Answer 1

The location object is not a string, array, or any other object which has an indexOf method. Perhaps you meant to use opener.location.href.indexOf(...)?

Answer 2

The problem is that location is not a String, it is a Location object. You can use toString method of location to convert it to string:

window.opener.location.toString().indexOf(document.location.hostname)
