Usually after we share content, a new window will appear to indicate that the sharing was successful, and then a countdown will close the window.

To achieve this effect, we need to write two pages:

First create a page for clicks, open_window.html

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title></title>
</head>
<body>
<a href="javascript:a（）">点击分享至微博</a>
</body>
<script type="text/javascript">
function a（）{
window.open（"new_window.html","_blank","width=500,height=200,top=200,left=300"）；//设置打开新的窗口的大小及位置
}
</script>
</html>

<!DOCTYPE HTML>
<html>
<head>
<title>倒计时自动关闭/跳转页面</title>
<meta charset="utf-8" />
<script>//作业： 改成周期性定时器实现
function myClose（）{//任务
//取出time中的数，保存在n中
var n=parseInt（time.innerHTML）；
n-=1//将n-1
if（n>0）{//如果n>0
//将n+秒钟后自动关闭 再放回time中
time.innerHTML=n+"秒钟后自动关闭";
//再启动下一次定时器，将序号再保存在timer中
timer=setTimeout（arguments.callee,1000）；
}else{//否则
close（）；//关闭
}
}
var timer=null;//保存定时器序号
window.onload=function（）{
timer=setTimeout（myClose,1000）；//启动一次性定时器
}
</script>
</head>
<body style="text-align: center;">
<p style="color: red;font-size: 20px;">（≧▽≦）分享成功！</p><br/><br />
<span id="time">5秒钟后自动关闭</span><br/><br />
