ajax a href onclick获取php变量并执行php文件

Question

我的删除页面代码（delete.php）

    <h4>Select an Article to Delete:</h4>

    <?php foreach ($articles as $article) { ?>

        <span><?php echo $article['article_title']; ?></span> <a href="#" id="link">Delete</a><br />

        <script type="text/javascript">
        $(function(){
            $('#link').click(function(){
                var id = <?php echo $article['article_id']; ?>;
                $.ajax({
                    type: "GET",
                    url: "deleteAtc.php",
                    data: "id"+id+,
                    sucess: function() {
                        $('#sucess').html(data);
                    }
                })
                return false;
            });
        });
        </script>
        <div id="success"></div><br />
    <?php } ?>

虽然我的deleteAtc.php代码是：

<?php

session_start();

include_once('../includes/connection.php');

if (isset($_SESSION['logged_in'])) {
    if (isset($_GET['id'])) {
        $id = $_GET['id'];

        $query = $pdo->prepare('DELETE FROM articles WHERE article_id = ?');
        $query->bindValue(1, $id);
        $query->execute();

        echo "Article deleted";
    }
}    
?>

我在这里想要做的是删除记录而不重定向到deleteAtc.php，它将删除记录并替换Article Deleted

我可以知道我在ajax方面出了什么问题吗？

请参考下面的更新问题

根据以下答案，这是我的更新代码：

delete.php

<h4>Select an Article to Delete:</h4>

<div id="message"></div>

<?php foreach ($articles as $article) { ?>

<span><?php echo $article['article_title']; ?></span> 
<a href="#" class="link" data-artid="<?php echo $article['article_id']; ?>">Delete</a><br />
<?php } ?>

脚本

<script type="text/javascript">
        $(function(){
            $('.link').click(function(){
                var elem = $(this);
                $.ajax({
                    type: "GET",
                    url: "deleteAtc.php",
                    data: "id="+elem.attr('data-artid'),
                    dataType:"json",  
                    success: function(data) {
                        if(data.success){
                               elem.hide();
                               $('#message').html(data.message);
                        }
                    }
                });
                return false;
            });
        });
        </script>

deleteAtc.php

<?php

session_start();

include_once('../includes/connection.php');

if (isset($_SESSION['logged_in'])) {
    if (isset($_GET['id'])) {
        $id = $_GET['id'];

        $query = $pdo->prepare('DELETE FROM articles WHERE article_id = ?');
        $query->bindValue(1, $id);
        $query->execute();

        //Also try to handle false conditions or failure
        echo json_encode(array('success'=>TRUE,'message'=>"Article deleted"));
    }
}    
?>

以某种方式，如果我一次删除两个记录，则只有第一个记录会回显结果，而删除的第二个结果不会回显该结果。

想知道是否可以将jQuery动画添加到.show成功消息和.hide删除记录中？

首先，所有ID均不应重复，而应使用类选择器。您也可以使用自定义数据属性来存储文章的ID。

尝试

<h4>Select an Article to Delete:</h4>

<div id="message"></div>

<?php foreach ($articles as $article) { ?>

<span><?php echo $article['article_title']; ?></span> 
<a href="#" class="link" data-artid="<?php echo $article['article_id']; ?>">Delete</a><br />
<?php } ?>

脚本

<script type="text/javascript">
        $(function(){
            $('.link').click(function(){
                var elem = $(this);
                $.ajax({
                    type: "GET",
                    url: "deleteAtc.php",
                    data: "id="+elem.attr('data-artid'),
                    dataType:"json",  
                    success: function(data) {
                        if(data.success){
                               elem.hide();
                               $('#message').html(data.message);
                        }
                    }
                });
                return false;
            });
        });
        </script>

而在服务器端

<?php

session_start();

include_once('../includes/connection.php');

if (isset($_SESSION['logged_in'])) {
    if (isset($_GET['id'])) {
        $id = $_GET['id'];

        $query = $pdo->prepare('DELETE FROM articles WHERE article_id = ?');
        $query->bindValue(1, $id);
        $query->execute();

        //Also try to handle false conditions or failure
        echo json_encode(array('success'=>TRUE,'message'=>"Article deleted"));
    }
}    
?>
