Question

我一定是个白痴。我正在使用Typeahead.js插件。我正在尝试使用自定义模板来提供建议。当我的自定义模板出现时，我无法使用箭头键来实际选择项目。如果我将鼠标悬停在某个项目上，则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，则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，则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;
        }
      }
    }
  );
});

建议弹出窗口。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
}

我如何a）当用户使用鼠标悬停在某个项目上时使用突出显示或使用箭头键进入该项目b）将选择项目的Name值添加到项目中选择建议时的输入框？

谢谢！

Answer 1

您是否尝试将valueKey添加到指向其名称的函数中？请参见这里的答案：

Typeahead.js does give me suggestions but doesn't select them

Answer 2

尝试

$(function () {

    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 {value:suggestion.Name, suggest:suggestion};
          });
        }
    });
    suggestions.initialize();


    $("#bloodhound .typeahead").typeahead({
        minLength: 3,
