我想用javascript更改类的css属性.我真正想要的是当div被悬停时,另一个div应该变得可见.

我的css就像..

.left, .right{
    margin:10px;
    float:left;
    border:1px solid red;
    height:60px;
    width:60px
}
.left:hover, .right:hover{
    border:1px solid blue;
}

.center{
    float:left;
    height:60px;
    width:160px
}

.center .left1, .center .right1{
    margin:10px;
    float:left;
    border:1px solid green;
    height:60px;
    width:58px;
    display:none;
}

而且html文件就像..

<div class="left">
    Hello
</div>
<div class="center">
       <div class="left1">
           Bye
    </div>
       <div class="right1">
           Bye1
    </div>    
</div>
<div class="right">
    Hello2
</div>

当hello1 div悬停时,bye1 div应该是可见的,当hello2悬停时,类似的bye2应该出现.

数组就像......

array ( 
      [0] => a
      [1] => b
      [2] => c
      [3] => d
      [4] => e
      [5] => f
      [6] => g
      [7] => h
     )

我想要他们喜欢..

Array 
( [0] => Array ( 
    [0] => a
    [1] => b)

  [1] => Array ( 
    [0] => c
    [1] => d) 

  [2] => Array ( 
    [0] => e
    [1] => f)

  [3] => Array ( 
    [0] => g
    [1] => h)
)

我怎样才能做到这一点？有8个值,我希望从这8个值中有4对.我是php的新手,所以我真的不知道php和我搜索谷歌,但无法找到解决方案.
