还得记得引入jquery,weui.css,weui.js呀

html:

 <div class="weui-cells weui-cells_form" id="uploader">
     <div class="weui-cell">
         <div class="weui-cell__bd">
             <div class="weui-uploader">
                 <div class="weui-uploader__hd">
                     <p class="weui-uploader__title">图片上传</p>
                     <div class="weui-uploader__info"><span id="uploadCount">0</span>/5</div>
                 </div>
                 <div class="weui-uploader__bd">
                     <ul class="weui-uploader__files" id="uploaderFiles"></ul>
                     <div class="weui-uploader__input-box">
                         <input id="uploaderInput" class="weui-uploader__input" type="file" accept="image/*" capture="camera" multiple="" />
                     </div>
                 </div>
             </div>
         </div>
     </div>
 </div>
