Hi. This question isn't about popping up an iframe inside a Lightbox; rather, it's about an iframe on a page that can launch its own Lightbox-style box in the page that contains that iframe. I'm thinking this can't be possible, because the iframe contains the contents of the other URL and whatever Lightbox that URL launches has to fit within the iframe. Thanks.
If both sites belong to the same domain you can add the JS of the lightbox to the main frame and call the function inside the iframe using ´parent.function´
It is not possible for the <iframe>
to interact with its parent frame if the two frames are on different domains.
Try looking at fancybox. I know that supports iframes, and I always use it over Lightbox, much more customisable. I am pretty sure it can deal with nested iframes, however I could be wrong. Worth a try nether the less.
Can display images, HTML elements, SWF movies, Iframes and also Ajax requests
There are examples on the bottom of the page: http://fancybox.net/
I don't know if it's around anywhere online, but i saw Facebook give a presentation about injecting an iframe into other sites to circumvent such problems with cross-site issues. Worth a look.
