Jquery上传插件uploadify的使用(JSP)版

来源:互联网 发布:开源大数据集成平台 编辑:程序博客网 时间:2024/06/05 02:56

今天,突然想研究下那个uploadify插件,在网上搜索好多资料,发现千奇百怪,可能是版本问题,关于服务端处理脚本我发现了两种说法,一种是通过‘script’来设置的,另一种是用‘uploadify’来设置的。我下面演示的是使用后者来设置服务端处理脚本的,插件版本为3.1版本

  1. 准备好uploadify 3.1版本的插件
  2. 建立一个web项目,并导入所需要的包,包括三个包(commons-fileupload-1.2.2.jar,commons-io-2.0.1.jar,commons-lang-2.5.jar)
  3. 写好JSP页面代码
  4. 创建后台处理的servlet
  5. 配置web.xml

红色圈住的部分本来应该放在css文件夹下,不过我喜欢将所有的uploadify插件的东西都放在一块。

index.jsp代码如下

<%@ page language="java" contentType="text/html; charset=utf-8"%>  <%          String path = request.getContextPath();          String basePath = request.getScheme() + "://"                  + request.getServerName() + ":" + request.getServerPort()                  + path + "/";      %>          <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">      <html>        <head>          <base href="<%=basePath%>">                    <title>文件上传</title>                 <link href="js/uploadify/uploadify.css" rel="stylesheet" type="text/css" />       <script type="text/javascript" src="js/jquery-1.8.3.min.js"></script>       <script type="text/javascript" src="js/uploadify/jquery.uploadify-3.1.min.js"></script>      <script type="text/javascript">      $(document).ready(function() {       $("#uploadify").uploadify({                      'auto'           : false,                      'swf'            : '<%=path%>/js/uploadify/uploadify.swf',                      'uploader'       : '<%=path%>/scripts/uploadify',//后台处理的请求                      'queueID'        : 'fileQueue',//与下面的id对应                      'queueSizeLimit' :3,                      'fileTypeDesc'   : 'rar文件或zip文件',                      'fileTypeExts'   : '*.rar;*.zip', //控制可上传文件的扩展名,启用本项时需同时声明fileDesc                      'multi'          : true,                      'buttonText'     : '上传'       });      });      </script>       </head>      <body>              <div id="fileQueue"></div>              <input type="file" name="uploadify" id="uploadify" />              <p>                  <a href="javascript:$('#uploadify').uploadify('upload')">开始上传</a>                   <a href="javascript:$('#uploadify').uplaodify('cancel','*')">取消上传</a>              </p>        </body>      </html>
