<div onmouseover="f_s('div1')" onclick="closeW('div1','335')" style=" position:absolute;background:black; left: 579px; top: 34px; width: 149px; height: 35px;">
点这可以关闭隐藏层
</div>
<div id="div1" style="position:absolute; background:aqua; left: 451px; top: 73px; width: 349px; height: 335px; display:none" onmouseout="closeW('div1','335')">离开此层可以关闭隐藏层</div>
