Disable Right Click using Javascript

A few days back I while checking out some of the sites I stumbled upon a nicely designed site. I liked its css and so to check it out I right clicked to view source, but to my surprise it showed up an alert box saying :

” Sorry, right-click has been disabled “

Anyhow there are still more ways to find the source code, so finally I digged out this small java script code in the head section which did all the magic.

Code:

[javascript] <script language=”Javascript”>

function mycontextmenu() {

alert(‘Sorry, right-click has been disabled’);

return false;

}

document.oncontextmenu = mycontextmenu();

</script> [/javascript]
