按esc键退出的一个函数

自动关闭窗口
1做一些小窗口发消息的等程序常用到自动关闭窗口
2方法一:
3<OBJECT id=closew type="application/x-oleobject" classid="clsid:adb880a6-d8ff-11cf-9377-00aa003b7a11">
4<param name="Command" value="Close">
5</object>
6<script LANGUAGE="JavaScript">
7<!--
8setTimeout('colosw.Click();', 1000);
9// -->
10</script>
11<%
12response.write"留言成功!"
13
14
15设置1秒留点时间显示 "留言成功!"
16缺点,无发使用与Tencent等一些浏览器，会把整个窗一起关掉
17
18
19方法二
20<script LANGUAGE="JavaScript">
21<!--
22function closew(){
23 self.focus();
24 self.close();
25 return false;
26 }
27
28setTimeout("closew();", 1000);
29// -->

31<%
32response.write"留言成功!"
