编辑:typeahead不再捆绑在Bootstrap 3中。查看:

在Bootstrap 3 RC 1中输入JavaScript模块在哪里? typeahead.js

从Bootstrap 2.1.0到2.3.2，你可以这样做:

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

像这样使用JSON数据:

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

注意JSON数据必须是正确的mime类型(application/ JSON)，这样jQuery才能将其识别为JSON。

我用ajax功能增强了原始的typeahead Bootstrap插件。非常容易使用:

$("#ajax-typeahead").typeahead({
     ajax: "/path/to/source"
});

这里是github回购:Ajax-Typeahead

如果你的服务没有返回正确的application/json内容类型头，试试这个方法:

$('.typeahead').typeahead({
    source: function (query, process) {
        return $.get('/typeahead', { query: query }, function (data) {
            var json = JSON.parse(data); // string to json
            return process(json.options);
        });
    }
});

我正在用这个方法

$('.typeahead').typeahead({
    hint: true,
    highlight: true,
    minLength: 1
},
    {
    name: 'options',
    displayKey: 'value',
    source: function (query, process) {
        return $.get('/weather/searchCity/?q=%QUERY', { query: query }, function (data) {
            var matches = [];
            $.each(data, function(i, str) {
                matches.push({ value: str });
            });
            return process(matches);

        },'json');
    }
});

对于那些正在寻找公认答案的咖啡脚本版本的人:

$(".typeahead").typeahead source: (query, process) ->
  $.get "/typeahead",
    query: query
  , (data) ->
    process data.options
