this script I want to use in html template, but I have not found any suitable script
are there any suggestions from you or would like to share to me?
I’m using SC 9

thank you

Here is some JavaScript I use that works for me:


<script type="text/javascript">

/* Disable Right Click - Start */

var isNS = (navigator.appName == "Netscape") ? 1 : 0;

if(navigator.appName == "Netscape") document.captureEvents(Event.MOUSEDOWN||Event.MOUSEUP);

function mischandler(){
return false;
}

function mousehandler(e){
var myevent = (isNS) ? e : event;
var eventbutton = (isNS) ? myevent.which : myevent.button;
if((eventbutton==2)||(eventbutton==3)) return false;
}
document.oncontextmenu = mischandler;
document.onmousedown = mousehandler;
document.onmouseup = mousehandler;

/* Disable Right Click - Stop */
