Algolia类型提前检索结果

Question

我试图在我的Rails应用程序中创建一个讨论工具。我想把用户添加到类似Facebook信使的讨论中。

为此，我实现了Algolia即时搜索sith Typeahead。它可以很好地显示结果，但是当我单击一个结果时，它什么也不做。看起来，如果我所使用的事件不起作用的话。

我不能用我的键盘上或下结果，这是非常奇怪的。你能帮我一下吗？我尝试了打字前文档中的所有事件，但没有人在工作。

非常感谢。

感谢伟大的阿尔戈利亚支持团队，我设法使它发挥作用！

正如建议的那样，我切换到了https://github.com/algolia/autocomplete.js，它非常完美。我改变了一些东西，基本上用.autocomplete和事件侦听器名称代替了.autocomplete。

下面是片段：

$inputfield.autocomplete({
      highlight: true,
      autoselect: true,
      openOnFocus: true
    }, [
      {
        source: $.fn.autocomplete.sources.hits(index, ttAdapterParams),
        displayKey: 'first_name',
        templates: {
          suggestion: function(hit) {
            var tpl = templates.algolia.hit.render(hit);
            //console.log(tpl, 'hit');
            return tpl;
          }
        }
      }]).on('autocomplete:selected', function(event, suggestion, dataset) {
        console.log(suggestion);
});
