How to display Success message after clicking Save in HTML page - html

Question

I have an html form containing this code which runs on IIS:
<form action="http://server1/data.asp" method="POST">
Your Name: <input name="name" type="text">
<input value="Save" type="submit">
</form>
After user submits this form it runs the code in data.asp which displays a Success message with code to write to a text file (file1.txt):
Success!
<%
Dim fso
Dim tst
Set fso=Server.CreateObject("Scripting.FileSystemObject")
Set tst = fso.OpenTextFile("C:\Inetpub\wwwroot\data\file1.txt", 8, true)
tst.writeline "Name = " & Request.Form("name")
tst.writeline "" & Request.Form("")
tst.close
Set tst = Nothing
Set fso = Nothing
%>
This works but it just shows a page with Success! and stays there. What I'd really like is:
After user submits the form by clicking Save I'd like a little message box that says "Success" and remain on the same html page or go to a url I specify within the code.
I don't want to use Java or 3rd party extensions. This is an HTML page that runs the data.asp page on submit and I'd like it to stay that way if possible.
So how would I modify the html and/or data.asp page to do this?

Answer 1

You can do like this:
Response.Redirect "https://www.yoursite.com/thankyou.asp"

Answer 2

Instead of returning "Success!" as your response content you can return the form content you have above, this way you can use the same file for the GET and POST methods, with an condition on your asp logic to execute only on POST requests and return a success alert when the code is excuted successfully.
<form action="http://server1/index.asp" method="POST">
Your Name: <input name="name" type="text">
<input value="Save" type="submit">
</form>
<%
If (Request.Method = "POST") Then
Dim fso
Dim tst
Set fso=Server.CreateObject("Scripting.FileSystemObject")
Set tst = fso.OpenTextFile("C:\Inetpub\wwwroot\data\file1.txt", 8, true)
tst.writeline "Name = " & Request.Form("name")
tst.writeline "" & Request.Form("")
tst.close
Set tst = Nothing
Set fso = Nothing
response.write ("<script>alert('Success!');</script>")
End If
%>

Answer 3

Found the solution by adding an extra page to the mix (redir2form.asp):
in data.asp:
<%
Dim fso
Dim tst
Set fso=Server.CreateObject("Scripting.FileSystemObject")
Set tst = fso.OpenTextFile("C:\Inetpub\wwwroot\data\file1.txt", 8, true)
tst.writeline "Name = " & Request.Form("name")
tst.writeline "" & Request.Form("")
tst.close
Set tst = Nothing
Set fso = Nothing
%>
Response.Redirect "http://server1/redir2form.asp"
in redir2form.asp:
<%
response.write ("<script>alert('Success!');</script>")
%>
<meta http-equiv="refresh" content="1; url=http://server1/index.htm" />
Index.htm has the form action going to the data.asp page.
Not as neat as it could be but that's how I got it to work. After a user submits the form he gets the "Success!" message box and once they click OK they're redirected back to the form page.
