ASP多文件无组件上传
注意:本文最后更新于 2738 天前,有关的内容可能已经发生变化,请参考使用。
用了别人的类,挺不错的程序
需要的可以改改 通过遍历数据可以实现无组件上传多文件
对于访问量不大的中小站很有用 对于不能安装组件的虚拟主机就更有效了。。。
我发现这个类很强大
提取表单数据、上传到不同文件夹、保存到数据库(上传和保存表单可同时进行)、限制上传扩展名、限制上传大小、选择文件保存类型
具体如下
adm_upload.asp文件内容如下
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<LINK href="../css.css" type=text/css rel=stylesheet>
<style type="text/css">
<!--
BODY{
BACKGROUND-COLOR: #FFFFFF;
font-size:9pt
}
.tx1 { height: 20px;font-size: 9pt; border: 1px solid; border-color: #000000; color: #0000FF}
-->
</style>
<SCRIPT language=javascript>
function check()
{
var strFileName=form1.FileName.value;
var FileType;
if (strFileName=="")
{
alert("请选择要上传的文件");
return false;
}
}
</SCRIPT>
</head>
<body bgcolor="#FFFFFF" leftmargin="0" topmargin="0">
<%
dim fpath:fpath=request("fpath")
%>
<form action="adm_upfile.asp" method="post" name="form1" onSubmit="return check()" target="_self" enctype="multipart/form-data">

<input name="SUBMIT" type=SUBMIT class="btbg" value="上 传" />
</div> </td>
</tr>
</table>
</form>
</body><script>
function Addparts()
{
var row = parts.insertRow(parts.rows.length);//id=recordTable
var col = row.insertCell(0);
var i = row.rowIndex+2;
col.innerHTML = "文件"+ i + " <input type='file' name='file"+ i + "' value='' style='width:300px; margin-left:5px; margin-right:40px; text-align:center;' onpropertychange='checkFile(this)'>";
col = row.insertCell(1);
col = row.insertCell(2);
}
function checkFile(obj){
var oExten = obj.value.replace(/^.*\.([^\.]*)$/, '$1').toLowerCase();
if(oExten != 'jpg'&& oExten != 'gif'&&oExten!='bmp'&&oExten!='png'&&oExten!='rar'&&oExten!='doc'&&oExten!='xls'&&oExten!='txt'){
obj.outerHTML = obj.outerHTML;
