show-hide image onmouseover_问答_开发者_运维开发者技术经验分享

I have 3 images on top of each other. The first one is a normal .jpg image, the second a greyscale version and the 3rd is some kind of effect i add with a transparent .png

Now what i want is that, if i move the mouse over those images, the greyscale image is hidden or replaced by another image and afterwards visible again.

The problem here is that i am a js noob, so it's kind of hard for me to find a solution ^^

my code looks something like this:

<html> 
<head>
<style type="text/css">
<!--                                               
ul li{                     
  display: inline-table;
}
.frame{
  position: relative;  
  height: 110px;
  width: 110px;
}  
.frame div{
  position: absolute;
  top:0px;
  left:0px;              
}       
.effect{                                           
  background:url(images/effect.png) no-repeat;
  height:110px;
  width: 110px; 
}  
.image{
  height:100px;
  width:100px;
  border: 1px solid red;
  margin:4px;    
}
.greyscale{ 
  height:100px;
  width:100px;
  border: 1px solid red;
  margin:4px;          
}    
-->
</style>
</head>

  <li>
    <div class="frame">
      <div class="image"><img src="images/pic1.jpg" height="100" width="100"></div>

      <div class="greyscale"><img src="images/grey2.jpg" height="100" width="100"></div>
      <div class="effect">qewrt</div>
    </div>

would be super-awesome if someone can help me out :)

Try this:

.frame:hover .greyscale { display: none; }

Try adding this to you're css:

div.greyscale:hover img { display: none; }

This will hide you're image if you hover over the greyscale div.

Look into this example,

Here I have a big image on the top and 3 images below.

On mouse hover sll 3 images they will replace big one. on mouse out old image will come back
