Example of Disabling "View Source"

(Works with IE & Netscape)

In the below URL's I have placed a HTML comment in the source that states my favorite baseball team.  See if you can view the source.  For the average web user this will be difficult.  For the hacker, as some of you have pointed out, it will be easy.

Hacker comments:

• On a 104 key keyboard, if you press the "Context Menu" button you can view the source.
• Doesn't work with some browsers.  Browsers other than IE & NS may not support the trapping of keystrokes.

The source code for all of the JavaScript examples of working with the window object is located at Window Object

Examples  (IE & NS)

• Click Here - to have JavaScript load another HTML file in a new browser window that also disables the "View Source" option via the Toolbars or Right Click.
  • Note:  If you were a hacker, you could open up the cached page or .js file and view the source.  To find the directory of cached files for IE on a WinNT machine do the following.  Tools, Internet Options, Temporary Internet Files, Settings, View Files.  You will find cached pages and cookies here.  If you have trouble trying to directly edit in this directory, copy the file to another location and edit.  (ex location: C:\WINNT\Profiles\<your user id>\Temporary Internet Files )
• Click Here - to have JavaScript disable caching (if the browser does so) and the same as above.

Warning - The below link will hang your browser.
!!! Test on Local Machine using IE !!!!

Works on Local PC, but not at my web site - very confusing to me!.  If run from my web site your browser will  hang.  I am leaving this code at my web site in hopes that I'll fix the problem later or that someone will fix the code and email it to me.

For the JavaScript guru's: 

•  It look like you cannot create a script tag that loads a .js file using the document.writeln() function.
  Ex that fails: winNew.document.writeln("<script language=\"JavaScript\" src=\"ex_window_norightclick.js\"> </script>");

• Testing results:

  • On Local PC using IE 5.5 - Works fine.

  • At web site using IE 5.5 - Browser hangs.

  • On Local PC using Netscape 4.7 - The .js entry in the source code does not get created even though the JavaScript should be creating the entry.  Does not work.

  • At web site using Netscape 4.7 - Works fine.  In addition, Netscape will ask the user to "Grant" privileges for "modifying the browser" before this current page is loaded.  I don't understand why it asks for those privileges on this web page.

Here is the link.

• Click Here - to have JavaScript build a new browser window with HTML content that disables the "View Source" option via the Toolbars or Right Click.
