Events

Description:

Events are things that can occur within an element. These include mouse clicks and movement, document loading and anything else that can happen in the area bounded by a tag. An event is valid on most tags, and they are specified in this reference wherever they may be used.

Attributes:

ondblclick=JavaScript
	Specifies JavaScript code to be executed when a double-click is detected anywhere in the element.
onblur=JavaScript
	Specifies JavaScript code to be executed when the window of the document loses focus.
onfocus=JavaScript
	Specifies JavaScript code to be executed when the window of the document gains focus.
onkeydown=JavaScript
	JavaScript to be executed when a key is pressed in anywhere in the element.
onkeyup=JavaScript
	JavaScript to be executed when a key is pressed and then released in anywhere in the element.
onmousedown=JavaScript
	If a mouse button is pushed down anywhere in the element, then this JavaScript is executed.
onmousemove=JavaScript
	If the mouse moves anywhere in the element, then this JavaScript is executed.
onmouseout=JavaScript
	If the mouse moves out of the element, then this JavaScript is executed.
onmouseover=JavaScript
	If the mouse moves over an element, then this JavaScript is executed.
onload=JavaScript
	Specifies JavaScript code to be executed when the page is loaded.
onunload=JavaScript
	Specifies JavaScript code to be executed when the page is unloaded.

Examples:

<A HREF="/member/privacy.html" onMouseOver="self.status='Privacy Policy';
return true;" onMouseOut="self.status='';return true;">Privacy Policy</A>

This code creates a link with the label "Privacy Policy". When the mouse is moved to any of the text "Privacy Policy" (onMouseOver), the variable "self.status" is set to "Privacy Policy" (this sets the value of the status line on the lower left of the browser window). When the mouse moves away from the text the status line is erased.

Tips:

Remember events are newer elements in HTML and are not supported by older browsers.
In addition, if someone disables JavaScript then the JavaScript code will not be executed.
