Examples

This example uses the onmouseout event to apply a new style to an object.
<BODY>
<P onmouseout="this.style.color='black';"
onmouseover="this.style.color='red';">
Move the mouse pointer over this text, and then move it elsewhere
in the document. Move the mouse pointer over this text, and then
move it elsewhere in the document.
</BODY>
This example shows how to swap images on mouse events.
<SCRIPT>
function flipImage(url)
{
if (window.event.srcElement.tagName == "IMG" )
{
window.event.srcElement.src = url;
}
}
</SCRIPT>
</HEAD>
<BODY>
<P>Move the mouse over the image to see it switch.<P>
<IMG SRC="../common/prop_ro.gif"
onmouseover="flipImage('../common/prop_rw.gif');"
onmouseout="flipImage('../common/prop_ro.gif');"
</BODY>
