uploadify3.0 与 struts2结合
$("input[id][id^='file_']").each(function(i,obj) {$(obj).uploadify({'langFile': '${ctx}/static/js/jquery-uploadify/uploadifyLang_zh.js','swf' : '${ctx}/static/js/jquery-uploadify/uploadify.swf','uploader': '${ctx}/powerword/powerword_ajaxUpload.do',//servlet的路径或者.jsp 这是访问servlet 'scripts/uploadif' 'method' : 'get','postData': {'id':'${powerword.id}','audioId':''+$(obj).attr("id")},'fileObjName' : 'uploadify',//和input的name属性值保持一致就好，Struts2就能处理了 'cancelImage' : '${ctx}/static/js/jquery-uploadify/uploadify-cancel.png','auto' : true, //选定文件后是否自动上传，默认false'multi' : false, //是否允许同时上传多文件，默认false'queueID': "fileList_"+$(obj).attr("id"),'debug': false,'removeCompleted': false,'requeueErrors': false,'progressData': "all",'queueSizeLimit' : 1, //限制在一次队列中的次数（可选定几个文件）。默认值= 999，而一次可传几个文件有 simUploadLimit属性决定。'fileSizeLimit': 50*1024*1024, //设置单个文件大小限制，单位为byte ,50M'fileTypeDesc' : '支持格式:mp3', //如果配置了以下的'fileExt'属性，那么这个属性是必须的 'fileTypeExts' : '*.mp3',//允许的格式onUploadSuccess : function(file,data,response) { if(data){ var mp3 = eval('(' + data + ')');$("#label_"+$(obj).attr("id")).text(mp3.path); }},onUploadError : function(file,errorCode,errorMsg,errorString,swfuploadifyQueue) {$("#dialog-message").html(errorString);}});});?

一开始查了N多资料没有对3.0的文章,3.0与2.0+不一样的地方就是fileObjName这个属性的名字换了
还有可能我的struts2的配置跟网上的不太一样,最后调试了很长时间才调试通过
3 楼 fengzhiyu_sh 2012-05-15 'postData' : {'id':'${powerword.id}','audioId':''+$(obj).attr("id")},Struts2的Action中貌似无法获得传过来的参数啊？ 4 楼 jackyrong 2012-08-22 想问下，我的是struts2+uploadfit 3.1,文件能上传成功，
上传的时候，另外用formdata传递了表单的其他参数到sturts2的后台，
struts2的后台也能接受到文件，只不过struts2返回的是一个json（把表单的
另外的传递的参数原样子以JSON输出到前端而已，在uploadfiy
中，DEBUG模式下，也看到有：
File ID: SWFUpload_0_0 Response Received: true Data: {"version":"fdgfg"}
的字样，但是用：
'onUploadSuccess' : function(event, ID, fileObj, response, data) {
var mp3 = eval('(' + data + ')');
alert(data);
alert('The file ' + fileObj.name + ' was successfully uploaded with a response of ' + response + ':' + data);
}
打印出来的data和response都是空的？
