How to force link from iframe to be opened in the parent window
I found the best solution was to use the base tag. Add the following to the head of the page in the iframe:
<base target="_parent">
This will load all links on the page in the parent window. If you want your links to load in a new window, use:
<base target="_blank">
Browser Support
Use target-attribute:
<a target="_parent" href="http://url.org">link</a>
