jquery - Why does bloodhound.get() return undefined? -

i'm trying use code below typeahead.js v 0.10

// instantiate bloodhound suggestion engine var numbers = new bloodhound({ datumtokenizer: function(d) { return d; }, querytokenizer: bloodhound.tokenizers.whitespace, local:  ["(a)labama","alaska","arizona","arkansas"] });  // initialize bloodhound suggestion engine numbers.initialize(); console.log(numbers.get('a')); 

in fact try solve question: https://github.com/bassjobsen/bootstrap-3-typeahead/issues/26 expected shown below should possible:

 $('.typeahead').typeahead( { items: 4, source:function(query){return numbers.get(query)}        }); 

update

the examples. use ttadapter() set source of typeahead. function can used set source property (which accept array of string or function) bootstrap-3-typeahead:

// instantiate bloodhound suggestion engine var numbers = new bloodhound({ datumtokenizer: bloodhound.tokenizers.whitespace,//function(d) { return d; }, querytokenizer: bloodhound.tokenizers.whitespace, local:  ["(a)labama","alaska","arizona","arkansas","arkansas2","barkansas"] });  // initialize bloodhound suggestion engine numbers.initialize();  $('.typeahead').typeahead( { items: 4, source:numbers.ttadapter()   }); 

bloodhound.js shows:

  ttadapter: function ttadapter() {                 return _.bind(this.get, this);             } 

so ttadapter() returns function (get()) can set source has query argument.

i implemented bloodhound.get() follows (also see fiddle : http://jsfiddle.net/fresh/hs9wy/):

// instantiate bloodhound suggestion engine var numbers = new bloodhound({     datumtokenizer: function (d) {         return d;     },     querytokenizer: bloodhound.tokenizers.whitespace,     local: ["(a)labama", "alaska", "arizona", "arkansas"] });  // initialize bloodhound suggestion engine numbers.initialize();  // array of datums satisfy query 'a' numbers.get('a', function (suggestions) {     jquery.each(suggestions, function (index, item) {         console.log(item);     }); }); 

the problem call "get()" i.e.

numbers.get('a') 

is whilst getting bloodhound execute query 'a' not doing results. instruct "get()" useful need send results output function. see documentation here.
