Can I call the blockchain.info API with just javascript or jQuery?

I'm trying to load http://blockchain.info/unspent?active=$address. From what i've read it should be possible somehow with cors, but i've been checking urls with this cors test: http://client.cors-api.appspot.com/client, and with or without the "?cors=true" i'm not having much luck.

Has anyone got this to work?
