uploadify文件上传的使用

1.jsp代码

 1     appname=$("#appname").val();

 2         $("#uploadify").uploadify({

 3             'swf' : '<%=basePath%>/Backstage/Style/jQuery-uploadify/uploadify.swf',

 4             // 'script' : 'ProductAction!fileUpload.do',//后台处理的请求

 5             'uploader': 'AppVersionAction!fileUpload.do?appname='+appname , 

 6             'cancelImg' : '<%=basePath%>/Backstage/include/easyvalidator/images/vtip_arrow.png',

 7             'folder' : '/uplaod/temp',//您想将文件保存到的路径

 8             'queueID' : 'fileQueue',//与下面的id对应

 9             'fileObjName':'uploadify',

10             'queueSizeLimit' : 5,

11             'fileDesc' : '文件格式',

12             'fileTypeExts' : '*.apk;*.ipa;*.png', //控制可上传文件的扩展名，启用本项时需同时声明fileDesc

13             'auto' : false,

14             'multi' : true,

15             'simUploadLimit' : 2,

16             'buttonText' : '选择文件',

17             'onQueueComplete' : function(file,data,response) { 

18                   picFlag = true;  

19             }  

20         });

1     <input type="file" name="uploadify" id="uploadify" />

2                 <input id="appname" type="text" value="<s:property value="version.appName"/>" name="version.appName" size="30"   maxlength="32"  data-options="required:true,missingMessage:'请输入版本号'" class="easyui-validatebox" /><font color="red">&nbsp;*</font>
