Including VBScript Code with HTML "script" Tags

This section provides a quick description of how to include VBScript code into HTML documents with 'script' tags. A tutorial example is provided on calling a function defined in the 'head' tag.

If you want have VBScript code to be executed by IE browser on the client systems, you need to embed VBScript code in HTML documents to be delivered to IE browser.

HTML document language standard supports the "script" tag that allows you to include VBScript code in HTML documents. Both forms of the "script" tag work identically:

<script language="vbscript" ...>
   ... VBScript statements ...
<script type="text/vbscript" ...>
   ... VBScript statements ...

In a single HTML document, multiple "script" tags with VBScript code can be placed in different locations. The exact locations and relations of "script" tags are described in following simple rules:

Based these rules, we could define a user function in the "head" tag of the document, and call it later in a "pre" tag in the same document. Here is a simple tutorial example that shows this interesting behavior:

<!-- Hello_World_Head.html
 - Copyright (c) 1998 All Rights Reserved.
<title>printHello() Function in the "head" Tag</title>
<script type="text/vbscript">
function printHello()
   document.write("Hello World!")
end function
<script type="text/vbscript">

Of course, the output of this sample VBScript page will be a simple text on the page: "Hello World!".
