How to get WHOLE content of iframe?
Question
I need to get whole content of iframe from the same domain. Whole content means that I want everything starting from <html> (including), not only <body> content. Content is modified after load, so I can't get it once again from server.

I belive I've found the best solution:
var document = iframeObject.contentDocument;
var serializer = new XMLSerializer();
var content = serializer.serializeToString(document);
In content we have full iframe content, including DOCTYPE element, which was missing in previous solutions. And in addition this code is very short and clean.

If it is on the same domain, you can just use
iframe.contentWindow.document.documentElement.innerHTML
to get the content of the iframe, except for the <html> and </html> tag, where
iframe = document.getElementById('iframeid');

$('input.test').click(function(){
$('textarea.test').text($('iframe.test').contents());
});

You can get the literal source of any file on the same domain with Ajax, which does not render the html first-
//
function fetchSource(url, callback){
try{
var O= new XMLHttpRequest;
O.open("GET", url, true);
O.onreadystatechange= function(){
if(O.readyState== 4 && O.status== 200){
callback(O.responseText);
}
};
O.send(null);
}
catch(er){}
return url;
}
function printSourceCode(text){
var el= document.createElement('textarea');
el.cols= '80';
el.rows= '20';
el.value= text;
document.body.appendChild(el);
el.focus();
}
fetchSource(location.href, printSourceCode);
