Example 5—Rollovers
A rollover is an effect in which one image is replaced for another when the user moves the mouse pointer over it. Often, this is used only with images that host hyperlinks, but that isn't necessarily a rollover's only use. The following is an example:
<html>
<head>
<title>A Simple Page</title>
<script language="JavaScript">
<!-- Cloaking device on!
if (document.images)
{
img1 = new Image;
img2 = new Image;
img1.src = "img1.gif";
img2.src = "img2.gif";
}
else
{
img1 = "";
img2 = "";
document.imgSwap = "";
}
// Cloaking device off -->
</script>
</head>
<body>
<a href="moveon.htm" onMouseover="document.imgSwap.src = img2.src" onMouseout="document
.imgSwap.src = img1.src"> <img src="img1.gif" name="imgSwap" border="0"> </a> </body> ...Become an O’Reilly member and get unlimited access to this title plus top books and audiobooks from O’Reilly and nearly 200 top publishers, thousands of courses curated by job role, 150+ live events each month,
