這篇文章主要為大家詳細(xì)介紹了簡(jiǎn)單實(shí)現(xiàn)Ajax無(wú)刷新分頁(yè)效果的代碼，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

Ajax無(wú)刷新分頁(yè)效果，如下代碼實(shí)現(xiàn)

<!doctype html>
<html lang="en">
<head>
 <meta charset="UTF-8">
 <title>Ajax無(wú)刷新分頁(yè)效果</title>

 <script type="text/javascript">
 function showpage(url) {
  var xhr = new XMLHttpRequest();
  xhr.onreadystatechange = function () {
  if (xhr.readyState == 4) {
   document.getElementById("result").innerHTML = xhr.responseText;
  }
  }

  xhr.open('get',url);
  xhr.send(null);
 }

 window.onload = function () {
  showpage('page.php');
 }
 </script>
</head>
<body>
  <h2 style="text-align: center">Ajax無(wú)刷新分頁(yè)效果</h2>
  <div id="result"></div>
</body>
</html>

網(wǎng)上找的分頁(yè)代碼，親測(cè)可用~

以下是我自己做的一個(gè)簡(jiǎn)單分頁(yè)展示

<?php

 header("Content-type:text/html; charset=utf-8");
 $link = mysqli_connect('localhost','root','123','good');
if (!$link)
{
 die("連接錯(cuò)誤: " . mysqli_connect_error());
}

$sql = "SELECT * FROM ecs_category";
$qry = mysqli_query($link,$sql);
$total = mysqli_num_rows($qry);
$per = 10;

$page = pageDivide($total,$per);

$sql = "SELECT cat_id,cat_name FROM category limit $sqlfirst,$shownu";
 $result = mysqli_query($link,$sql);

 //$goods = mysqli_fetch_all($result,MYSQLI_ASSOC);

 //mysqli_free_result($result);

echo <<<eof
 <style type="text/css">
 table{width:500px;margin:auto;border: 1px solid black; border-collapse:collapse;text-align:center;}
 td{border: 1px solid black;}
 </style>
 <table>
  <tr><td>序號(hào)</td><td>商品編號(hào)</td><td>商品類(lèi)型</td></tr>
eof;

 $num = ($page - 1) * $per;
// foreach ($goods as $k => $v) {
 while($goods = mysqli_fetch_assoc($result)){
 echo "<tr>";
 echo "<td>".++$num."</td>";
 echo "<td>$goods[cat_id]</td>";
 echo "<td>$goods[cat_name]</td>";
 echo "</tr>";
 }

 echo "<tr><td colspan='3'>$pagecon</td></tr>";
 echo "</table>";
