Typeahead 0.11.1 查看下拉搜索结果时鼠标悬停和键盘冲突

Question

我已经实现了 Twitter 的 Typeahead.js 功能来显示搜索结果建议，它工作正常，但是当我使用键盘突出显示一个建议然后将光标移动到另一个建议时，问题就来了。以下是一些解释问题的图片：

当鼠标光标悬停在另一个选择上时，以及如果鼠标已经悬停在一个建议上，我如何删除键盘选择，如果我在键盘上按 up/down，鼠标选择会消失，并且选择分别移动up/down?

.tt-job-company {
  font-size: 12px;
  font-weight: normal;
}

顺便说一句，我正在使用 Bootstrap 3（它与 Typeahead v0.11.1 不兼容）因此很长 CSS.

Answer 1

添加

    $('.twitter-typeahead').on('mouseover', '.tt-suggestion', function(event){
        $('.tt-tag').removeClass('tt-cursor');
        $(this).addClass('tt-tag-hover');
    });

    $('.twitter-typeahead').bind('typeahead:cursorchange', function (ev, suggestion){
        $('.tt-tag').removeClass('tt-tag-hover');
    });

到您的脚本，并将以下 class 添加到 css，同时删除 .tt-menu tt-suggestion:hover class

.tt-tag-hover:hover {
  text-decoration: none;
  outline: 0;
  background-color: #f5f5f5;
  color: #262626;
}
