js setTimeout实现延迟关闭弹出层

有时候我们希望弹出层能够实现延迟关闭，并且鼠标在弹出层区域移动的时候能够保持显现，下面是具体的实现代码。

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="SetTimeout.aspx.cs" Inherits="JavaScript.SetTimeout" %> 
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<style type="text/css"> 
#flyout 
{ 
border: solid 2px Gray; 
background-color: #FFF999; 
width: 300px; 
height: 100px; 
display: none; 
} 
</style> 
<script type="text/javascript"> 
var flyoutTimer; 
function mouseOutEvent() { 
//Hide flyout after 1 second when the mouse move out of the flyout zone 
flyoutTimer = setTimeout(hideFlyout, 1000); 
} 
function mouseOverEvent() { 
//Clear the timer when the mouse move over the flyout 
clearTimeout(flyoutTimer); 
} 
function hideFlyout() { 
document.getElementById("flyout").style.display = "none"; 
} 
function showFlyout() { 
document.getElementById("flyout").style.display = "block"; 
mouseOutEvent(); 
} 
</script> 
</head> 
<body> 
<form id="form1" runat="server"> 
<div onclick="showFlyout()"> 
Click me to show flyout</div> 
<div id="flyout" onmouseout="mouseOutEvent()" onmouseover="mouseOverEvent()"> 
This is a flyout 
</div> 
</form> 
</body> 
</html>
