Programmatically open “View Source” HTML Window in Browser with Javascript?
You can use the “view-source” URI schema, supported by Firefox, Chrome, and older versions of IE. No JavaScript required, just a normal link to the page you want the user to see in source view: <a target=”_blank” href=”view-source:http://www.wikipedia.org/”>view Wikipedia’s home page HTML source</a> More info: http://en.wikipedia.org/wiki/View-source
