我需要帮助。我有一个选择代码无法在Ajax中正常工作。 我实际上不知道我在哪里弄错了，但是代码不起作用。 这是代码：
<?php
require_once 'config/dbconfig.php';
if (isset($_REQUEST['note_id'])) {
$id = intval($_REQUEST['note_id']);
$query = "SELECT note_id, class, subject, topic, content, author FROM notes WHERE note_id = :id";
$stmt = $pdo->prepare( $query );
$stmt->execute(array(':id'=>$id));
$row=$stmt->fetch(PDO::FETCH_ASSOC);
?>
<div class="card-body">
<div class="col-md-12 mb-4">
<h5 class="text-center"><?php echo $row['class']; ?></h5>
</div>
<div class="row">
<div class="col-md-6 mb-4">
<h5 class="text-center"><?php echo $row['subject']; ?></h5>
</div>
<div class="col-md-6 mb-4">
<h5 class="text-center"><?php echo $row['topic']; ?></h5>
</div>
</div>
<div class="col-md-12 mb-4">
<?php echo $row['content']; ?>
</div>
<div class="row">
<div class="col-md-4 mb-4">
<h5 class="text-center"></h5>
</div>
<div class="col-md-4 mb-4">
<h5 class="text-center"></h5>
</div>
<div class="col-md-4 mb-4">
Created By: <h5 class="text-center"><?php echo $row['author']; ?></h5>
</div>
</div>
</div>
<?php
}
?>
是ajax，它假定将上述选择代码带到父页面。但是不起作用。
以下是ajax代码：
<script>
$(document).ready(function(){
$(document).on('click', '#getUser', function(e){
e.preventDefault();
var uid = $(this).data('note_id'); // it will get id of clicked row
$('#dynamic-content').html(''); // leave it blank before ajax call
$('#modal-loader').show(); // load ajax loader
$.ajax({
url: 'getnotes.php',
type: 'POST',
data: 'note_id='+uid,
dataType: 'html'
})
.done(function(data){
console.log(data);
$('#dynamic-content').html('');
$('#dynamic-content').html(data); // load response
$('#modal-loader').hide(); // hide ajax loader
})
.fail(function(){
$('#dynamic-content').html('<i class="glyphicon glyphicon-info-sign"></i> Something went wrong, Please try again...');
$('#modal-loader').hide();
});
});
});
</script>
通过锚标记调用它的是锚代码： 实际上是在使用foreach循环。
<li><a data-id="<?php echo $row['note_id']?>" href="#1" class="waves-effect" id="getUser"><?php echo $row['topic']?></a>
</li>
当我单击链接时，它可以工作，但不会在父div中显示请求。
答案 0 :(得分：0)
在PHP中，您正在将数据属性添加到锚点。这是data-id。
<a data-id="<?php echo $row['note_id']?>" ...
在客户端脚本中，您得到了错误的数据属性。 data-note_id不存在。我认为您混淆了数据库列名称和您提供的数据属性名称。
var uid = $(this).data('note_id');
应该是：
var uid = $(this).data('id');
答案 1 :(得分：0)
我假设您正在尝试获取属性“ data-id”的值。
