Iframe parent url

How do I get an Iframe's parent window url using jQuery or Jav开发者_如何学PythonaScript?

Just include the url when opening the iframe.

<iframe 
src="http://foo.bar/iframe.html?iframeparentwindowurl=http://cheese.tv/parrot.html">
</iframe>

For script running in the iframe, use parent.location.href, although an iframe served from a different domain to its parent page will not be able to access this.

If you are on separate domains, there are a few alternative techniques that should work for you. In particular, using the window.name to pass data, or stacking iframes within iframes. Both, and more, are listed in this slideshow. Window.name is mentioned on slide 31. Especially check out slide 34 and on for the iframe stacking technique, which will enable bidirectional communication between differing origin iframes.
