function chk ()
{
var val = document.f.name.value;
var wert = val.length;
var wertt = wert-1;
var last = val.substring(wertt,wert);
sz = new Array("ö","ä","ü","Ö","Ä","Ü","_"," ","!","§","$","%","&","/","(",")","=","ß","?","","*","~","+","²","³","'","#");
var szl = sz.length;
for (var i=0; i <= szl; i++)
{
if (last == sz[i])
{
valb = val.substring(0,wertt);
document.f.name.value = valb;
alert("Sie sollen doch keine " + last + "´s oder ander Sonderzeichen verwenden!");
}
}
}
