Ajax调用重新加载Div内存泄漏

有什么建议可以让我的问题更好吗?

所以我有HTML和Javascript代码，从一个程序的DB中取出数据，用于实验室分析的统计分析。例如，你有一个电镀槽，比如说铜，你需要找出浓度，你取槽的pH值，然后把它插入程序，它就会保存这个信息。在网页上，它可以直观地显示已记录的内容，下一个添加的时间以及您必须进行更改的时间。

所以我想刷新页面，每三秒显示时间倒计时，直到下一个测试到期，我已经完成了下面的代码，但是有一个内存泄漏，正如你所看到的，我已经尝试了一些事情，试图清除内存，但无论它建立直到页面冻结。有人知道内存泄漏的问题是什么吗?它发生在FF和ie8 +没有测试低于这一点，在chrome没有内存泄漏，但图像闪烁。

让我提前说一下，我知道这个问题太长了，所以我很抱歉，但我不知道该怎么问。我相信你们所有人都能看到，我对编写web代码的理解有限，所以我也为此道歉。我只是想弄明白为什么记忆会不断累积。希望有一种方法可以修复它，通过更改代码或删除或添加一些代码。

加载脚本。

    function UnloadHandler() { 
window.removeEventListener('unload', UnloadHandler, true); 
}
window.addEventListener('unload', UnloadHandler, true);
jQuery(window).unload(function () { $(window).unbind('unload'); });
jQuery.ajaxSetup ({
cache: false
});
loc = window.location.pathname; //  grabs page url.  ''
pathName = loc.substring(49, loc.lastIndexOf('.') + 4); //  parses out url except for htm file name.  ''
var script = jQuery(document).ready(function() {
var test = setInterval(function(){           //  Sets the data refresh cycle at 3 seconds.  ''
 jQuery.get(pathName, function (response) {
var source = $('<div>' + response + '</div>');
jQuery("#GroupData").empty();
(document.getElementById("GroupData")).innerHTML = "";
 jQuery('#GroupData').html(source.find('#GroupData').load());
timing();  UnloadHandler();
eval(script);
});
},3*1000); //  3 equals seconds to refresh the data thriugh Ajax  ''
}); 

HTML是这样的

<div id="GroupInfo">
    <table style="border:0px; border-style:solid; border-color:#FFFFFF; width:902px; height:20px; border-spacing:0px 1px;border-collapse:seperate; padding:0px; vertical-align:0;">
       <tr>
      <td style="background-color:#FFFFFF;color:000000;background-image: url(../Images/Blue-20x20-Button.png); background-size:30px 22px;width:26px; height:21px;"><div style="color:#000000; text-align:center; margin-bottom:-2px;font-weight:bold;"></div></td>

      <td style="background-color:#FFFFFF;color:000000;background-image: url(../Images/Blue-122x20-ButtonTest.png); background-size:147px 22px;width:135px; height:21px;"><div style="color:#000000; text-align:center; margin-bottom:-2px; font-weight:bold;">Test Status</div></td>

                <td style="width:16px;">&nbsp;</td>
          <td style="background-color:#FFFFFF;color:000000;background-image: url(../Images/Blue-122x20-ButtonTest.png); background-size:148px 22px;width:134px; height:21px;"><div style="color:#000000; text-align:center; margin-bottom:-2px; font-weight:bold;">Corrective Action</div></td>
               </tr>
         </table>
</div>
<div id="GroupData" align="center">
<div id="DrawRows">
        <table class="DrawRow">
                <tr>
                  <td class="drawrows"></td>
                </tr>
                 </table>
</div>
<SCRIPT type="text/javascript">[ItemsHTML]</script>    
</div>

还有一件事，你看到<SCRIPT type="text/javascript">[ItemsHTML]</script>我不太确定这是如何工作的，我没有写，我只是负责改变它。[ItemsHTML]以某种方式从程序的DB中提取数据并显示如下所示，以代替[ItemsHTML]所以有一个源文件，它创建了一个名为out文件的网页在out文件中，而不是;

<SCRIPT type="text/javascript">[ItemsHTML]</script>

变成了这个;

<SCRIPT type="text/javascript">DrawRow ("G54.HTM","0","00 Chem/Etch/Gain Calculations","","","","","","","","","42","42");

这不是一个公开发布的网站，所有这些都是通过打开"out"文件并让它在显示器上运行来完成的，这样员工就可以看到制造过程中发生了什么。

计时功能显示页面的更新时间。显示最后的更改。它还显示当前时间

    function timing(){          //  Function for setting time formats for Current and Updated Time  ''
    var mydate=new Date()
    var Time = "Current Time:  ";
    var Text = "Last Updated:  ";
    var build = Date.parse('[LastBuild]');
    var build2 = dateFormat(build,"dddd m/dd/yy h:MM:ss TT");  //  Format for updated time.  ''
    var build3 = Date.parse(mydate)
    var build4 = dateFormat(build3, "dddd m/dd/yy h:MM:ss TT");
    document.getElementById('time').innerHTML = Time+" "+ build4; //  Sets the current time to chosen format.  ''
    document.getElementById('time2').innerHTML= Text + " " + build2; //  Sets the updated time to format chosen for build2.  ''
}

我也有这个刷新页面每分钟。通过清除大量已分配的内存，这几乎解决了问题，但它并没有释放所有的内存。因此，如果您查看图表上的内存概况，它会上升一分钟，然后下降，但不是在30分钟后一直下降，使用的内存增加了一倍。

function refreshPage() {  //  Sets the page refresh to not scroll in IE  ''
var page_y = document.documentElement.scrollTop;
var page_x = document.documentElement.scrollLeft;
window.location.href = window.location.href.split('?')[0] + '?page_y=' + page_y + "&page_x=" + page_x;
}
window.onload = function () {
timing();
UnloadHandler();

setTimeout(refreshPage, 1*60*1000);  //  Change fist number in equation, the first number represents minutes  ''
var match = window.location.href.split('?')[1].split("&");
if (window.location.href.indexOf('page_y') != -1) {
    document.documentElement.scrollTop = match[0].split("=")[1];
}
if (window.location.href.indexOf('page_x') != -1) {
    document.documentElement.scrollLeft = match[1].split("=")[1];
}
     }
