chrome.tabs.executeScript to get returned value from javascript code or file

[jwvai316]

Hi,

on chrome.tabs.executeScript(integer tabId, object details,
function callback)

Can the javascript code or file on the object details return value?

if it can, then how do I get the value returned by the javascript code
or file inside object details
and use the value in the callback function?

Thanks.

It sounds like you want the code you execute using chrome.tabs.executeScript to send a message back to the background page.  If this is correct, you can do this using message passing - set up a listener in the background page and call chrome.extension.sendRequest from your code snippet.  See http://code.google.com/chrome/extensions/messaging.html for more detailed information about how this works.

Cheers,

Thanks Arne,

I know understand that the message passing does not work as call and
return to the caller. It is more like send the request (in this case
the value to be returned) and add listener to get the request. thus,
allowing other page to get the value too..

Thanks.
