我刚学javascript，想实现单击显隐层这个功能
部分代码如下：
<div id="leftpart">
<div id="title" onmousedown="Mevent('top');">最新推荐</div>
<div id="top">dgjabgjbjabjgbabakg</div>
<div id="title1"onmousedown="Mevent('top1')">最新动态</div>
<div id="top1">fsdhjhshshshsrhr</div>
</div>
<script type="text/javascript">
function Mevent(i){
var idd=document.getElementById(i);
alert(i); if (idd.style.display){
idd.style.disply="none";
}
else
{
idd.style.display="block";
}
}
<script/>可无法实现，怎么回事？
