Find out weather a tab has rendered content or not

(Fdsfdsf) #1

I looked at

I use

  • but the returned value is status:undefined and index: NaN

however the id is correct, as
closes the tab in question.

What I intend to find out is, weather the tab with tabId has rendered content. This is slightly different from determining the status or URL i think, because when a tab is redirected there is an URL but no rendered content)
