Get a Javascript variable outside the script

[patrick]

<script>
  var vuFp = new VUBrowserFP();

  vuFp.getFingerprintInfo(function(info) {
    dmx.global.set('bfp', info.fingerprint);
  });

  vuFp.getFingerprintInfoWithSeed(function(info) {
    dmx.global.set('bfpSeed', info.fingerprint);
  });
</script>

access it directly with {{ bfp }} and {{ bfpSeed }}.
