Synopsis

document.URL

Description

URL
is a read-only string property that contains the complete URL of the
current document.

document.URL is usually
equal to
window.location.href
for the window that contains
document. These two are not always equal,
however, because the Document.URL property may be
modified through URL
redirection -- Window.location contains the
requested URL, and Document.URL specifies the
actual URL where it was found.

Usage

Some web authors like to include the URL of a document somewhere
within the document so, for example, if the document is
cut-and-pasted to a file or printed out, there is still a reference
to its location online. The following script, when appended to a
document, automatically adds the document's URL:

<script>
document.write('<p><hr><small><i>URL: ' + document.URL
+ '</i></small>');
</script>
