I just created an iFrame with the sandbox
attribute. Whenever I try to open a link with target="_blank"
or target="_top"
or when I try to use window.open()
nothing happens.
Here's my code:
<iframe src="http://www.google.com/"
sandbox="allow-top-navigation allow-same-origin allow-forms allow-scripts">
Apparently your browser doesn't support iFrames!
</iframe>
Apparently Chrome allows an undocumented sandbox property called allow-popups
to be set. The property is also supported in Firefox and is a Candidate Recommendation on W3C .
allow-popups
lets the sandboxed frame open links in new windows or tabs and, it appears, when the frame tries to open a link with target="_top"
the browser will open the URL in a new tab or window.
