JavaScript特效源码(4、鼠标特效)

1、鼠标感应--渐现特效

　
鼠标感应渐显图片[平时很模糊的图片鼠标一放上就显示清楚]
[修改图片名称即可][共2步]

====1、将以下代码加入HTML的<head></head>之间：

<script language="JavaScript1.2">
function makevisible(cur,which){
if (which==0)
cur.filters.alpha.opacity=100
else
cur.filters.alpha.opacity=20
}
</script>

====2、将以下代码加入到HTML的<body><body>之间：

<img src="想要显示的图片.gif" style="filter:alpha(opacity=20)" onMouseOver="makevisible(this,0)" onMouseOut="makevisible(this,1)">

2、鼠标感应--弹出警告框

　
鼠标感应-弹出警告框[修改文字即可][共1步]
[其实这个效果也没有多大用处，但在个别地方放上一个也能增色不少！^-^]

====1、将以下代码加入到HTML的<body></body>之间：

<a href onmouseover="alert('^-^哈哈上当了，其实什么都没有！')">想听笑话吗？</a>  

3、跟随鼠标的* 特效

　
跟随鼠标的*[推荐][共2步][无须修改]
[顺便告诉你并不一定非用*发挥你的想象改吧！不过好象还是*比较漂亮！]

layerStyleRef="layer.";
layerRef="document.layers";
styleSwitch="";
}
else
