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 1.2; HTML 4.0
Synopsis
<element onmousedown="handler" ... >element.onmousedown
Description
The onmousedown property of an HTMLElement object
specifies an event handler function that is invoked when the user
presses a mouse button over element.
The initial value of this property is a function that contains the
JavaScript statements specified by the onmousedown
attribute of the HTML tag that defined the object. When an event
handler function is defined by an HTML attribute, it is executed in
the scope of element rather than in the
scope of the containing window.
In the Netscape 4 event model, the onmousedown
handler function is passed an Event object as an argument. In the IE
event model, no argument is passed, but the applicable Event object
is available as the event property of the Window
object that contains the element.
In Netscape, the Event.which property specifies
which mouse button was pressed. In IE, the
Event.button property specifies the button number.
