DOM API - The "document" Object

This section provides a quick description of the 'document' object of the DOM API. A tutorial example is provided on building a simple HTML document with the 'document' object.

IE browser provides the DOM (Document Object Model) API (Application Programming Interface) to allow VBScript codes to interact with the browser and the HTML document.

The most commonly used object in the DOM API is the "document" object, which has the following features:

  • The "document" object is a browser built-in object that represents the current HTML document in the browser.
  • The "document" object represents all elements in the HTML document with tree structure of "node" objects.
  • The "document" object and its "node" objects offer various methods to allow you to manipulate the HTML document.
  • The "document" object share the same programming interface in VBScript and other programming languages.

To illustrate some nice features of the "document" object, I wrote this VBScript tutorial example:

<html>
<!-- Document_Object.html

-->
<head>
<title>Document Object</title>
<script type="text/vbscript">
function buildDocument()
   ' Building a <p> tag
   dim paragraph 
   set paragraph = document.createElement("p")
   dim text
   set text = document.createTextNode("Hello World!")
   paragraph.appendChild(text)

   ' Inserting the <p> tag
   document.body.appendChild(paragraph)
   document.body.bgColor = "lightblue"
end function
</script>
</head>
<body onLoad="buildDocument()"/>
</html>

If you run this VBScript page in a browser, you will see the "Hello World!" paragraph with light blue background.

For more tutorial examples on the "document" object, see the DOM API chapters in this book.
