This article explains one possible way to write Active Server Pages (ASP)
code using VBScript to provide a recursive functionality within your ASP
page.
Recursive means that the ASP page calls itself to continue with
functionality. In the example below, the page posts form values to
itself for processing. This is by no means necessary in all applications;
it is merely provided as a more robust method to achieve functionality. One
advantage to this method is fewer ASP pages to maintain. For example, a
developer can make a self-contained "wizard" all in one ASP page.
This sample demonstrates the functionality with one post to itself.
Paste this code in a plain text document, and save it as "Recursive.asp."
<%@ LANGUAGE="VBSCRIPT" %>
<%
submitted = Request.Form("frmSubmit")
%>
<HTML>
<HEAD>
<TITLE>Recursive Example</TITLE>
</HEAD>
<BODY>
<%
If submitted <> "yes" Then
%>
<h3>Recursive Example</h3>
<form action="<%=Request.Servervariables("SCRIPT_NAME")%>" method="post"
name="myForm">
<input type="hidden" name="frmSubmit" value="yes">
Please enter some text:<br><input type="text" name="frmInput"><p>
<input type="submit" name="myButton" value="Click here to continue">
</BODY>
</HTML>
<%
ElseIf submitted = "yes" Then
%>
<h3>Form Has been submitted</h3>
This is the information you submitted:<p>
<%=Request.Form("frmInput")%>
</BODY>
</HTML>
<%
End If
%>
