Menu
I'm trying to add a link or button to my site where the user can see the source of the current page.
No luck when tried the following:
<a href="view-source:http://www.example.com" target="_blank">View Source</a>
Any other idea? Maybe with javascript we can get the source from the current page?
Thank you

You can add a simple button as follows:
<button type ="button" onclick="viewSource()">View Source</button>
And then the following javascript function:
function viewSource(){;
var source = "<html>";
source += document.getElementsByTagName('html')[0].innerHTML;
source += "</html>";
source = source.replace(/</g, "<").replace(/>/g, ">");
source = "<pre>"+source+"</pre>";
sourceWindow = window.open('','Source of page','height=800,width=800,scrollbars=1,resizable=1');
sourceWindow.document.write(source);
sourceWindow.document.close();
if(window.focus) sourceWindow.focus();
}
This will open it's own window and display the source of the current page.

Check this link
Here there is a nice example of creating View Source button
Html:
<a href="#source-code">View Source</a>
<div id="#source-code"></div>
Css:
#source-code { display: none; }
#source-code:target { display: block; }
Javascript:
var html = $("html").html();
$(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>'
}).appendTo("#source-code");
});
