Twitter Bootstrap Typeahead – Id & Label

There’s a great tutorial here that explains how to do this: http://tatiyants.com/how-to-use-json-objects-with-twitter-bootstrap-typeahead/ (read my comment on that page if it hasn’t been reflected yet in the main part of the post).

Based on that tutorial, and the JSON you provided, you can do something like this:

$(':input.autocomplete').typeahead({
    source: function(query, process) {
        objects = [];
        map = {};
        var data = [{"id":1,"label":"machin"},{"id":2,"label":"truc"}] // Or get your JSON dynamically and load it into this variable
        $.each(data, function(i, object) {
            map[object.label] = object;
            objects.push(object.label);
        });
        process(objects);
    },
    updater: function(item) {
        $('hiddenInputElement').val(map[item].id);
        return item;
    }
});
