Uploadify上传onComplete事件有关问题

Uploadify上传onComplete事件问题 - Web 开发 / Ajax
用的是struts2+query1.4+uploadify2.1
上传都没什么问题
struts2返回json

就是在处理上传成功事件时

JScript code

 
 onComplete: function (event, queueID, fileObj, response, data) { 
 alert(response);//此处得到结果为   {"message","上传OK"} 
 alert(response.message);// 此处是null....为什么 
    　   alert("文件:" + fileObj.name + "上传成功"); 
    　} 
 

以下是action代码

Java code

public class UpLoadAction extends ActionSupport{    private File file;    private String fileFileName;    private String message;    public String getMessage() {        return message;    }    public void setMessage(String message) {        this.message = message;    }    public String execute(){        System.out.println("文件名是"+fileFileName+file);        String root=ServletActionContext.getServletContext().getRealPath("/upload");        try {            byte[]b=new byte[1024];            int length;            InputStream read=new FileInputStream(file);            OutputStream write=new FileOutputStream(new File(root,fileFileName));//文件名保存为例             while((length=read.read(b))!=-1){                write.write(b, 0, length);            }            read.close();            write.close();        } catch (FileNotFoundException e) {            // TODO Auto-generated catch block            e.printStackTrace();        } catch (IOException e) {            // TODO Auto-generated catch block            e.printStackTrace();        }        message="我是服务器";        return SUCCESS;    }    public void setFile(File file) {        this.file = file;    }    public void setFileFileName(String fileFileName) {        this.fileFileName = fileFileName;    }}

[解决办法]
scriptData
http://www.uploadify.com/documentation/

An object containing name/value pairs of additional information you would like sent to the upload script. {‘name’: ‘value’}
