我正在从数据库中提取记录，并在使用php和ajax的gruops中显示它们。PHP：使用Ajax无法正常工作
下面的脚本（找到某处）几乎可以工作，但似乎当您在第一页上并单击“下一步”时，您将被带到最后一页。
只有单独单击数字时，分页才是正确的。
如果需要，我可以在PM中提供测试链接。
的index.php：
<script>
$(document).ready(function() {
$("#results").load("pages.php"); //load initial records
//executes code below when user click on pagination links
$("#results").on("click", ".pagination a", function (e){
e.preventDefault();
var page = $(this).attr("data-page"); //get page number from link
$("#results").load("pages.php",{"page":page}, function(){ //get content from PHP page
});
});
});
</script>
<div id="results"></div>
pages.php：
<?php
// continue only if $_POST is set and it is a Ajax request
if (isset($_POST) && isset($_SERVER['HTTP_X_REQUESTED_WITH']) && strtolower($_SERVER['HTTP_X_REQUESTED_WITH']) == 'xmlhttprequest') {
include (realpath(__DIR__ . '/../db.php'));
// Get page number from Ajax POST
if (isset($_POST["page"])) {
$page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH); //filter number
if (!is_numeric($page_number)) {
die('Invalid page number!');
}
}
else {
$page_number = 1; //if there's no page number, set it to 1
}
// get total number of records from database for pagination
$sql = "SELECT * FROM " . $DBtable . " ORDER BY dates DESC";
$rs = $conn->query($sql);
if ($rs === false) {
trigger_error('Wrong SQL: ' . $sql . ' Error: ' . $conn->error, E_USER_ERROR);
}
else {
$get_total_rows = $rs->fetch_row(); //hold total records in variable
}
// break records into pages
$total_pages = ceil($get_total_rows[0]/$item_per_page);
// get starting position to fetch the records
$page_position = (($page_number - 1) * $item_per_page);
// Limit our results within a specified range.
$rs = $conn->prepare("SELECT id, title, description, dates, clicks FROM " . $DBtable . " ORDER BY dates DESC LIMIT $page_position, $item_per_page");
$rs->execute(); //Execute prepared Query
$rs->bind_result($id, $title, $description, $dates, $clicks); //bind variables to prepared statement
echo '<ul class="contents">';
while($rs->fetch()){ //fetch values
echo '<li>';
echo $id. '. <strong>' .$name.'</strong> — '.$description;
echo '</li>';
}
echo '</ul>';
echo '<div align="center">';
/* We call the pagination function here to generate Pagination link for us. */
echo paginate_function($item_per_page, $page_number, $get_total_rows[0], $total_pages);
echo '</div>';
exit;

这是寻呼机的电流解析的HTML：
<ul class="pagination">
<li class="page-item active first"><a class="page-link" href="#">1<span class="sr-only">(current)</span></a></li>
<li class="page-item"><a class="page-link" href="#" data-page="2" title="Page 2">2</a></li>
<li class="page-item"><a class="page-link" href="#" data-page="3" title="Page 3">3</a></li>
<li class="page-item"><a class="page-link" href="#" data-page="4" title="Next">></a></li>
<li class="page-item last"><a class="page-link" href="#" data-page="4" title="Last">»</a></li>
</ul>
发布你的分页html，所以我想法什么你传递下一个和前一个按钮点击 –
