我正在开发一个基于rrdtool的移动友好监控工具。

一切都很好，但当我打开网页超过1小时时，我的电脑就会冻结。

我使用这个片段来刷新图像。

<?php
if(!isset($includeCheck))
{
        exit ("No tienes permisos para ver directamente el archivo");
}
//echo "
//<script language='JavaScript'>
//        function refreshIt(element) {
//                setTimeout(function() {
//                element.src = element.src.split('?')[0] + '?' + new Date().getTime();
//                refreshIt(element);
//              }, 50000); 
//      }
//</script>";
echo "
<script language='JavaScript'>
        function refreshIt(element){
                setInterval(function() {
                element.src = element.src.split('?')[0] + '?' + new Date().getTime();
                }, 50000);
        }
</script>";

?>

我在页面中包含了这个php文件，我有图像，我想刷新。

我尝试了这两个选项，但正如我所说，冻结了我的浏览器。

有人知道我能做什么吗？因为我只需要刷新图像，所以我不想重新构建整个页面。

这是用于打印数据库中所有图像的PHP脚本。
