Javascript is not like a server-side language. The browser runs the JS. Server-side languages run the code and then output regular markup (or JS).

Javascript is executed on the client-side. Since the browser can decipher the JS on its own, it doesn't need to rewrite it as HTML. All that will do is slow up the page loading time. I don't know of any programs that will do that either. What you will need to do it go through the Javascript and see what it outputs...

Netscape 4 shows the result of document.write when you view source, rather than the JavaScript itself. This will mean that you can see the JavaScript-generated markup, if any.

Although now a legacy browser, Netscape 4 is still available from the following URL :

Hooo boy, netscape 4...

You know, there is something in any modern browser that is called DOM explorer.
This is what you are looking for.
Typically, google use javascript to create an iframe in your page.

As it's not coming from the source file, you swon't see nothing with "view source", but with the dom explorer, you can see what is the state of the Document Object Model and every elements contained into it at any time.

In firefox, you must install FF and select "custom install" to get it.
But the easier solution, is to install firebug, and on the page you want to examine:
1:
open the firebug console with f12
2:
click the "examine" button
3:
Hover your mouse over what you want to look for, and click on it.The browser won't follow any links, but you will get the normal focus back
Once there, you can see the DOM source in the firebug console, and even modify it (change css value, add new attributes...)
