javascript breadcrumbs displays subfolders as links

[sj_polanco]

I want to include location based breadcrumbs on my site. i searched for free javascripts that i could use. i found this one:

/* This script and many more are available free online at
The JavaScript Source!!

function breadcrumbs() {
  sURL = new String;
  bits = new Object;
  var x = 0;
  var stop = 0;
  var output = "<div id=breadcrumbs>You are here:\ <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> » ";
  }
  document.write(output + document.title);
  document.write("</div>");
  }

My only reservation with the code is that it displays my sub folders as links. How can i prevent subfolders from displaying as links?
