Bootstrap 3 typeahead.js - query by part of typeahead val

I'm trying to call my remote url with last part of input value. I would like to do something like this:

    $('#typeahead').typeahead({
    remote: {
        url: '/ajax/tags/get/?name=%QUERY',
        replace: function (url, query) {
            var last = query.split(',');
            last = $.trim(last[last.length-1]);
            return url.replace('%QUERY', last);
        }
    },
    limit : 10
});

and when dropdown item selected,

For Bootstrap 3 you can use Bootstrap-3-Typeahead.

You will have to overwrite the updater and matcher functions. For the matcher function you can use the code from your replace function as follows:

matcher: function (item) {
        var last = this.query.split(',');
        this.query = $.trim(last[last.length-1]);

        if(this.query.length) return ~item.toLowerCase().indexOf(this.query.toLowerCase());
}

Use the following code for your update:

updater: function (item) {
      return this.$element.val().replace(new RegExp(this.query + '$'),'') + item + ',';
    }

(match last occurrence from: JavaScript: replace last occurrence of text in a string )

Complete example:

$('.typeahead').typeahead (
{
items: 4,
source: function (query, process) {
    states = [];
    map = {};


    var data = [
        {"stateCode": "CA", "stateName": "California"},
        {"stateCode": "AZ", "stateName": "Arizona"},
        {"stateCode": "NY", "stateName": "New York"},
        {"stateCode": "NV", "stateName": "Nevada"},
        {"stateCode": "OH", "stateName": "Ohio"}
    ];

    $.each(data, function (i, state) {
        map[state.stateName] = state;
        states.push(state.stateName);
    });

    process(states);

}

  , updater: function (item) {
      return this.$element.val().replace(new RegExp(this.query + '$'),'') + item + ',';
    }
    , matcher: function (item) {
        var last = this.query.split(',');
        this.query = $.trim(last[last.length-1]);

        if(this.query.length) return ~item.toLowerCase().indexOf(this.query.toLowerCase());
    }
    }

);

Assuming that "query with the last part" works for you, you can use filter: function(response) {...} to populate and return an array of datums that have appropriate value and title to do what you want.
