JS实现图片高亮展示效果实例

前端技术 2023/09/06 JavaScript

本文实例讲述了JS实现图片高亮展示效果的方法。分享给大家供大家参考，具体如下：

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：

<!DOCTYPE html PUBLIC \"-//W3C//DTD XHTML 1.0 Transitional//EN\"

<html xmlns=\"http://www.w3.org/1999/xhtml\">

<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:110px; position:relative; left:100px; top:100px; z-index:1; border:1px solid black; background-color:white;}
#trans{}{ width:165px; height:110px; position:absolute; left:0; top:0; z-index:2; display:none; opacity:0.5; filter:alpha(opacity=50); background-color:black;}
#imagesBox li {}{ width:55px; height:55px; float:left; overflow:hidden;}
#imagesBox li a,#imagesBox li img {}{ width:55px; height:55px; display:block; cursor:pointer;}
#imagesBox li img{}{ position:relative;}
#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; z-index:999;} 
</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3\"><img onmouseover=\"gallery(this);\" onmouseout=\"clearBg(this)\" src=\"/images/artist//12053006018793_3.jpg\" height=\"55\" width=\"55\" alt=\"名称3\"/><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\"> </div>
<strong id=\"show_tit\"> </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\"

  <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>
