Question

我正在尝试在同一页面上弹出消息。

$db->UpdateAddress($_POST['Cnum'],$_POST['Address']);
     echo "Address changed sucssefully";

我尝试使用它来显示弹出窗口，但弹出窗口是空白页。

  $db->UpdateEmail($_POST['Cnum'],$_POST['mail']);
     $message = "E-mail changed sucssefully";
echo "<script type='text/javascript'>alert('$message');</script>";

感谢

我建议您通过javascript代码中的ajax请求更改电子邮件脚本，并使用jQuery Ajax函数在成功回调时发出警告，如下面的代码

jQuery.ajax({
      url: 'update-email.php',
      type: 'GET',
      dataType: 'json',
      data: {param1: 'value1', param2: "value2"},
      complete: function(xhr, textStatus) {
         //called when complete
      },
      success: function(data, textStatus, xhr) {
        //called when successful
        if(data.message){
           alert(message);
        }
      },
      error: function(xhr, textStatus, errorThrown) {
        //called when there is an error
      }
});

在php中你可以通过

将json结果返回给javascript函数

$array = array("message"=>"your email updated successfully");
echo json_encode($array);

我希望我的回答很有用

您可以使用URL中的GET变量重定向到上一页，而不是在处理更改的php脚本中回显。假设你的上一页是user.php，你可以用

之类的东西替换echo语句

header('Location: user.php?email_changed');

然后，在user.php页面中，您可以添加一些代码

if(isset($_GET['email_changed']) echo "...";

在同一页面中弹出窗口（php）
