响应后 HTML 中附加的未知文本

Question

我一直在尝试实现无限滚动，在 Ajax 成功调用后，当我将结果附加到 HTML 时，它总是给我一个不必要的数字 1在图片中看到我不知道它来自哪里

Pagination.php

<?php
include 'connection.php';

// header('Content-Type: application/json');

$pageno = $_POST['pageno'];

$no_of_records_per_page = 5;
$offset = ($pageno-1) * $no_of_records_per_page;

$sql = "SELECT *, 
  posts.id AS post_id, 
  posts.created_at AS post_created_at 
  FROM posts 
  LEFT JOIN users_account 
  ON posts.user_id = users_account.id 
  LEFT JOIN users_personal_info
  ON users_account.id = users_personal_info.user_id
  ORDER BY post_id DESC LIMIT {$offset}, {$no_of_records_per_page}";
$stmt = $connect->prepare($sql);
$stmt->execute();
$rows = $stmt->fetchAll(PDO::FETCH_OBJ);
$post_count = $stmt->rowCount();
if ($post_count > 0) {
    $results = include('data.php');
    echo $results;
} else {
    echo 'maxed';
}

Index.php

<?php


include 'connection.php'; 

?>
<!DOCTYPE html>
<html lang="en">
<head>
  <?php include 'mda_header.php' ?>
  <style>

  #loader{
      display: block;
      margin: auto;
  }
</style>
</head>
<body>

<div class="container">
    <?php
        $sql = "SELECT *, 
          posts.id AS post_id, 
          posts.created_at AS post_created_at 
          FROM posts 
          LEFT JOIN users_account 
          ON posts.user_id = users_account.id 
          LEFT JOIN users_personal_info
          ON users_account.id = users_personal_info.user_id
          ORDER BY post_id DESC LIMIT 5";
        $stmt = $connect->prepare($sql);
        $stmt->execute(); 
        $rows = $stmt->fetchAll(PDO::FETCH_OBJ);
        ?>
        <?php include 'data.php' ?>
  <div id="response"></div>
</div>
  <input type="hidden" id="pageno" value="1">
  <img id="loader" src="https://i.redd.it/ounq1mw5kdxy.gif">
  <script src="jquery.inview.min.js"></script>
  <script>
    $(document).ready(function(){
      $('#loader').on('inview', function(event, isInView) {
          if (isInView) {
              var nextPage = parseInt($('#pageno').val()) + 1;
              console.log(nextPage);
              var total = parseInt($('#total').val());
              $.ajax({
                  type: 'POST',
                  url: 'pagination.php',
                  data: { pageno: nextPage, total: total },
                  success: function(response){
                    if (response != 'maxed') {
                      $('#response').append(response);
                      $('#pageno').val(nextPage);
                    } else {
                      $('#loader').hide();
                    }
                  }
              });
          }
      });
  }
  </script>
</body>
</html>

这是我获取结果的地方，我在代码中没有看到任何数字

Answer 1

您只需要一个包含 - 您也不需要回显结果，您可能会发现 $results 是 1 以指示 include() 成功。更改

$results = include('data.php');
echo $results;

至

include('data.php');

如果包含的脚本使用 return 传回数据，您只需要赋值和 echo。
