The following article describes how to use FrontPage 2000 to turn off the right-click functionality in Microsoft Internet Explorer versions 5.0 or a later version. These examples use JavaScript in an attempt to discourage users from saving copyrighted images to their computers.

How to Disable Right-Click Functionality

The following examples illustrate two methods for turning off (disabling) right-click functionality in a browser. 

NOTE: You may receive an error message if you copy and paste the examples directly from this article into FrontPage. The angle brackets (“<” and “>”) may appear as escaped HTML code (“<” and “>”). To work around this behavior, paste the script in a blank Notepad document, and then copy it from Notepad before you paste it into FrontPage.

Example #1: Turn Off the Shortcut Menu

  1. Open a new page in FrontPage.
  2. Switch to HTML view.
  3. Locate the opening <BODY> tag.
  4. Modify the <BODY> tag to resemble the following: 

    <body onContextMenu="return false">

  5. Preview the page in Internet Explorer 5.0 or later. When you attempt to right-click anywhere on the page, the shortcut menu is not displayed.

Example #2: Use JavaScript to Display a Warning Message

  1. Open a new page in FrontPage.
  2. On the Insert menu, click Advanced.
  3. Select HTML.
  4. Type the following JavaScript code into the HTML Markup box: 

    <script language="JavaScript">

var message = "Sorry, that function is disabled.\n\n";
message += "This page is copyrighted, and ";
message += "all content is protected."; 

function click(e) {
  if (document.all) {
    if (event.button == 2) {
      alert(message);
      return false;
    }
  }
  if (document.layers) {
    if (e.which == 3) {
      alert(message);
      return false;
    }
  }
}

if (document.layers) {
  document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
</script>

  5. Click OK.
  6. Preview the page in Internet Explorer 5.0 or later. When you attempt to right-click anywhere on the page, a message box appears, stating that the contents of the page are copyrighted, and therefore the right-click function is turned off (disabled).

Additional Information

Microsoft Internet Explorer allows users to save Web pages and all embedded images to their computer’s hard disk. The implementation of this article will not protect images or source code from being copied, but it will serve as a method for possibly deterring some Web users.
