** jQuery File Upload ** 确实不错，能满足要求，但是感觉文档不是很有好，没尝试成功。

有啥错误？我用的时候没遇到啥问题

#1 楼 @loveky 效果没出来，js、css 都引用了

#1 楼 @loveky 不知道是不是由于我哪没引用全，我先把我的操作列出来，希望能帮忙看看是哪出问题了：

1. 引用 js 及 css

   <link rel="stylesheet" type="text/css" href="../css/bootstrap.min.css" />
   <link rel="stylesheet" type="text/css" href="../css/style.css" />
   <link rel="stylesheet" type="text/css" href="../css/blueimp-gallery.min.css" />
   <link rel="stylesheet" type="text/css" href="../css/jquery.fileupload.css" />
   <link rel="stylesheet" type="text/css" href="../css/jquery.fileupload-ui.css" />
   
   <script language="javascript" src="../script/jquery.1.7.2.js"></script>
   <script type="text/javascript" src="../script/jquery.ui.widget.js"></script>
   <script type="text/javascript" src="../script/jquery.iframe-transport.js"></script>
   <script type="text/javascript" src="../script/jquery.fileupload.js"></script>
   

2. form 表单

   <form id="fileupload" action="//jquery-file-upload.appspot.com/" method="POST" enctype="multipart/form-data">
       <!-- Redirect browsers with JavaScript disabled to the origin page -->
       <noscript><input type="hidden" name="redirect" value="http://blueimp.github.io/jQuery-File-Upload/"></noscript>
       <!-- The fileupload-buttonbar contains buttons to add/delete files and start/cancel the upload -->
       <div class="row fileupload-buttonbar">
           <div class="col-lg-7">
               <!-- The fileinput-button span is used to style the file input field as button -->
               <span class="btn btn-success fileinput-button">
                   <i class="glyphicon glyphicon-plus"></i>
                   <span>Add files...</span>
                   <input type="file" name="files[]" multiple>
               </span>
               <button type="submit" class="btn btn-primary start">
                   <i class="glyphicon glyphicon-upload"></i>
                   <span>Start upload</span>
               </button>
               <button type="reset" class="btn btn-warning cancel">
                   <i class="glyphicon glyphicon-ban-circle"></i>
                   <span>Cancel upload</span>
               </button>
               <button type="button" class="btn btn-danger delete">
                   <i class="glyphicon glyphicon-trash"></i>
                   <span>Delete</span>
               </button>
               <input type="checkbox" class="toggle">
               <!-- The global file processing state -->
               <span class="fileupload-process"></span>
           </div>
           <!-- The global progress state -->
           <div class="col-lg-5 fileupload-progress fade">
               <!-- The global progress bar -->
               <div class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100">
                   <div class="progress-bar progress-bar-success" style="width:0%;"></div>
               </div>
               <!-- The extended global progress state -->
               <div class="progress-extended">&nbsp;</div>
           </div>
       </div>
       <!-- The table listing the files available for upload/download -->
       <table role="presentation" class="table table-striped"><tbody class="files"></tbody></table>
   </form>
   

3. js 脚本

   <script id="template-download" type="text/x-tmpl">
   {% for (var i=0, file; file=o.files[i]; i++) { %}
   <tr class="template-download fade">
       {% if (file.error) { %}
           <td></td>
           <td class="name"><span>{%=file.name%}</span></td>
           <td class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
           <td class="error" colspan="2"><span class="label label-important">{%=locale.fileupload.error%}</span> {%=locale.fileupload.errors[file.error] || file.error%}</td>
       {% } else { %}
           <td class="preview">{% if (file.thumbnail_url) { %}
               <a href="{%=file.url%}" title="{%=file.name%}" rel="gallery" download="{%=file.name%}"><img src="{%=file.thumbnail_url%}"></a>
           {% } %}</td>
           <td class="name">
               <a href="{%=file.url%}" title="{%=file.name%}" rel="{%=file.thumbnail_url&&'gallery'%}" download="{%=file.name%}">{%=file.name%}</a>
           </td>
           <td class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
           <td colspan="2"></td>
       {% } %}
       <td class="delete">
           <button class="btn btn-danger" data-type="{%=file.delete_type%}" data-url="{%=file.delete_url%}">
               <i class="icon-trash icon-white"></i>
               <span>{%=locale.fileupload.destroy%}</span>
           </button>
           <input type="checkbox" name="delete" value="1">
       </td>
   </tr>
   {% } %}
   </script>
   

#2 楼 @xautjzd 我用了 jquery-fileupload-rails 这个 Gem

你效果没出来的话，可以看看浏览器的 console 中有没有报错信息

#4 楼 @loveky 好，thanks，我再看看

#5 楼 @xautjzd 哦，对了，还有一点，fileupload 这个 form 里跟这个插件相关的 DOM 结构不能随便改，它的 JS 绑定是依赖 DOM 结构的，我之前遇到过移动 DOM 元素然后就无法上传的情况 (而且 console 中不报错。。。)
