This fourth edition of the definitive reference to
JavaScript, a scripting language that can be embedded
directly in web pages, covers the latest version of the
language, JavaScript 1.5, as supported by Netscape 6 and
Internet Explorer 6. The book also provides complete
coverage of the W3C DOM standard (Level 1 and Level 2),
while retaining material on the legacy Level 0 DOM for
backward compatibility.
Availability
JavaScript 1.1
Synopsis
location.reload( )location.reload(force)
Arguments
force
A boolean argument that specifies whether the document should be
reloaded, even if the server reports that it has not been modified
since it was last loaded. If this argument is omitted, or if it is
false, the method reloads the full page only if it
has changed since last loaded.
Description
The reload(
) method of the Location object reloads the document that
is currently displayed in the window of the Location object. When
called with no arguments or with the argument
false, it uses the
If-Modified-Since HTTP header to determine whether
the document has changed on the web server. If the document has
changed, reload reloads the document from the
server, and if not, it reloads the document from the cache. This is
the same action that occurs when the user clicks on the
browser's Reload button.
When reload( ) is called with the argument
true, it always bypasses the cache and reloads the
document from the server, regardless of the last-modified time of the
document. This is the same action that occurs when the user Shift -clicks on the browser's Reload button.
