我有一个名为js.php的PHP页面，我想刷新页面而不重新加载整个页面。我知道这个问题已经问了太多次，但我就是不能理解它。我尝试了下面的代码，但它不工作。我还想问，这段代码应该放在. js.php或其他文件的什么地方？？有没有其他方法可以在不重新加载的情况下刷新页面？它相当长，但最终我想刷新页面，特别是2个变量，profittext和sumtext请忽略斜线代码。
js.php

<?php 
//error_reporting(0);//on if need

//require "core/init.php";
//protectpage();
$bidpricepl='';
$offerpricepl='';
$sum='';
$profitText =0;
$sumText=0;
?>

您可以将此代码保存在Js.php中
如果您没有得到想要的结果，t## en您可以使用ctr+shift+j尝试filrebug和chjeck查找任何javascript错误
或者使用iframe。

您的网页中有一个错误，它将阻止脚本工作。

<html>
    <head>
        <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.0/jquery.min.js">

            $(document).ready(function() {
             var reloadData = 0; // store timer

                // ----- load data on page load, which sets timeout to reload again
               loadData();
            });

            function loadData() {
                $('#load_me').load('js.php', function() {
                   if (reloadData != 0)
                       window.clearTimeout(reloadData);
                   reloadData = window.setTimeout(loadData, 1000)
               }).fadeIn("slow"); 
            }

这是因为你 AJAX 请求指向同一个页面。你可以将ajax发送到其他php（test.php）文件在test.php中只生成你想在div中显示的内容

<div id="load_me">
$data
</div>

仅回显$data
和退出。
如果您想创建一个新的函数，请点击这里.

只需使用 AJAX （异步JavaScript和XML）。Click here for more info
如果不刷新整个页面，则无法对页面的特定部分使用PHP
