Question

Is it possible in html/javascript to return the html code of a page?

I have an html page, and i would like to, by a click on a input[type=button], open the source code of the page.

Answer 1

window.location = "view-source:" + window.location.href;

That should work fine in Firefox and Chrome. It won’t work in Internet Explorer though. Another option is to use the outerHTML property:

var source = document.documentElement.outerHTML;

And that should work fine in most browsers. To get that open in a new window, you could do something like this:

var sourceWindow = window.open();
sourceWindow.document.open('text/plain').write(document.documentElement.outerHTML);
