Twitter's Bootstrap typeahead setup

valk picture valk · May 1, 2013 · Viewed 7.9k times · Source

I'm using the official examples from Twitter. The main problem, I probably don't know how to use the Hogan monster. The JS side:

$("#search_name").typeahead({
    name: 'name',
    remote: {
        url: '/entities/search_autocomplete.json?query=%QUERY',
        template: '<p><strong>{{id}}</strong> – {{name}}</p>',
        engine: Hogan
      }
});

The server is returning the data in JSON, the structure is:

[{\"id\":1234,\"name\":\"Blah blah...\",\"tokens\":[\"blah...\",\"blah\"]}]

Just took this code from one of our projects, should help you understand the necessary markup of converting external JSON arrays and outputting in a custom autocomplete prompt:

$('input').typeahead({
    header: 'Your Events',
    template: [
    '<img class="ta-thumb" src="https://graph.facebook.com/{{id}}/picture?type=square" />',
    '<p class="ta-h1">{{name}}</p>',
    '<p class="ta-p">{{start_time}}</p>'
    ].join(''),
    limit: 3,
    remote: {
        url: 'https://graph.facebook.com/me/events?access_token=' + access_token,
        filter: function(parsedResponse) {
            var dataset = [];
            for(i = 0; i < parsedResponse.data.length; i++) {
                dataset.push({
                    name: parsedResponse.data[i].name,
                    start_time: parsedResponse.data[i].start_time,
                    id: parsedResponse.data[i].id,
                    value: parsedResponse.data[i].name,
                    tokens: [parsedResponse.data[i].id, parsedResponse.data[i].name]
                });
            }
            return dataset;
        },
    },
    engine: Hogan
});

You need to download the Hogan.js template compiler and include it in your markup (e.g. using it as an external script or via a module loader like Require.js). This will then set the Hogan variable.

I'd also recommend looking at that Graph API call to understand the array conversion better.

Hopefully this helps :)
