当使用具有远程选项的Typeahead / Bloodhound时,当本地/预取结果低于“限制”(5)时,显示的建议与输入无关.看起来喜欢它只是从结果设置的顶部显示为5.

照片：’爱’是预期的结果,其他一切都是无关的：

我的代码：

    var keywords = [
 {"value": "Ambient"}, {"value": "Blues"},{"value":  "Cinematic"},{"value":  "Classical"},{"value": "Country"},
 {"value": "Electronic"},{"value": "Holiday"},{"value": "Jazz"},{"value": "Lounge"},{"value": "Folk"},
  {"value": "Hip Hop"},{"value": "Indie"},{"value": "Pop"},{"value": "Post Rock"},{"value": "Rock"},{"value": "Singer-Songwriter"},{"value": "Soul"},
  {"value": "World"},{"value": "Happy"},{"value": "Sad"},{"value": "Love"},{"value": "Angry"},
  {"value":"Joy"},{"value": "Delight"},{"value": "Light"},{"value": "Dark"},{"value": "Religious"},{"value": "Driving"},
  {"value":"Excited"},{"value": "Yummy"},{"value": "Delicious"},{"value": "Fun"},{"value": "Rage"},
  {"value":"Hard"},{"value": "Soft"}
  ];


// Instantiate the Bloodhound suggestion engine
var keywordsEngine = new Bloodhound({
    datumTokenizer: function (datum) {
        return Bloodhound.tokenizers.whitespace(datum.value);
    },
    queryTokenizer: Bloodhound.tokenizers.whitespace,
    local: keywords,
    remote: {
        url: '/stub/keywords.json',
        filter: function (keywords) {
            // Map the remote source JSON array to a JavaScript object array
            return $.map(keywords, function (keyword) {
                return {
                    value: keyword.value
                };
            });
        }
    },
    prefetch: {
        url: '/stub/keywords.json',
        filter: function (keywords) {
            // Map the remote source JSON array to a JavaScript object array
            return $.map(keywords, function (keyword) {
                return {
                    value: keyword.value
                };
            });
        }
    }
});

// kicks off the loading/processing of `local` and `prefetch`
keywordsEngine.initialize();

$('#keyword-search-input').typeahead({
  hint: true,
  highlight: true,
  minLength: 1
},
{
  name: 'keyword',
  displayKey: 'value',
  // `ttAdapter` wraps the suggestion engine in an adapter that
  // is compatible with the typeahead jQuery plugin
  source: keywordsEngine.ttAdapter()
});

解决方法:

经过进一步研究,我认为我需要手动过滤远程建议,根据Github问题为Typeahead.js上的这个线程：

“所以我想这个想法是从遥控器返回的数据应该已经被遥控器过滤掉了,所以不再对它进行过滤.”
