通过页面实现多文件上传，并有进度条控制的例子，步骤参考如下（代码中涉及的几个按钮图片参见附件）
1：页面端实现多文件上传
<%@ page language=
"java"
contentType=
"text/html; charset=UTF-8"
pageEncoding=
"UTF-8"
session=
"false"
%>
<%
String Bizid = request.getParameter(
"BizID"
);
String Typeid = request.getParameter(
"typeid"
);
String ID = request.getParameter(
"ID"
);
String Filetitle = request.getParameter(
"Filetitle"
);
%>
method=
"post"
enctype=
"multipart/form-data"
onsubmit=
"return TiJiao()"
>

2：文件上传要用到的css
.fileInputContainer{
background:url(../style/youlan.png) no-repeat;
}
.fileupload{
width:350px;
height:27px;
right:
0
;
top:
0
;
opacity:
0
;
filter:alpha(opacity=
0
);
cursor:pointer;
}
.shangchuan{
background:url(../style/shangchuan.png);
width:62px;
height:26px;
border:
0
;
padding:
0
;
float
:right;
margin-right:10px;
}
.quxiao{
background:url(../style/quxiao.png);
width:62px;
height:26px;
border:
0
;
padding:
0
;
float
:right;
margin-right:10px;
}
.yichu{
width:62px;
height:26px;
border:
0
;
padding:
0
;
background:url(../style/yichu.png);
}
.progressbar{
position:relative;
background:#AAAAAA;
width:
98
%;
height:16px;
overflow:hidden;
}
.progressbar-percent{
position:absolute;
height:18px;
background:#00FF00;
left:
0
;top:0px;
overflow:hidden;
z-index:
1
;
}
.progressbar-label{
position:absolute;
left:
0
;
top:
0
;
width:
90
%;
font-size:13px;
color:White;
z-index:
10
;
text-align:center;
height:16px;
line-height:16px;
}
