Both blockchain.info and blockr.io have APIs you can use for this purpose. You can load https://blockchain.info/address/{ADDRESS HERE}?format=json or http://btc.blockr.io/api/v1/address/info/{ADDRESS HERE} using AJAX and parse the JSON.
I have recently become active again after a long period of inactivity. Cryptographic proof that my account has not been compromised is available.

Ajax doesn't allow you to make requests to another domain. So if your site is on example.com, your javascript can't query an external URL like btc.blockr.io.
In theory, there's no difference between theory and practice. In practice, there is.

What?? Huh Huh
Today, cross domain Ajax request is supported for major browsers.
You can use several resources for a request cross domain , for example: JSONP, OpenAjax Hub, easyXDM, etc, also proxified petitions can help, or simply type in google CORS, cross domain, etc etc.
