changed tabId to null to find out if the problem was in tabId.

Can you be a bit clearer about what you're trying to do, how your extension is structured, and what exactly "works" or doesn't?  

What do you mean by "Chrome sees this code"?

You say window.close works but chrome.tabs.executeScript doesn't.  But this line has both: chrome.tabs.executeScript(null, {code: "window.close();"}); - so what happens there?

What part of your extension is calling chrome.tabs.executeScript?

Can you use chrome.tabs.remove(tabId)?

Otherwise, do you have host permissions? If not, you should see errors
in your extension's page's developer tools console. "To insert code
into a page, your extension must have cross-origin permissions for the
page. It also must be able to use the chrome.tabs module."

OK, I'll describe the situation in details.

My extension overrides chrome://newtab/ with specific page. Imagine
that some amount of them is opened in different tabs.
I have got an array with all these tabs' IDs.

Then, something happens on one page and I need to update the
information on some of the rest.
First, I used chrome.tabs.update(tabId, ...) and all was going right.
But now I don't want to reload pages, but to update one element on
them.
So I wrote:

chrome.tabs.executeScript(parseInt(tabId), {code:
"document.getElementById('box' + " + slot + ").innerHTML =
boxContent(" + thumbId + ");"});

And it doesn't work. Yes, I suppose that the problem is in
permissions, but what should I do to solve it?
In manifest I have "permissions": [ "tabs", ..., "*://*/*"]
If I want to insert code into a page that I created myself earlier,
there should be a way to do it!

You can't call executeScript on chrome-extension:// pages, even if the page is in your own extension.

You should call chrome.extension.getViews to get a list of all the windows open in your application instead:

http://code.google.com/chrome/extensions/extension.html#method-getViews

var wins = chrome.extension.getViews({type:'tab'});

for (var i = 0, win; win = wins[i]; i++) {

  win.document.getElementById .... // etc

}

Thanks a lot! This was exactly what I needed.
