bloodhound.js

// constructs the suggestion engine
var engine = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  // `states` is an array of state names defined in "The Basics"
  local: $.map(states, function(state) { return { value: state }; })
});

// kicks off the loading/processing of `local` and `prefetch`
engine.initialize();

$('#bloodhound .typeahead').typeahead({
  hint: true,
  highlight: true,
  minLength: 1
},
{
  name: 'states',
  displayKey: 'value',
  // `ttAdapter` wraps the suggestion engine in an adapter that
  // is compatible with the typeahead jQuery plugin
  source: engine.ttAdapter()
});

Can you give a link to the json this code is referencing?

I am assuming the states array will be like as :

var states = [ "Ohio", "New York", "Florida"];
