Ridiculously simple live currency conversion. I will make it into a jquery plugin soon but for now, if you put the convert.js snippet inside a jquery document ready tag it should just work™.
if $('span[data-currency]').length > 0
$.get '//query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.xchange%20where%20pair%20in%20(%22EURUSD%22%2C%20%22EURGBP%22%2C%20%22EURJPY%22)&format=json&diagnostics=true&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys&callback=', (result) ->
$('span[data-currency]').each ->
matches = $(this).data('currency').match(/(\d+) (.+)/)
amount = parseInt(matches[1])
conversion = matches[2]
for conversions in result.query.results.rate
if conversion == conversions.Name
rate = conversions.Rate
return $(this).text Math.floor(amount * rate)
