        <h2 class="title-detail">图片描述</h2><input type="hidden" id="picIndex" value="0"><div id='image-list' class="row image-list"><div class="image-item space" onclick="showActionSheet()"><div class="image-up"></div></div></div><script type="text/javascript" src="../js/saoyisao.js"></script><button type="button" onclick="showActionSheet()">点击我</button>

注: 要在Android手机上测试哦 浏览器里会报错的
