DOM API - The "window.open" Method

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 built-in object "window" also allows you to create a new browser window and returns a new window object. You can manipulate the new browser window through this object.

Here is JavaScript tutorial example that uses the window.open() method to create a new window:

<head>
<title>Window Object</title>
<script type="text/javascript">
var mySize = 0;
var myWin;

function openWin() {
   myWin = window.open('','','left=300,top=100,width=600,height=600');
   myWin.focus();
}

function changeSize() {
   if (mySize == 0 )
      myWin.resizeTo(300,300); 
   else if (mySize == 1 )
      myWin.resizeTo(400,400); 
   else if (mySize == 2 )
      myWin.resizeTo(500,500); 
   else if (mySize == 3 )
      myWin.resizeTo(600,600); 
   mySize = (mySize+1)%4;
   myWin.focus();
}

function closeWin() {
   myWin.close();
}

</script>
</head>
<body>
<p>Click "Create Window" first start the test:</p>
<p><form>
  <input type="button" value="Create Window" onClick="openWin();"/>
  <input type="button" value="Resize Window" onClick="changeSize();"/>
  <input type="button" value="Close Window" onClick="closeWin();"/>
</form></p>
</body>
</html>
