本文实例讲述了jQuery实现的感应鼠标悬停图片色彩渐显效果。分享给大家供大家参考。具体实现方法如下:
<!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>
<title>超个性的感应鼠标悬停图片色彩渐显效果</title>
<meta http-equiv=\"content-type\" content=\"text/html;charset=gb2312\">
<!--把下面代码加到<head>与</head>之间-->
<style type=\"text/css\">
ul.gallery {
width: 750px; /*--Adjust width according to your scenario--*/
list-style: none;
margin: 0; padding: 0;
}
ul.gallery li {
float: left;
margin: 10px 0 10px 25px;
padding: 0;
text-align: center;
border: 1px solid #ccc;
-moz-border-radius: 3px; /*--CSS3 Rounded Corners--*/
-khtml-border-radius: 3px; /*--CSS3 Rounded Corners--*/
-webkit-border-radius: 3px; /*--CSS3 Rounded Corners--*/
display: inline; /*--Gimp Fix aka IE6 Fix - Fixes double margin bug--*/
}
ul.gallery li a.thumb {
width: 336px; /*--Width of image--*/
height: 240px; /*--Height of image--*/
border-bottom: 1px solid #ccc;
cursor: pointer;
}
ul.gallery li span { /*--Used to crop image--*/
width: 336px;
height: 240px;
overflow: hidden;
display: block;
}
ul.gallery li a.thumb:hover {
background: #333; /*--Hover effect for browser with js turned off--*/
}
ul.gallery li h2 {
font-weight: normal;
margin: 0;
padding: 10px;
background: #f0f0f0;
border-top: 1px solid #fff; /*--Subtle bevel effect--*/
}
ul.gallery li a {
text-decoration: none;
color: #777;
display: block;
font-size: 140%;
}
</style>
<script type=\"text/javascript\" src=\"/js/jquery-1.4.2.min.js\"></script>
<script type=\"text/javascript\">
$(document).ready(function() {
$(\"ul.gallery li\").hover(function() { //On hover...
var thumbOver = $(this).find(\"img\").attr(\"src\"); //Get image url and assign it to \'thumbOver\'
//Set a background image(thumbOver) on the <a> tag - Set position to bottom
$(this).find(\"a.thumb\").css({\'background\' : \'url(\' + thumbOver + \') no-repeat center bottom\'});
//Animate the image to 0 opacity (fade it out)
$(this).find(\"span\").stop().fadeTo(\'normal\', 0 , function() {
$(this).hide() //Hide the image after fade
});
} , function() { //on hover out...
//Fade the image to full opacity
$(this).find(\"span\").stop().fadeTo(\'normal\', 1).show();
});
});
</script>
</head>
<body>
预览效果时左下角会提示错误,而且看不到效果,刷新一下就可以看到效果了;当然,在实际使用中,不会出现这样的问题。<br>
<!--把下面代码加到<body>与</body>之间-->
<ul class=\"gallery\">
<li>
<a href=\"#\" class=\"thumb\"><span><img src=\"/html/txdm_2/images/20100904/336240.jpg\" alt=\"\"></span></a>
<h2><a href=\"#\">Sunflowa Media</a></h2>
</li>
</ul>
</body>
</html>
希望本文所述对大家的jQuery程序设计有所帮助。
