鼠标移入移出事件改变图片的分辨率的两种方法
人气:0
最近在做一个鼠标移入移出图片事件，有几种方法大家可以试一下
首先是改变分辨率的两种方法，鼠标移入图片和移出图片的分辨率不同
方法一

<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>图片列表：鼠标移入/移出改变图片透明度</title>
<style>
ul,li{margin:0;padding:0;list-style-type:none;}
#imgList{width:700px;overflow:hidden;zoom:1;border:1px solid #333;margin:0 auto;padding:0 0 10px 10px;}
#imgList li{float:left;width:128px;height:128px;border:1px solid #ccc;margin:10px 10px 0 0;}
#imgList li img{float:left;opacity:0.3;cursor:crosshair;filter:alpha(opacity=30);}
#imgList li.current img{opacity:1;filter:alpha(opacity=100);}
</style>
<script>
window.onload = function ()
{
var oLi = document.getElementsByTagName("li");
for (var i = 0; i < oLi.length; i++)
{
oLi[i].onmouseover = function ()
{
this.className = "current"
};
oLi[i].onmouseout = function ()
{
this.className = ""
}
}
}
</script></head>
<body>
<ul id="imgList">
<li><img src="/jscsshttps://img.qb5200.com/download-x/demoimg/201203/kitesky_com_car1.jpg" /></li>
<li><img src="/jscsshttps://img.qb5200.com/download-x/demoimg/201203/kitesky_com_car2.jpg" /></li>
</ul>
</body>
</html>
方法二
<script type="text/javascript">
function makevisible(cur,which){
if (which==0)
cur.filters.alpha.opacity=100
else
cur.filters.alpha.opacity=20
}
</script>
<body>
<img src="../../Content/themes/login/image/JianKong.png" width="200px" style="filter:alpha(opacity=100)" onMouseOver="makevisible(this,1)" onMouseOut="makevisible(this,0)"/>
</body>
还有一种方法是鼠标移入移出图片，改变图片的大小
在<body>标签中加入一下代码即可，鼠标移动到图片时图片向右上变大，离开图片变回原大小
<img src="../../Content/themes/login/image/Jiben.png" width="200px" onmouseover="this.width=230" onmouseout="this.width=200"/>
