HTML

<div class="mui-content">            <button type="button" class="mui-btn mui-btn-blue mui-btn-block" id="bt1">搜索设备</button>            <div class="mui-content-padded">                未配对蓝牙设备                <ul class="mui-table-view" id="list1">                </ul>            </div>        </div>
