In this tutorial, we are using jQuery UI’s autocomplete widget, to build a simple AJAX movie search form. The script is going to use TheMovieDatabase.org‘s free API, to provide auto suggestions against a vast database of movie titles. For those of you who might not be familiar with TMDb.org, this is an open, community driven movie database. It is similar to IMDb, which you’ve probably heard about, but also provides a number of useful API’s for developers.
