var stop = 0;
var output = “<a href=”/”>Home</a> :: ” ;
sURL = location.href;
sURL = sURL.slice(8,sURL.length);
chunkStart = sURL.indexOf(“/”);
sURL = sURL.slice(chunkStart+1,sURL.length)
while(!stop){
chunkStart = sURL.indexOf(“/”);
if (chunkStart != -1){
bits[x] = sURL.slice(0,chunkStart)
sURL = sURL.slice(chunkStart+1,sURL.length);
}else{
stop = 1;
}
x++;
}
for(var i in bits){
output += “<a href=””;
for(y=1;y<x-i;y++){
output += “../”;
}
output += bits[i] + “/”>” + bits[i] + “</a> :: “;
