Doesn't seem to be any value in using a lambda here, just do:
$('export').onclick = exportCertificate;

[flackr, 2011/08/09 18:25:15]

Done.

can you just send an empty array for the args instead of an array with an empty
string?

[flackr, 2011/08/09 18:25:15]

Done.

I'd suggest just using Array.push instead of Array.concat (no need to make
another copy).
