jQuery plugin for autocompletion of hometown

I am wondering if there is a readymade jquery/ajax/javascript开发者_高级运维 plugin that hooks into an API of somesorts that provides a similar result to facebook hometown autocompletion in the profile?

Take a look at JqueryUI Autocomplete

Here is a good example with cities completion, reusing third party cities API
