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

更新:我修改了我的代码使用这个分叉

也不是使用$。每一个我都换成了$。由托米斯拉夫·马可夫斯基推荐的地图

$('#manufacturer').typeahead({
    source: function(typeahead, query){
        $.ajax({
            url: window.location.origin+"/bows/get_manufacturers.json",
            type: "POST",
            data: "",
            dataType: "JSON",
            async: false,
            success: function(results){
                var manufacturers = new Array;
                $.map(results.data.manufacturers, function(data, item){
                    var group;
                    group = {
                        manufacturer_id: data.Manufacturer.id,
                        manufacturer: data.Manufacturer.manufacturer
                    };
                    manufacturers.push(group);
                });
                typeahead.process(manufacturers);
            }
        });
    },
    property: 'name',
    items:11,
    onselect: function (obj) {

    }
});

然而，我遇到了一些问题

无法调用undefined的方法“toLowerCase”

正如你在一个新的帖子上看到的，我正在试图弄清楚

希望这个更新对你有任何帮助…

您可以使用支持ajax调用的BS Typeahead fork。 然后你就可以这样写了:

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

我没有一个可行的例子，也没有一个非常清晰的解决方案，但让我告诉你我的发现。

如果你看一下TypeAhead的javascript代码，它是这样的:

items = $.grep(this.source, function (item) {
    if (that.matcher(item)) return item
  })

这段代码使用jQuery“grep”方法来匹配源数组中的元素。我没有看到任何可以在AJAX调用中挂钩的地方，所以没有一个“干净”的解决方案。

However, one somewhat hacky way that you can do this is to take advantage of the way the grep method works in jQuery. The first argument to grep is the source array and the second argument is a function that is used to match the source array (notice Bootstrap calls the "matcher" you provided when you initialized it). What you could do is set the source to a dummy one-element array and define the matcher as a function with an AJAX call in it. That way, it will run the AJAX call just once (since your source array only has one element in it).

这种解决方案不仅很棘手，而且还会出现性能问题，因为TypeAhead代码被设计为对每一次按键都进行查找(AJAX调用实际上应该只在每几次按键或在一定的空闲时间之后发生)。我的建议是尝试一下，但是坚持使用不同的自动补全库，或者如果遇到任何问题，只在非ajax的情况下使用它。

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');
    }
});
