问题:当绿色的DIV显示出来后,鼠标移入DIV无事,再移到aaaa正上方的一小部分局域(就aaaa四个字母上方),DIV就关了,不知为何
<div style="margin:0px auto 0px auto; position:absolute;left:250px;top:250px;padding:20px; z-index:1;">
<asp:LinkButton ID="LinkButton1" onmouseover="over(this,document.all.se)" onmouseout="timer=setTimeout('out(document.all.se)',500)" OnClientClick="alert('left'+this.offsetLeft+';top'+this.offsetTop+';高'+this.offsetHeight+';宽'+this.offsetWidth);return false;" runat="server">M我</asp:LinkButton>
</div>
<div id="se" onmouseover="clearTimeout(timer);this.style.display='block'" onmouseout="out(this)" style=" background-color:#32ba5c; display:none; 200px; position:absolute; padding:20px;">
<div >aaaa</div>
<div >bbbb<input type="button" onclick="this.parentElement.parentElement.style.display='none'" value="关闭" /></div>
<div>aaaa</div>
<div>bbbb</div>
<div>aaaa</div>
<div>bbbb</div>
