Description
Theonmouseup attribute is the counterpart to the
onmousedown attribute. It triggers an event when
the user releases the mouse button while the cursor is positioned over the
element to which the attribute is applied. Just as
onmousedown is not greatly used, its partner
onmouseup isn’t common.
Note that this event attribute cannot be applied to the following elements:

Example
The event handler for
onmouseup event calls the function
unHighlightThis:
<div onmousedown="highlightThis();" onmouseup="unHighlightThis();">Holiday
dates for 2008</div>
Value
This attribute has no fixed value.
It’s up to the author to decide on the scripting that’s included here, be
that a call to one or more defined functions, or a simple
alert() statement.

Every browser listed supports this attribute. However, inline event handlers such as this should be avoided. In the same way that inline CSS styles are frowned upon but externally defined CSS styles are considered good practice, inline event handlers should be stripped out and replaced with events attached unobtrusively through the DOM.
