Using Enhanced <SCRIPT> Tags for Includes (224963)

Previous versions of IIS allowed an ASP page to include the contents of another file using code similar to the following:

<!--#include file="FILE1.INC"-->
<!--#include virtual="/folder/FILE2.INC"-->

IIS 5.0 has extended the server-side <SCRIPT> tag to include a new SRC attribute as an alternative method to include another page. The new syntax may then look similar to the following:

<SCRIPT LANGUAGE="VBSCRIPT" RUNAT="SERVER"
SRC="FILE.INC"></SCRIPT>

All code in the included page appears to the scripting engine as though it were between the <SCRIPT> and </SCRIPT> tags. Therefore, unlike the #include directive, your included page should consist of raw code only.

For example, consider the following #include statement:

<!--#include file="file.inc"-->

This statement would need to include a page similar to the following:

<%
  For X = 1 To 5
    Response.Write "<p>Howdy!</p>"
  Next
%>

Now consider the following <SCRIPT> statement:

<SCRIPT LANGUAGE="VBScript" RUNAT="SERVER"
SRC="file.inc"></SCRIPT>

This page would need to include a page similar to the following:

For X = 1 To 5
  Response.Write "<p>Howdy!</p>"
Next

The <SCRIPT> example is treated by ASP as though the parent page contains the following syntax:

<SCRIPT LANGUAGE="VBScript" RUNAT="SERVER" SRC="file.inc">
For X = 1 To 5
  Response.Write "<p>Howdy!</p>"
Next
</SCRIPT>

Note: No actual code should placed between the <SCRIPT> and </SCRIPT> tags in the parent page, as it will be ignored.

The SRC attribute can use either relative or virtual paths, as shown in the following table:

Path Style	Example Syntax
Relative	SRC="file.ext"
Relative	SRC="folder\file.ext"
Virtual	SRC="\folder\file.ext"
Virtual	SRC="/folder/file.ext"

The following ASP code demonstrates how to use the new <SCRIPT> syntax to mix server-side and client-side scripting.

Save the following ASP page as "ScriptTest.asp" to a Web folder with Script Access enabled:

<%@LANGUAGE="VBSCRIPT"%>
<html>
<head>
<title>Enhanced SCRIPT Example</title>
</head>
<body>
<h2 align="center">Enhanced SCRIPT Example</h2>

<p align="center">
<form method="GET" name="objForm"
action="<%=Request.ServerVariables("URL")%>">
  <input type="text" name="Message">
  <input type="submit" value="Submit">
</form>
</p>

<SCRIPT LANGUAGE="VBScript" RUNAT="SERVER"
SRC="server.inc"></SCRIPT>

<SCRIPT LANGUAGE="JavaScript">
<!--#include file="client.inc"-->
</SCRIPT>

</body>
</html>

Save the following code as "Server.inc" to the same folder:

Dim strMessage
strMessage = Request.QueryString("Message")
If strMessage <> "" Then
  Response.Write vbCrLf & "<script for=""window"" event=""onLoad"" language=""JavaScript"">"
  Response.Write vbCrLf & "objForm.Message.value = '" & strMessage & "';"
  Response.Write vbCrLf & "showMessage('" & strMessage & "');"
  Response.Write vbCrLf & "</script>"
End If

Next, save the following code as "client.inc" to the same folder:
```
function showMessage(strText) {
   alert(strText)
}
```

Notes:

- When you first browse "ScriptTest.asp," the form is displayed and the client-side function is not called.
- When you submit text to the page, the server-side script outputs another client-side function that displays the submitted text in the form's input box and in a pop-up window.
