Getting Contents of Iframe with Pure JavaScript
Solution 1:
If it is on the same domain, try this. It won't let you access iframe contents if the iframe is of a different origin than the window that you are viewing.
var iframe = document.getElementById("awc_frame");
var iframe_contents = iframe.contentDocument.body.innerHTML;
