请问,关于onmouseout关联的问题

function Changeimg(gid,img){

                        var oDiv = top.document.createElement("DIV");
                        oDiv.id = "guajian"+gid;
                        oDiv.style.top = 2;
                        oDiv.style.left = 2;
                        oDiv.style.width = 50;
                        oDiv.style.height = 200;
                        oDiv.style.display = 'block';
      oDiv.style.cursor='move';
      oDiv.style.position='absolute';
                        oDiv.innerHTML="<img src='"+img+"' border=0 title='鼠标拖动可移动位置'>"
                        top.document.body.appendChild(oDiv);
      oDiv.onmousedown = function(){top.drag(this)};


}
用js动态创建的层,要往上面加一些层,出现
上面那段代码里的那个效果不知能不能加
<div id=daohang0 style="display:none;Z-INDEX: 2; left: 750px; WIDTH: 100px; POSITION: absolute; TOP: 300px; HEIGHT: 520px; cursor:move;"    >
<div id=daohangtitle style="display:none;background-color:#408CD9; height:18px; WIDTH: 100px; cursor:move;font-size:12px; color:#fff;padding:5px 0 0 5px;font-weight:600;">导航栏   <a href='javascript:;'  id="1">设置</a></div>
<div id="div1" style="display:none;Z-INDEX: 4; position:relative; left:-20px;  background-color:#ffffff; border:1px solid #000; font-size:12px;"></div>
<DIV title='鼠标拖动可移动位置' id=daohang style='display:none;Z-INDEX: 2;POSITION: absolute;top:22px;'><embed src=""></embed></DIV>
</div>
