If I have a modal pop up using the pattern in mockup, links within the current domain work fine. But sometimes I would like to have it go to some external resource. When I try to do this I get blocked by the browser which seems to be an attempt to prevent cross site scripting:
XMLHttpRequest cannot load https://www.google.com/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'null' is therefore not allowed access.
Is there some data value I can pass to make this work or is it unsupported?
