这个函数是得到相关颜色的,把背景和你的div颜色比对就可以

1.在第二处放一个div,div中再放一个img,并且这个div是隐藏的,只有鼠标指向时才显示,如:
<div id="c" style="display:none"><img id="i" /></div>2.将第一处的每个数字加两个事件,一个是鼠标指向时,一个是鼠标离开时,如:
<a href="#" onmouseover="a('1.jpg');" onmouseout="b();">1</a>
<a href="#" onmouseover="a('2.jpg');" onmouseout="b();">2</a>
...3.然后定义a,b两个事件,如:
function a(url)
{
//找到包含图片的层
var d = document.getElementById("c");
//显示图片
document.getElementById("i").src = url;
//显示层
d.style.display = "";
}function b()
{
//隐藏层
document.getElementById("c").style.display = "none";
}怎么把这段显示隐藏层代码,添加onmouseover渐现onmouseout渐失的效果?
我是js盲啊。。因为我onmouseover,onmouseout要触发传递参数,如何把这两个功能结合成一个函数啊?然后在onmouseover,onmouseout触发。。
楼主有没有考虑div渐小至隐藏?可以通过改变div(或者clip)的尺寸+overflow:hidden实现
filter:Alpha(style=0,opacity=10)
firefox下用
-moz-opacity:0.1
//设置透明度 function setOpacity(obj, value){ if(document.all){ if(value == 100){ obj.style.filter = ""; }else{ obj.style.filter = "alpha(opacity=" + value + ")"; } }else{ obj.style.opacity =value / 100 ; } } //用setTimeout循环减少透明度 function changeOpacity(obj, startValue, endValue, step, speed){ if(step >= 0 && startValue <= endValue || step <= 0 && startValue >= endValue){ document.body.removeChild(obj); return; } if(!obj) { return; } if(startValue<=0) { document.body.removeChild(obj); return; } setOpacity(obj, startValue); setTimeout(function(){changeOpacity(obj, startValue-step, endValue, step, speed);}, speed); } //设置隐藏速度或显示速度和id function showMsg(id){ var msg =document.getElementById(id); var step = 5, speed = 80; if(msg.style.display=="none") { msg.style.display=""; } changeOpacity(msg, 100, 0, step, speed); } http://www.wearelearn.net/javascript/jsData_12_51/574.html
