You are trying to access content of iframe which points to webpage from another domain. You cannot access content of iframe if the src of that iframe is not pointing to the domain on which your current parent page is. This is called cross domain policy
You will have to use server side language that will grab the html of given url and return it to your index page to display in any div or whatever.
Let me give you an example to explain why javascript cannot have cross domain access.
- Suppose i have FB like box on my website inside an iframe
- now whenever any user comes on my website i will trigger a click to the like box which is inside the iframe of like box.
- This way my FB page will have lakhs of likes.
- But because of cross domain policy this cannot be done.
