Js实现关闭网页窗口时不提示，无提示关闭网页，去掉使用windows.close()的确认提示框：
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312">
<title>无提示关闭网页</title>
</head>
<body>
<script language="JavaScript" type="text/javascript">
function Close()
{
//关闭当前窗口
window.open('','_parent','');
window.close();
}
function OpenWin(url)
{
//全屏打开窗口，网址 url
window.open(url,'_blank','fullscreen=1');
Close();
}
</script>
<input type="button" value="关闭" onclick="Close();"/>
</body>
</html>
