I know it looks complicated but I am giving you a 100% bullet proof way that works to view your source codes on your page.
I do not exactly know how to show it in iframes, but there is another way to view source codes witch is much better then iframes and this is how.
What is important is the JavaScript and the HTML is exactly like this.
CSS: In the <head></head>
section:
<style type="text/css" >
.button
{
background:#000cff;
padding:2px 10px;
color:white;
text-decoration:none;
-moz-border-radius:10px;
-webkit-border-radius:10px;
border-radius:10px;
cursor: pointer;
font-weight: bold;
color: white;
display: inline-block;
box-shadow: 0 0 3px gray;
margin: 0px;
font: bold 11px Arial, Sans-Serif;
}
#source-code
{
display:none;
position:absolute;
top:-24px;
left:0;
width:100%;
height:414px;
background:rgba(255,255,255,0.0);
}
#source-code:target { display: block; }
#source-code pre
{
padding:20px;
font:14px/1.6 Monaco, Courier, MonoSpace;
margin:50px auto;
background:rgba(0,0,0,0.8);
color:white;
width:80%;
height:80%;
overflow:auto;
}
#source-code pre a,
#source-code pre a span
{
text-decoration:none;
color:#00ccff !important;
}
#x
{
position:absolute;
top:30px;
left:10%;
margin-left:-41px;
}
.control-copytextarea
{
position:absolute;
top:-3px;
left:20px;
cursor: pointer;
font-weight: bold;
padding:3px 10px;
border-radius: 5px 5px 0 0;
background: darkred;
color: white;
display: inline-block;
box-shadow: 0 0 3px gray;
margin: 0px;
font: bold 10px Arial, Sans-Serif;
}
</style>
JavaScript:
<script languade="JavaScript">
$(function() {
$("<pre />", {
"html": '<!DOCTYPE html>n<html>n' +
$("html")
.html()
.replace(/[<>]/g, function(m) { return {'<':'<','>':'>'}[m]})
.replace(/((ftp|http|https)://(w+:{0,1}w*@)?(S+)(:[0-9]+)?(/|/([w#!:.?+=&%@!-/]))?)/gi,'<a href="$1">$1</a>') +
'n</html>',
"class": "prettyprint"
}).appendTo("#source-code");
prettyPrint();
});
</script>
<script languade="JavaScript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script languade="JavaScript">
var pageTracker = _gat._getTracker("UA-68528-29");
pageTracker._initData();
pageTracker._trackPageview();
</script>
NOTE:
You do not need to use these JavaScript codes from online, but for the sake of having it work on all browsers it is advised you use them too.

The <iframe> tag specifies an inline frame. It allows us to load a separate HTML file into an existing document.
Code snippet:
function getIframeContent(frameId) { var frameObj = document.getElementById(frameId); var frameContent = frameObj. contentWindow.document.body.innerHTML; alert("frame content : " + frameContent); }
Some of the definitions are given below:
- getIframeContent(frameId): It is used to get the object reference of an iframe.
- contentWindow: It is a property which returns the window object of the iframe.
- contentWindow.document: It returns the document object of iframe window.
- contentWindow.document.body.innerHTML: It returns the HTML content of iframe body.
Example: The following example demonstrates to include separate HTML file into existing document.
<!DOCTYPE html>

Добрый день!
У меня есть iframe
В него загружается страница site.com/index.htm
Каким образом я могу просмотреть исходник этой страницы?
Если с iframe так нельзя, подскажите, как это же самое сделать с окном ( window.open()
)

Откройте панель инструментов F12 или CTRL+SHIFT+I
Каким образом я могу просмотреть исходник этой страницы?
Конечная цель какая? Получить доступ к DOM через JS?
window.frames[0].document.body.innerHTML
Правой клавишей щелкнуть по фрейму, в контекстном меню выбрать “В этом фрейме > Исходный код фрейма”. В разных браузерах формулировки могут отличаться, но суть та же.

I have a webpage where there is a textarea within a iframe. I need to read the value of this textarea from its child page JavaScript. Presently by using window.parent.getelementbyID().value
in the JavaScript, I am able to fetch values of all controls in the parent page except the textarea within the iframe.
The frame id and frame name in my parent page changes in runtime, hence we cannot use the frame id/frame name for reference.

If you have the HTML
<form name="formname" .... id="form-first">
<iframe id="one" src="iframe2.html">
</iframe>
</form>
and JavaScript
function iframeRef( frameRef ) {
return frameRef.contentWindow
? frameRef.contentWindow.document
: frameRef.contentDocument
}
var inside = iframeRef( document.getElementById('one') )
inside
is now a reference to the document, so you can do getElementsByTagName('textarea')
and whatever you like, depending on what’s inside the iframe src.

Using jQuery you can use contents()
. For example:
var inside = $('#one').contents();

Я знаю, что это выглядит сложным, но я даю вам 100% пуленепробиваемый способ просмотра исходных кодов на вашей странице.
Я точно не знаю, как показать это в iframe, но есть другой способ просмотра исходных кодов, который намного лучше, чем iframe, и вот как.
Важен JavaScript, и HTML в точности такой.
