Datejs is a bit bloated if you only need to do this. You can use split() and concatenate the results:

var eu_date = '30.01.2010';
var parts = eu_date.split('.');
var us_date = parts[2]+'-'+parts[1]+'-'+parts[0];

For these kinds of conversions where no date logic is needed, it's usually smartest to just use string manipulation tools.
