About Anti-Right-Click Protection
Disabling the browser’s context menu is a classic method to prevent the theft of web page content. With the help of JavaScript, it’s quite easy to block right-clicks by cancelling “oncontextmenu” events (see the code below). Although there are many ways to bypass this kind of protection, and although the solution doesn’t work in all browsers, implementing the solution is often better than doing nothing to prevent content theft.
The Script
To disable right-clicking on your web page, simply copy and paste the following code to the <head> (or <body>) section of your pages’ HTML code:
<script language="JavaScript" type="text/javascript"> <!-- // Setting "onlyOnImages" to "true" will disable right-clicking only for // images var onlyOnImages = false; // Detect the browser var isIE5 = document.all && document.getElementById; // IE 5 or higher var isMoz = !isIE5 && document.getElementById; // Mozilla/Firefox function cancelContextMenu(e) { // Here you can add additional code that is executed when the context menu // is blocked. For instance, you can use the following code to display a // message to the user: // alert("Right-click disabled!"); return false; } /* This function is fired every time a user clicks the right mouse button to open the browser's context menu. */ function onContextMenu(e) { // Depending on the "onlyOnImages" variable the context menu is either // blocked for the complete page or only for <img> tags. if (!onlyOnImages || (isIE5 && event.srcElement.tagName == "IMG") || (IsMoz && e.target.tagName == "IMG")) { return cancelContextMenu(e); } } if (document.getElementById) { // Register event handler document.oncontextmenu = onContextMenu; } --> </script>
The script allows you to choose whether or not to disable right-clicks only on images (onlyOnImages = true) or for the complete page (onlyOnImages = true).
