我很难找到typeahead.js来返回/渲染我页面上的所有结果。这是我的代码:

var places = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.whitespace,
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    remote: {
        url: '/api/place/?country={{ country.id }}&name=%QUERY'
        , transform: function (data) {
            return data.response;
        }
        , wildcard: '%QUERY'
    }
});

var selected = false;
$('.typeahead-place').typeahead({
    hint: true,
    highlight: true,
    minLength: 2
},
{
    name: 'places',
    displayKey: function (obj) {

        if (obj.url != null && obj.url.length && (obj.street == null || obj.street.length == 0)) {
            return obj.name + " (Online store)";
        }

        return obj.name + " (" + obj.street + ", " + obj.city + ", " + obj.postcode + ")";
    },
    source: places
});

Punn的示例查询让我从服务器返回JSON:

{
    "response": [
            {
                "id": "4",
                "name": "Punnitse ja Säästä 2",
                "street": "Simonkenttä, Simonkatu 9",
                "city": "Helsinki",
                "postcode": "00100",
                "url": "http://www.punnitse.fi/"
            },
    {
        "id": "12",
        "name": "Punnitse ja Säästä 3",
        "street": "Simonkenttä, Simonkatu 9",
        "city": "Helsinki",
        "postcode": "00100",
        "url": "http://www.punnitse.fi/"
    },
    {
        "id": "13",
        "name": "Punnitse ja Säästä 4",
        "street": "Simonkenttä, Simonkatu 9",
        "city": "Helsinki",
        "postcode": "00100",
        "url": "http://www.punnitse.fi/"
    },
    {
        "id": "9",
        "name": "Punnitse ja Säästä Kamppi",
        "street": "Simonkenttä, Simonkatu 9",
        "city": "Helsinki",
        "postcode": "00100",
        "url": "http://www.punnitse.fi/"
    }
    ]
}

现在这样呈现:

这似乎是typeahead.js新版本的well-known bug。为了使您的代码正常工作,您宁愿切换到版本 0.10.5 或更低版本,并稍微转换您的代码:

var places = new Bloodhound({
    datumTokenizer: Bloodhound.tokenizers.whitespace,
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    remote: {
        url: '/api/place/?country={{ country.id }}&name=%QUERY',
        wildcard: '%QUERY',
        filter: function(data) {      // <-- should use `filter`
            return data.response;
        }
    }
});

places.initialize();                  // <-- initialise suggestion

$('.typeahead-place').typeahead({
    hint: true,
    highlight: true,
    minLength: 2
}, {
    name: 'places',
    source: places.ttAdapter(),       // <-- get adapter as a source
    displayKey: function(obj) {
        // ...
    }
});

或者,如果您想坚持使用最新版本,可以将前一段时间发布的the following patch应用于typeahead.js的源代码。

我刚刚在这里找到了答案:https://github.com/twitter/typeahead.js/issues/1232提供的louy

...
$('.typeahead-place').typeahead({
    hint: true,
    highlight: true,
    minLength: 2,
    limit: Infinity
},
...

...也就是说,您需要设置Javascript全局 Infinity 属性的限制。这完全有效!

那就是说,他们还没有修补代码是犯罪行为 - 这个错误已经为所知。
