ajaxFileUpload上传多文件需要改源代码ajaxFileUpload.js，而且参数data上传到后台无数据。。。。
ajaxFileUpload.jsp

{
//校验文件格式
var tmpFileValue = $("#file").val();
if(!/^.*?.(gif|png|jpg|jpeg|bmp|doc|docx|xls|pdf|txt|mp3)$/.test(tmpFileValue.toLowerCase())){
alert("只能上传jpg、jpeg、png、bmp、gif、doc、docx、xls、pdf、txt、mp3格式的图片！");
return false;
}
var data = { username: 'my name'};
$("#loading")
.ajaxStart(function(){
$(this).show();
})//开始上传文件时显示一个图片
.ajaxComplete(function(){
$(this).hide();
});//文件上传完成将图片隐藏起来
$.ajaxFileUpload
(
{
url:'ajax/ajaxFileUploadAction.action',//用于文件上传的服务器端请求地址
type:'post',
secureuri:false,//一般设置为false
fileElementId:'file',//文件上传空间的id属性 <input type="file" id="file" name="file" />
dataType: 'json',//返回值类型 一般设置为json
data:data, //带参数传递，有问题。。后台接受不到

success: function (data,status) //服务器成功响应处理函数
{
alert(data.message);//从服务器返回的json中取出message中的数据,其中message为在struts2中定义的成员变量
if(typeof(data.error) != 'undefined')

if(data.error != '')
{
alert(data.error);
}else

alert(data.message);
