搜索条未封装JS文件，要实现示例效果，请参照示例代码中的JS封装。

示例源码

<div class="aui-searchbar" id="search">
    <div class="aui-searchbar-input aui-border-radius">
        <i class="aui-iconfont aui-icon-search"></i>
        <input type="search" placeholder="请输入搜索内容" id="search-input">
        <div class="aui-searchbar-clear-btn">
            <i class="aui-iconfont aui-icon-close"></i>
        </div>
    </div>
    <div class="aui-searchbar-btn" tapmode>取消</div>
</div>
<section class="aui-content-padded">
    更新说明：取消了搜索条的绝对定位。增加清除按钮
</section>
<section class="aui-content-padded">
    要搜索的内容为：<span class="aui-text-info" id="search-keywords"></span>
</section>
