I have a sharepoint hosted app page.
I have a link in it. Clicking on it it should open a modal pop up whose url is the home page of the sharepoint site.
I am able to open a modal pop up window but it is not showing any content of any external site. I tried the url as "http://www.google.com/", still the modal pop up window was blank. I have used the code :
Any idea why the content of the modal is null or displaying null?
