昨天朋友让我帮着做个图片高亮展示的效果，虽然不难，不过满有创意的：

<style type="text/css">
*{}{margin:0; padding:0;}
a img{}{border:none;}
#imagesBox {}{ width:165px; height:110px; position:relative; left:100px; top:100px; z-index:1; border:1px solid black; background-color:white;}

</style>
<script type="text/javascript">
  function gallery(obj){
    var tit=obj.getAttribute("alt");  
    document.getElementById("show_tit").firstChild.nodeValue=tit;
    document.getElementById("trans").style.display='block';
    obj.style.zIndex="3";
  }
  function clearBg(obj){
    document.getElementById("show_tit").firstChild.nodeValue="";
    document.getElementById("trans").style.display='none';
    obj.style.zIndex="1";
  }
</script>
</head>
<body>
<div id="imagesBox"> 
  <ul>
  <li><a href="#" title="名称1"><img onmouseover="gallery(this);" onmouseout="clearBg(this)" src="/images/artist//12053006018793_3.jpg" height="55" width="55" alt="名称1"/><span></span></a></li>
  <li><a href="#" title="名称2"><img onmouseover="gallery(this);" onmouseout="clearBg(this)" src="/images/artist//12053006018793_3.jpg" height="55" width="55" alt="名称2"/><span></span></a></li>

  <li><a href="#" title="名称4"><img onmouseover="gallery(this);" onmouseout="clearBg(this)" src="/images/artist//12053006018793_3.jpg" height="55" width="55" alt="名称4"/><span></span></a></li>
  <li><a href="#" title="名称5"><img onmouseover="gallery(this);" onmouseout="clearBg(this)" src="/images/artist//12053006018793_3.jpg" height="55" width="55" alt="名称5"/><span></span></a></li>
  <li><a href="#" title="名称6"><img onmouseover="gallery(this);" onmouseout="clearBg(this)" src="/images/artist//12053006018793_3.jpg" height="55" width="55" alt="名称6"/><span></span></a></li>
 </ul>
<div id="trans">&nbsp;</div>
<strong id="show_tit">&nbsp;</strong>
</div>
</body>
</html>

刚开始因为没有完全明白设计意图，阴差阳错的做了个这样的效果：

<!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>name</title>
<style type="text/css">
*{margin:0; padding:0;}
a img{border:none;}
#imagesBox { width:165px; height:100px; position:relative; left:100px; top:100px;}
#imagesBox li { width:55px; height:55px; float:left; overflow:hidden; position:relative;}
#imagesBox li img { width:55px; height:55px; position:relative; z-index:2; }
#imagesBox li span { line-height:100px; background:#000; position:absolute; top:0; left:0; z-index:3; opacity:0.5; filter:alpha(opacity=50); 
display:block; width:55px; height:55px;}
#imagesBox li a:hover span{display:none;} 
#imagesBox strong{position:absolute;left:0; top:50%; margin-top:-7px; z-index:999; display:block; color:white; width:100%; height:15px; text-
align:center;} 
</style>
<script type="text/javascript">
  function gallery(obj){
    var tit=obj.getAttribute("title");  
    document.getElementById("show_tit").firstChild.nodeValue=tit;
    document.getElementById("imagesBox").onmouseout=function(){document.getElementById("show_tit").firstChild.nodeValue="这里显示
名字"};
  }
</script>
</head>
<body>
<div id="imagesBox">
 <ul>
  <li><a href="#" onmouseover="gallery(this);" title="名称1"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称1"/><span></span></a></li>
  <li><a href="#" onmouseover="gallery(this);" title="名称2"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称2"/><span></span></a></li>
  <li><a href="#" onmouseover="gallery(this);" title="名称3"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称3"/><span></span></a></li>
  <li><a href="#" onmouseover="gallery(this);" title="名称4"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称4"/><span></span></a></li>
  <li><a href="#" onmouseover="gallery(this);" title="名称5"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称5"/><span></span></a></li>
  <li><a href="#" onmouseover="gallery(this);" title="名称6"><img src="/images/artist//12053006018793_3.jpg" height="55" 
width="55" alt="名称6"/><span></span></a></li>
 </ul>
 <strong id="show_tit">这里显示名字</strong>
</div>
</body>
</html>

希望本文所述对大家JavaScript程序设计有所帮助。
