我无法使用 ajax 调用从我的 php 脚本中检索 json 字符串数据。

这是我的 ajax 脚本：

 $.ajax({
            type: "POST",
            async: false,
            dataType: "json",
            url: "database/clientpanel/logs/search_call_log.php",
            data: {
                from: from,
                to: to,
                sel: sel
                },
            cache: false,
            success: function(data){
                $("#app_panel").append(data.html);
                $('.inv_date').hide();
            }
        });

这是我的 php 脚本：

<?php

include("../../dbinfo.inc.php");
    $from = $_POST['from'];
    $to = $_POST['to'];
    $sel = $_POST['sel'];
// connect to the database
  $client_id = $_SESSION['clientid'];
  $out = 0;
  $in = 0;
  $ext =0;
  $min = 0;
  $sec = 0;
  $results = array(
  'html' => $html
  );    

  $html = " ";
    if($sel == "all"){
  $query=" select * from call where client='$client_id' ORDER BY date_time DESC";
  $result = $mysqli->query($query);
  }else{
  $query=" select * from tele_panel_call where (client='$client_id' AND date_time BETWEEN '$from' AND '$to') ORDER BY date_time DESC";
  $result = $mysqli->query($query);
  }

                                        while ($row = $result->fetch_object())

                                            $html .=  $duration;

                                    $html .= '</div>';

                                        }

     }else{
     echo "No results to display!";
     }  



$jsonString = json_encode($results);
echo $jsonString;

$mysqli->close();
?>

有人可以告诉我我在这里做错了什么吗？当我检查页面本身时，我的 php 脚本没有任何错误。

为 json 数据输出添加适当的标头也很好（例如在脚本的开头）。

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

至于查询结果，你应该调试它。尝试打印查询并在 Phpmyadmin（或其他数据库管理工具）中运行它
