JS关闭窗口或JS关闭页面的几种代码分享

<script language="javascript">
<!--
function closewin(){
self.opener=null;
self.close();}
function clock(){i=i-1
document.title="本窗口将在"+i+"秒后自动关闭!";
if(i>0)setTimeout("clock();",1000);
else closewin();}
var i=10
clock();
//-->
</script>

<a href="javascript:self.close()" >关闭窗口</a>

第三种：窗口没有提示自动关闭的js代码
<script language=javascript> 
<!-- 
this.window.opener = null; 
window.close(); 
//--> 
</script>

document.write "<script language=javascript>alert('您的留言发送成功，我们看到后及时与您联系！');opener=null;window.close();</script>"

document.write("<script language=""JavaScript"">alert(""您的留言发送成功，我们看到后及时与您联系！"");history.go(-1);</script>")

function CloseWin() //这个不会提示是否关闭浏览器   
{   
window.opener=null;   
//window.opener=top;   
window.open("","_self");

var obj_window = window.open('close.html', '_self');   
obj_window.opener = window;   
obj_window.focus();

}
//关闭IE7不提示
function closeie7(){
window.open('','_top');
window.top.close();
