在规则的时间间隔内重新加载div的内容

我想在定期的时间间隔后重新加载div(Recent_updates)的内容。 我使用了以下javascript代码

var refreshId = setInterval(function() { $('#Recent_updates').fadeOut("slow").load('Recent_updates.php').fadeIn("slow"); }, 60000); 

Recent_updates.php

  
sql = "select * from recent_updates where status='Active' and picture1!='' and selling_method!='want_it_now' and selling_method!='ads' and bid_starting_date =now() order by item_id desc"; // sql statement $online_paginate->rows_on_page = $item_no; $results = $online_paginate->get_page_result(); // result set $num_rows = $online_paginate->get_page_num_rows(); // number of records in result set $nav_links = $online_paginate->navigation("  |  "); // the navigation links (define a CSS class ?>
0) { while ($bestsellers_fetch = mysql_fetch_array($results)) { $temp = $bestsellers_fetch['item_id']; $sql = "SELECT count(`user_id`) as response FROM `watch_list` where `item_id`=$temp group by `item_id`"; $res = mysql_query($sql); $response = mysql_fetch_row($res); $counttop = $counttop + 1; if (!empty($bestsellers_fetch['sub_title'])) $item_subtitle1 = $bestsellers_fetch['sub_title']; else $item_subtitle1 = substr($bestsellers_fetch['item_title'], 0, 20); $item_title1 = substr($bestsellers_fetch['item_title'], 0, 40) ?>

除IE之外,此代码在所有浏览器中运行良好。 当我转到我的ie9上的页面并且在几(5-8)分钟后没有做任何事情时,页面就会变成空白。

我已经通过这个…实际上加载失败,因为IE严格validation返回的HTML。 所以确保Recent_updates.php返回有效的html

我不确定IE9但我在旧版本的IE中遇到过这种类型的问题。 该浏览器具有打开与服务器的持久连接的坏习惯,并且大多数服务器(如果不是全部)对每个用户的打开连接数量有限制。 知道你有1分钟的间隔,并且在5分钟后持续连接超时,只需数数,你就会明白为什么……
