Here is two javascript code, helps you to disable right click, on webpages with Javascript.
function NoRightClick() {
if (event.button == 2)
{
alert("This action is not possible")
}
}
document.onmousedown=NoRightClick;
Or you can simply use.
<body oncontextmenu="return(false);">
This second code works only in Microsoft Internet Explorer.
