Below I will share with you an example of JavaScript using mouseover() to achieve the image enlargement effect. It has a good reference value and I hope it will be helpful to everyone.

Example As shown below:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> 
<html xmlns="http://www.w3.org/1999/xhtml"> 
<head> 
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> 
<title>图片提示</title> 
<!--jQuery --> 
<script src="../jquery.min.js"type="text/javascript"></script> 
<style type="text/css"> 
body{ 
margin:0; 
padding:40px; 
background:#fff; 
font:80% Arial, Helvetica, sans-serif; 
color:#555; 
line-height:180%; 
} 
img{border:none;} 
ul,li{ 
margin:0; 
padding:0; 
} 
li{ 
list-style:none; 
float:left; 
display:inline; 
margin-right:10px; 
border:1px solid #AAAAAA; 
} 
/* tooltip */ 
#tooltip{ 
position:absolute; 
border:1px solid #ccc; 
background:#333; 
padding:2px; 
display:none; 
color:#fff; 
} 
</style> 
<script type="text/javascript"> 
$(document).ready(function(){ 
var x=1,y=1; 
var myHref; 
$("a[class=tooltip]").mouseover(function(e){//鼠标悬停的时候 
myHref=this.href;//获取大图片 
var $p=$("<p id=&#39;tooltip&#39;><img src=&#39;"+myHref+"&#39;></img></p>");//创建一个p 
$("body").append($p);//把p添加到body中 
$("#tooltip").css({ 
top:e.pageY+y+"px", 
left:e.pageX+x+"px" 
}).show("slow"); 
}).mouseout(function(e){//鼠标移开的时候 
$("#tooltip").remove(); 
}).mousemove(function(e){//鼠标移动的时候 
$("#tooltip").css({ 
top:e.pageY+y+"px", 
left:e.pageX+x+"px" 
}).show("slow"); 
}) 
}); 
</script> 
</head> 
<body> 
<ul> 
<li><a href="02121.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="tooltip" ><img src="02121.png" /></a></li> 
<li><a href="02121.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="tooltip" ><img src="02121.png" /></a></li> 
<li><a href="02121.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="tooltip" ><img src="02121.png" /></a></li> 
<li><a href="02121.png" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" class="tooltip" ><img src="02121.png" /></a></li> 
</ul> 
<br/><br/><br/><br/> 
<br/><br/><br/><br/>
</body> 
</html>

The above is what I compiled for everyone. I hope it will be helpful to everyone in the future.
