这是我的第一页，我想在名为＆＃39; middle div＆＃39;的div中加载名为notification.php的第二页。第一页我的第一页的名字是homepage.php

下面给出的代码是我的notification.php

<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>notification</title>
</head>
<body>
<?php
include "db.php";
 session_start();
 if($_SESSION['login_user']==$_SESSION['mail'])
  {
    $mail=$_SESSION['mail'];

    $query=mysql_query("select notification from notification where email='$mail' order by id desc");

    while($row= mysql_fetch_array($query))
       {  
        echo '<div id="notificationdiv" style="background-color:#CFC; width:100%; height:30px">'.$row['notification'].'</div>'.'<br>'; 
       }

  }
  else
   {
    $lu=$_SESSION['login_user'];
    $query2=mysql_query("select notification from notification where email='$lu' order by id desc");
    while($row2= mysql_fetch_array($query2))
       {  
        echo '<div id="notificationdiv" style="background-color:#CFC; width:900px; height:500px">'.$row2['notification'].'</div>'.'<br>'; 
       }   
   }

?>


</body>
</html>

请帮助我是php和ajax的新手。

Answer 1

在Web浏览器中执行notification.php并在浏览器中检查结果。如果它回显你想要的输出??

Answer 2

由于您标记了JQuery，那么使用JQuery .load()函数进行测试会怎么样。

Answer 3

改变这个：

preg_match_all("/Some\s+text:\s+(?:([A-Z]{2,3})(?:\s+\=(\s\w+)*))(?:\,\s+([A-Z]{2,3})(?:\s+\=(\s\w+)*))*/mi" , $input_lines, $output_array);

由：

<a href="homepage.php" style="font-size:28px; text-decoration:none; margin-left:30px; onClick="clic()">Notification</a>

此外，它应该消除：style =

中的初始引号

在php中编程，使用ajax在旧页面div中加载新页面
