javascript - 将表格添加到搜索结果自动完成下拉列表

标签 javascript jquery html css autocomplete

TLDR；如何在自动完成搜索下拉列表的左侧添加表格，如下图所示？

我的标题中有一个搜索栏，它使用 JS 函数根据一小部分示例产品自动完成。

我需要在下拉预览中添加标题和表格，但不知道在哪里插入 HTML，以便在搜索栏中输入内容时它会填充。

现在我已经对该示例的右侧进行了编码并正常运行。代码包含在下面。

HTML

        <div class="col-xs-12 col-sm-9 col-md-9 col-lg-9 search-block">
                        <div class="row">
  <form class="navbar-form suggest-holder">
   <input class="form-control input-lg suggest-prompt" type="text" placeholder="Search...">
     <select class="form-control input-lg">
      <option>All</option>
      <option>one</option>
      <option>two</option>
      <option>three</option>
      <option>four</option>
      <option>five</option>  

      <button type="submit" class="btn btn-primary btn-lg">Go</button>

      <ul></ul>
  </form>
</div>

CSS:

 .form-control {
 float: left;
 }

 .suggest-holder {

input {
    border: 1px solid $gray-lighter;
}

ul {
    list-style: none;
    border: 1px solid $gray-lighter;
    background-color: white;

    width:65%;
}

li {
    padding: 5px;
     position: inherit;
}

li:hover {
    cursor: pointer;
}

li:hover, li.active {
    background: rgba(100,100,100,.2);
}
}

最佳答案

只是想帮助你开始，你必须在以后改进它。

JS 已更新(这是为了更新 span 在 html 中有类 leftspan，所以把你想更新的任何东西放在 HTML 中):

  // update the left box below search
  $('.leftspan').html('<span class="searching"><b>' + $('.suggest-prompt').val() + '</b></span><i> in Category XXX</i>');

添加了 HTML(您可以看到结构更新为一个 div 容器包裹了 leftspan 和结果 ul block (使用 inline-block 所以它们保持在同一行)):

<form class="navbar-form suggest-holder">
      <input class="form-control input-lg suggest-prompt" type="text" placeholder="Search...">
      <select class="form-control input-lg">
        <option>All</option>
        <option>one</option>
        <option>two</option>
        <option>three</option>
        <option>four</option>
        <option>five</option>
      </select>
      <button type="submit" class="btn btn-primary btn-lg">Go</button>
      <div>
        <div class="leftspan"></div>
        <ul class="inlineblock">
        </ul>
      </div>
    </form>

添加了 CSS:

.inlineblock {
  display: inline-block;
}

.leftspan {
  margin: 15px;
  display: inline-block;
  float: left;
}

.searching {
  color: #428bca; /* blue */
}

var data = [{
