4个文件实现无组件上传4个文件实现无组件上传
嵌套式调用:
<iframe name="ad" frameborder=0 width=100% height=50 scrolling=no src=uploada.asp></iframe>
直接链接:uploada.asp
文件保存路径:upload
上传文件类型和大小自己设置
===========================================
第一个文件:inc/confing.asp(inc为文件夹名称)
<%
Const EnableUploadFile="Yes" '是否开放文件上传
Const MaxFileSize=200 '上传文件大小*
Const UpFileType="gif|jpg|bmp|png|swf|doc|txt|rar|zip" '允许的上传文件类型
%>
