背景：前不久給一個朋友寫了一個自動刷新頁面數據的demo,修改成html內嵌js 的文件，這樣便於理解，需要引入的插件有jquery 和jquery.cookie.js（用於緩存頁面的用戶數據）
以下是源代碼：
<!DOCTYPE html >
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>autorefresh</title>
<script src="http://apps.bdimg.com/libs/jquery/1.6.4/jquery.js"></script>
<script src=" jquery.cookie.js"></script>
<style>
table, td, tr, th {
font-size: 12px;
}
.list table th {
background-color: #f2f4f6;
border-bottom: 1px solid #c1c8d2;
color: #7d7d7d;
font-weight: normal;
height: 35px;
padding-left: 5px;
/* text-align: left; */
}
.Toolbar_inbox {
background-color: #d2dbea;
border-bottom: 1px solid #c8cfda;
line-height: 26px;
overflow: hidden;
padding: 5px;
}
table, td, tr, th {

}
.so_main {
