DOM API - The "window" Object

This section provides a quick description of the 'window' object of the DOM API. A tutorial example is provided on changing browser window size through the 'window' object.

The DOM API provided by IE browser contains another useful object called "window", which has the following features:

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

<html>
<!-- Window_Object.html

-->
<head>
<title>Window Object</title>
<script type="text/vbscript">
dim sizeID
sizeID = 0
function changeSize()
   if sizeID = 0 then
      window.resizeTo 300,300 
   elseif sizeID = 1 then
      window.resizeTo 400,400  
   elseif sizeID = 2 then
      window.resizeTo 500,500  
   elseif sizeID = 3 then
      window.resizeTo 600,600  
   end if
   sizeID = (sizeID+1) mod 4
end function
</script>
</head>
<body>
<p>Hello World!</p>
<p><form>
  <input type="button" value="Change" onClick="changeSize()"/>
</form></p>
</body>
</html>

Run this VBScript example in a Web browser, and click the "Change" button. The browser window will change its size each time you click the button.

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