How to solve the problem of permission denied.

you cannot access the DOM in a iframe that is from a different domain than your executing script. this is called cross site scripting — Christian Westman, Dec 07 '12 at 07:30

You can't.

Why? It's a security feature to stop Cross-Site Scripting (XSS) attacks.

For example, you have an iframe that loads www.facebook.com. If this security feature wasn't implemented, you could easily fetch data from that site. From cookies, to what content is on the page.

I didn't look at the JS, but you can't get HTML from an remote page with javascript. Try PHP's cURL.

Try

var frame = document.getElementById('f1');
var doc = frame.contentWindow || frame.contentDocument;
var html = doc.document.body.innerHTML

Source: Frame/IFrame contentDocument Property.
