通过搜索输入以列表形式返回结果

Question

朋友，我正在尝试学习如何进行“简单的”搜索输入。

我有八个选项的列表，并且想制作一个JS函数来帮助我隐藏与搜索不匹配的选项。

<div class="search__dropdown">
    <div class="search__dropdown-header">
        <h3 class="search__dropdown-title">Hostel</h3>
    </div>
    <div class="search__dropdown-body">
        <input class="search__dropdown-input search__dropdown-input--search" type="text" placeholder="Procure" />
        <ul class="search__dropdown-list search__dropdown-list--hostel">
            <li class="search__dropdown-item">
                <input class="search__dropdown-checkbox" name="hostel1" type="checkbox" id="hostel1" />
                <label class="search__dropdown-label" for="hostel1">one</label>

Answer 1

1. 附加input事件以触发每个字母更改
2. 遍历列表项并检查其文本是否包含当前值
3. 如果没有，请隐藏该项目

 $('.search').on('input', function() { var search = $(this).val(); var options = $('li:has([name*="hostel"])'); options.each(function() { $(this).show(); if ($(this).find('[for*="hostel"]').text().indexOf(search) < 0) { $(this).hide(); } }); });
