How can a content script determine if it is in a frame (iframe) or
not?

Any method is ok.

You can check by using this script:

if(window.parent){

//it is

}else{

/it is not

}

Yes, I wrote the code wrong. It actually is:

if(!window.parent){ //it is }else{ //it is not }

No it doesn't work...

Anyway, i already find a solution:
if(self==top){
// in a frame
}

Thanks anyway

what is the reason that window.parent returns undefined in content
scripts when asked on frames, while when asked in regular web page it
works?
(chrome 8.0.552.237)

There are known issues with accessing the global "window" object of other frames (be it a parent frame, or an iFrame, or a frame within a frame set) from content scripts.

You can search crbug.com for it and star it. There is already an issue filed for it, so do not file a new one, nor add comments to the existing one.

If you had no luck with top !== self, try if (typeof window.frameElement !== 'undefined') instead. Chances are that will work better (whether you can actually access the frame element of the parent window or not).

Any method is ok.

Good luck!
