Re: Content script can't get selection from iframe (was:Best way to get selected text from google doc page(iframe?))

[arthur zhang]

After two days testing, looks content script can't get iframe's
selection at all (e.g. edit area of google doc).

I have "all_frames": true, in manifest.json to make sure the content
script is running with iframe, and add event handler to both mousedown
and mouseup events. After using mouse to select something in the
iframe, both of the events got fired but in mouseup handler,
windows.getselection() returns nothing and e.target.contentWindow is
not accessible.

Can anyone confirm that content script can't get selection from iframe.

Thanks.
