删除行使用AJAX

Question

我想点击其ID的参考按钮后删除spacific行表的ID，

这里是我的PHP代码，

while($row = mysqli_fetch_array($values)) { 
    echo "<tbody>"; 
    echo "<tr id=\"12\">"; 
    echo "<td>" . $row['pid'] . "</td>"; 
    echo "<td>'<img src='/Login/product_avtar/".$row['pic']."' width=\"80\" height=\"60\">'</td>"; 
    echo "<td>" . $row['pname'] . "</td>"; 
    echo "<td>" . $row['pprice'] . "</td>"; 
    echo "<td>" . $row['pdes'] . "</td>"; 
    echo "<td>" . $row['qnt'] . "</td>"; 
    echo "<td><button class=\"btn btn-sm btn-danger delete_class\" id=\"".$row['pid']."\">Delete</button></td>"; 
    echo "</tr>"; 
    echo "</tbody>"; 

这是阿贾克斯，

$(function() { 
    $(".delete_class").click(function(){ 

    var element = $(this); 
    var del_id = element.attr("pid"); 
    var info = 'pid=' + del_id; 
    if(confirm("Are you sure you want to delete this Record?")){ 
     $.ajax({ 
      type: "POST", 
      url: ajax_url, 
      data: info, 

       success: function(){ 
       alert('Successfully Deleted'); 

      } 
     }); 
    } 
    return false; 
    }); 
}); 

，这是ajax_url，

if(($_POST['pid'])) 
{ 
    $id=$_POST['pid']; 
    $id = mysqli_real_escape_string($id); 

    $option = mysqli_query($conn,"DELETE * FROM product where pid = ".$id.""); 
} 

请帮忙找出解决方案， 感谢

您已经使用属性PID：

var del_id = element.attr("pid"); 

但在HTML中指定的属性是ID，而不是PID。

更改此：

<button class=\"btn btn-sm btn-danger delete_class\" id=\"".$row['pid']."\">Delete</button> 

要这样：

<button class=\"btn btn-sm btn-danger delete_class\" pid=\"".$row['pid']."\">Delete</button> 

并尝试调试在您的jQuery：

var del_id = element.attr("pid"); 
console.log(del_id); // On chrome, go to the Inspect Element > console tab and check if the id retrieved is correct.
