Approaching Typeahead.js prefatched datums

Question

I'm using Twitter Typeahead.js like this:

$('.autocomplete').typeahead({
  name: 'autocomplete',
  prefetch: https://localhost/datums.json
});

Is there any possibility how to approach datums.json values anywhere else in the script? Like creating a condition asking if some value exists in typeahead's datums.

Answer 1

If I understand what you are asking for, you can use local instead of prefetch. Use an HTTP client (XMLHttpRequest, e.g.) to read /datums.json yourself, and store a reference to it in a variable. Then pass that variable as local to Typeahead.
