I searched around and still have not a clear plan yet.
I made a RSS reader app based on the appery tutorial. Now I made a page and allow users to change this pre-set rss feed source to their own favorite rss feed. So, I put a input object to the page and allow the users to input an alternative URL.
that I called an javascrip is the page button click event:
RSSserviceName.__requestOptions.url = "http://www.osha.gov/pls/oshaweb/newsR...";
But when I navigate back, the rss feed page becomes blank. I checked the code and the error I got says "XMLHttpRequest cannot load http://search.espn.go.com/rss/feed/. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://appery.io' is therefore not allowed access."
Please help, I already tested in both device and web.
