twitter bootstrap typeahead ajax example

Question

I'm trying to find a working example of the twitter bootstrap typeahead element that will make an ajax call to populate it's dropdown.

I have an existing working jquery autocomplete example which defines the ajax url to and how to process the reply

<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
    var options = { minChars:3, max:20 };
    $("#runnerquery").autocomplete('./index/runnerfilter/format/html',options).result(
            function(event, data, formatted)
                {
                    window.location = "./runner/index/id/"+data[1];
                }
            );
       ..

What do i need change to convert this to the typeahead example?

<script type="text/javascript">
//<![CDATA[
$(document).ready(function() {
    var options = { source:'/index/runnerfilter/format/html', items:5 };
    $("#runnerquery").typeahead(options).result(
            function(event, data, formatted)
                {
                    window.location = "./runner/index/id/"+data[1];
                }
            );
       ..

I'm going to wait for the 'Add remote sources support for typeahead' issue to be resolved.

Edit: typeahead is no longer bundled in Bootstrap 3. Check out:

• Where is the typeahead JavaScript module in Bootstrap 3 RC 1?
• typeahead.js

As of Bootstrap 2.1.0 up to 2.3.2, you can do this:

$('.typeahead').typeahead({
    source: function (query, process) {
        return $.get('/typeahead', { query: query }, function (data) {
            return process(data.options);
        });
    }
});

To consume JSON data like this:

{
    "options": [
        "Option 1",
        "Option 2",
        "Option 3",
        "Option 4",
        "Option 5"
    ]
}

Note that the JSON data must be of the right mime type (application/json) so jQuery recognizes it as JSON.
