A number of people have asked me over the past few days how should one go about using jQuery Autocomplete but instead of using newline delimiters, with a URL that returns JSON data.
At first, I first had a hack that involved handling the “keyup” event myself then sending a request to a JSON URL, and then involve the “autocompleteArray” method from Autocomplete. It was a mess considering that the autocomplete method is already sending the value of your defined input to the server as a GET parameter. I was repeating the behavior of the function in order to receive a simple JSON array. I was unhappy, and felt it to be a very annoying solution because I wanted to take advantage of the internal caching system of jQuery Autocomplete.
So I decided to give a look at the code and came up with a much cleaner solution. I directly added a JSON option to the Autocomplete. So for anyone interested you can find the patch here: jQuery Autocomplete JSON patch.
