错误代码如下：注意红色部分设置 （出发点就错了）
复制代码 代码如下:
<html>
<head>
<script type="text/javascript" src="http://www.w3school.com.cn/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#box a").mouseover(function(){
$(this).css("border","1px solid red");
});
$("#box a").mouseout(function(){
$(this).css("border","none");
});
});
</script>
<style>
#box a{ display:block; z-index:1000; width:98px; height:98px;}
</style>
</head>
<body>
<div id="box" style="width:100px; height:100px;">
<a href="#"><img src="erwm.png" border="0" width="99" height="99"/></a>
<a href="#"><img src="erwm.png" border="0" width="99" height="99"/></a>
</div>
</body>
</html>
修改后的正确设计思路：红色部分为调整后的设置
复制代码 代码如下:
<html>
<head>
<script type="text/javascript" src="http://www.w3school.com.cn/jquery/jquery.js"></script>
<script type="text/javascript">
$(document).ready(function(){
$("#box img").mouseover(function(){
$(this).css("border","1px solid red");
});
$("#box img").mouseout(function(){
$(this).css("border","none");
});
});
</script>
<style>
#box a{ display:block; z-index:1000; width:98px; height:98px;}
</style>
</head>
<body>
<div id="box" style="width:100px; height:100px;">
<a href="#"><img src="erwm.png" border="0" width="99" height="99"/></a>
<a href="#"><img src="erwm.png" border="0" width="99" height="99"/></a>
</div>
</body>
</html>
