Answer 2

iframe content has its own separate document. To get to it, you need to get the iframe and access its contentDocument.
Here is a very simplified code:

var iframe = document.getElementsByTagName('iframe')[0];
var insideDoc = iframe.contentDocument;
var insideDocTestElem = insideDoc.getElementById('test');

InsideDoc stores the document, but not your page, but the contents of the frame. It is important to note right away that the browser prevents access to iframe content in certain cases, so the connection protocol, domain, and so on are important.
