W3cubDocs

window.document

window.document returns a reference to the document contained in the window.

Note: Firefox 3 alters the security for windows' documents so that only the domain from which it was located can access the document. While this may break some existing sites, it's a move made by both Firefox 3 and Internet Explorer 7, and results in improved security.

Syntax

doc = window.document

Parameters

doc is an object reference to a document.

Example

<!DOCTYPE html>
<html>
<head>
   <title>Hello, World!</title>
</head>
<body>

<script type="text/javascript">
   var doc = window.document;
   console.log(doc.title); // Hello, World!
</script>

</body>
</html>
