Figure 14.11
Demonstration of
onmouseover with
mouseovertest.html
Move the mouse pointer away from the link. As soon as the mouse pointer is no longer
on the link, the mouseout event occurs and the onmouseout event handler is triggered.
This displays the alert box, as shown in Figure 14.12.
Figure 14.12
Demonstration of
onmouseout with
mouseovertest.html
You can combine event handlers in one hypertext link. This is the essence of the image
swapping technique. The onmouseover event handler changes the image to a new image
and the onmouseout event handler changes the image back to the original image. This
technique is beyond the scope of this chapter, but perhaps this demonstration sheds
some light on how image swapping is accomplished.
