我是php和jQuery的新手，现在我有一个问题;当我使用数据表来查询数据，错误作为标题和详细代码时，如下所示：

HTML：

<!DOCTYPE html>
<html>
    <head>
        <meta charset="GBK">
            <title>作业</title>
            <link href="http://CEA815099W/test/cim_web/css/bootstrap.min.css" rel="stylesheet" type="text/css" />
            <link rel="stylesheet" type="text/css" href="http://Cea815099w/test/cim_web/css/dataTables.bootstrap.css" />
            <script src="http://CEA815099W/test/cim_web/js/jquery-1.11.3.min.js"></script>
            <script src="http://CEA815099W/test/cim_web/js/jquery.dataTables.min.js"></script>
            <script src="http://CEA815099W/test/cim_web/js/dataTables.bootstrap.js"></script>
            <script src="http://CEA815099W/test/cim_web/js/echarts.js"></script>
            <script src="http://CEA815099W/test/cim_web/js/bootstrap.min.js">
    </head>
    <body>
  <!-- table--> 
  <div class="container">
    <table id="example" class="table table-striped table-bordered" cellspacing="0" width="100%">
        <thead>
              <tr>
                  <th>工号</th>
                  <th>班别</th>
          <th>站点</th>
                  <th>时间</th>
              </tr>
          </thead>
          <tbody>
          <!-- js处理数据库内容--> 
          </tbody>
          <tfoot>
              <tr>
                  <th>工号</th>
                  <th>班别</th>
          <th>站点</th>
                  <th>时间</th>
              </tr>
          </tfoot>  
     </table>
  </div>
</body>
</html>

使用Javascript：

$(document).ready(function() {
       $('#example').dataTable( {
           "bProcessing": true,
           "sAjaxSource": "data.php"
       } );
   } );    

</script>
<script type="text/javascript">
    // For demo to fit into DataTables site builder...
    $('#example')
           .removeClass( 'display' );
            .addClass('table table-striped table-bordered');
</script>

PHP：

<?php
$db = new PDO("oci:dbname=mfdm10", "f10mfg",'demon');
$db->setAttribute(PDO::ATTR_ERRMODE,PDO::ERRMODE_WARNING);  // 设置为警告模式
$rs = $db->prepare("select a.empid,a.shift,a.station,a.infab_time from ut_msc_newcoming a where rownum <= :num"); // SQL 需要修改
$rs->bindValue(':num', 26);
$rs->execute();
while($row=$rs->fetch()){       
    $data[]=  array(
        $row[0],
        $row[1],
        $row[2],
        $row[3]
              );
    }

/* $output = array(
        "sEcho" => 1,
        "iTotalRecords" => count($row),
        "iTotalDisplayRecords" => count($row),
        "aaData" => $data
    );  */
    $response = array();
    $response['success'] = true;
    $response['aaData'] = $data;
    echo json_encode( $response );

    //异常
    function fatal($msg)
    {
        echo json_encode(array(
            "error" => $msg
        ));
        exit(0);
    }

?>

我的原始json返回，有任何错误吗？

Answer 1

在this page in the documentation上，它说明了以下内容：

来自服务器的回复

在回复DataTables向服务器发出的每个信息请求时，它希望得到一个结构良好的JSON对象，其中包含以下参数....

您似乎没有设置这些变量，这可能是错误消息的原因＆＃34;警告：table id = example - 无效的JSON响应＆＃34;作为您的JSON，虽然有效的JSON，但不是有效的＆＃34; JSON响应＆＃34;与数据表的期望有关。
