[Irc|RFC 1459] In Javascript

[fvuj]

Schonmal was vom NOT-Operator gehört?

http://www.w3schools.com/js/js_comparisons.asp

function pong(servermessage) { 
    if(servermessage.indexOf("PING :")!=-1)
         cl_msg = servermessage.replace("PING","PONG"); 
         return cl_ms;
    }
}

Sollte doch so funktionieren?
