在此页面中没有 jquery 的分页工作

Question

我有一个名为 records.php 的页面，它基本上适用于 ajax 分页，但我希望它在没有 ajax 或任何 js 的情况下也能工作，请有人帮忙，我是新手，真的很棒

我不知道从哪里删除这些代码中的哪些 javascript 代码，以便我可以在这个 php 脚本中进行分页，真的希望这里的一些专家可以帮助我

records.php

您需要将 $_POST['page_id'] 更改为 $_GET['page_id'] 以便可以通过查询字符串发送页码。然后您需要从所有页面链接中删除 onClick 事件。对于 HREF，您必须添加带有 page_id 作为查询变量的页面的 url，并将所需的页面作为它的值。像这样的：

...
...
$page = (int) (isset($_GET['page_id']) ? $_GET['page_id'] : 1);
$page = ($page == 0 ? 1 : $page);
$start = ($page-1) * $records_per_page;

$next = $page + 1;    
$prev = $page - 1;
$last_page = ceil($count/$records_per_page);
$second_last = $last_page - 1; 


$pagination = "";
if($last_page > 1){
    $pagination .= "<div class='pagination'>";
    if($page > 1)
        $pagination.= "<a href='URL_OF_PAGE.php?page=1'  >&laquo; First</a>";
    else
        $pagination.= "<span class='disabled'>&laquo; First</span>";

    if ($page > 1)
        $pagination.= "<a href='URL_OF_PAGE.php?page=<?php echo $prev; ?>'  >&laquo; Previous&nbsp;&nbsp;</a>";
    else
        $pagination.= "<span class='disabled'>&laquo; Previous&nbsp;&nbsp;</span>";   

    if ($last_page < 7 + ($adjacents * 2))
    {   
        for ($counter = 1; $counter <= $last_page; $counter++)
        {
            if ($counter == $page)
                $pagination.= "<span class='current'>$counter</span>";
            else
                $pagination.= "<a href='URL_OF_PAGE.php?page=<?php echo $counter; ?>'>$counter</a>";     

        }
    }
