上篇文章描述了单个文件的上传和配置，下面主要讲解下不同的地方：

index.jsp

 <head>      <script type="text/javascript">        function check(){            var file = document.getElementsByName("file");                var filename = document.getElementsByName("fileName");            var filetype = document.getElementsByName("fileType");            for(var i =0;i<file.length;i++){                if(file[i].value !=""){                      var f = file[i].value ;                           var type = f.substr(f.lastIndexOf(".")).toLowerCase();                    var name = f.substr(f.lastIndexOf("\\"));                    filename[i].value = name;                    filetype[i].value = type;                                          }else{                      alert("请选择文件");                    return false;                      }                    }            return true;        }    </script>  </head>    <body>        <p>stuts 2 多文件上传实例 </p>    ${requestScope.typeError}          <form action="/uploadMore.do" method="post" enctype="multipart/form-data" onsubmit="return check();">       上传文件1：<input type="file" name="file" /><br>                <input type="hidden" name="fileType"/><br>                <input type="hidden" name="fileName"/><br>     上传文件2：<input type="file" name="file" /><br>            <input type="hidden" name="fileType"/><br>                <input type="hidden" name="fileName"/><br>           <input type="submit" value=http://www.mamicode.com/"提交"/>      </form>      </body>
