javascript - Typeahead.js - 无法选择建议

Question

我一定是个白痴。我正在使用Typeahead.js插入。我正在尝试使用自定义模板来获取建议。当我的自定义模板出现时，我无法使用箭头键实际选择项目。如果我将鼠标悬停在某个项目上，该选择也不会突出显示。我认为这可能只是一个样式问题。但是，如果出现 3 个建议，并且我单击向下箭头两次，然后输入，我选择的选项不会出现在文本框中。或者，如果我用鼠标选择一个选项，该选项不会出现在框中。

我做错了什么？目前，我有以下内容:

var suggestions = new Bloodhound({
  datumTokenizer: Bloodhound.tokenizers.obj.whitespace('value'),
  queryTokenizer: Bloodhound.tokenizers.whitespace,
  remote: {
    url: '/api/suggests?querytext=%QUERY',
    filter: function(results) {
      return $.map(results.Results, function(suggestion) {
        return suggestion;
      });
    }
});
suggestions.initialize();

$(document).ready(function() {
  $('input.typeahead').typeahead(
    { minLength: 3 },
    {
      name: 'suggestions',
      source: suggestions.ttAdapter(),
      templates: {
        suggestion: function(data) {
          var str = '';
          if (data.Type === 'Customer') {
            str += '<i class="icon-1"></i>';
          } else if (data.Type === 'Product') {
            str += '<i class="icon-2"></i>';
          }
          str += '<div>' + data.Name + '</div>';
          return str;
        }
      }
    }
  );
});

弹出建议。结果来自以下 JSON:

{
  "Results":[
    {
      "Type":"Customer",
      "Id":5,
      "Name":"Bill",
      "LastUpdated":"01-01-2015"
    },
    {
      "Type":"Customer",
      "Id":135,
      "Name":"Billows",
      "LastUpdated":"01-02-2015",
    },
    {
      "Type":"Product",
      "Id":241,
      "Name":"Bill Check",
      "LastUpdate":"01-04-2015"
    }
  ],
  "TotalResults":3,
  "TotalCustomers":2,
  "TotalProducts":1
}

如何 a) 当用户将鼠标悬停在项目上或使用箭头键到达项目时，对项目应用突出显示 b) 将所选项目的 Name 值放入选择建议时的输入框？

谢谢!
