ASPUpload获取表单元素的说明
作者:admin 日期:2008-04-29
众所周知，ASPUpload可以用来上传文件至服务器，当然，也可以用来获取表单元素的内容。前几天测试学习ASPUpload组件时一般都在上传文件的同时混有表单元素的传送，也没出现什么问题，今天突然想如果只用ASPUpload获取表单元素内容而没有上传文件，那可不可以不用调用Save方法？输入下边代码进行测试：
程序代码
<%
Dim Upload,Upfile
Set Upload = Server.CreateObject("Persits.Upload")
Response.Write(Upload.Form("text1"))
Set Upload = nothing
%>
Dim Upload,Upfile
Set Upload = Server.CreateObject("Persits.Upload")
Response.Write(Upload.Form("text1"))
Set Upload = nothing
%>
结果无法取到表单text1的值，加入Upload.Save后就正常了：
程序代码
<%
Dim Upload,Upfile
Set Upload = Server.CreateObject("Persits.Upload")
Upload.Save
Response.Write(Upload.Form("text1"))
Set Upload = nothing
%>
Dim Upload,Upfile
Set Upload = Server.CreateObject("Persits.Upload")
Upload.Save
Response.Write(Upload.Form("text1"))
Set Upload = nothing
%>
是不是在调用Form方法前必须先得调用Save方法？网上搜索了一番，最终在CSDN上看到了一句话：We must call Upload.Save or SaveVirtual before we can use Upload.Form!，在ASPUpload安装文件夹中搜索此句，位于Samples\02_simple\UploadScript3.asp第16行，此行为一注释语句。
