Including VBScript Code as External Files

This section provides a quick description of how to save VBScript code into separate files and include them into HTML documents with 'script' tags. A tutorial example is provided on calling a function stored in a separate VBScript file.

Sometime, if you have a large amount of VBScript code that needs to be shared by multiple HTML documents, you can store the VBScript code in a separate file, and use the "script" tag to retrieve this tile.

The syntax of the "script" tag to retrieve a separate VBScript code file looks like this:

<script type="text/vbscript" src="VBScript_file_URL">
</script>

To test this feature, I wrote this VBScript code and saved as a file, Hello_World_Function.vbs:

function printHello()
   document.write("Hello World!")
end function

Now I can modify my HTML document in the previous section to retrieve this file with a "script" tag:

<html>
<!-- Hello_World_Include.html
 - Copyright (c) 2015, HerongYang.com, All Rights Reserved.
-->
<head>
<title>printHello() Function in an Include File</title>
<script type="text/vbscript" src="Hello_World_Function.vbs">
</script>
</head>
<body>
<pre>
<script type="text/vbscript">
   printHello()
</script>
</pre>
</body>
</html>

Of course, the output of the modified VBScript page will be the same text: "Hello World!".

While testing this "src" attribute of the "script" tag, I also notice that the shorthand form of the empty tag does not work:

<script type="text/vbscript" src="VBScript_file_URL"/>

You must use the close tag </script> explicitly!
