PHP触发器JS然后返回数据到PHP

Question

我有一个团队电子邮件表单，它只使用名称匹配发件人和接收者的电子邮件。我想添加一个js提示，以便不在列表中的人可以使用他们的电子邮件发送消息。这里就是我有

else { 
    echo "<script type='text/javascript'>prompt('$otheremail');</script>"; 
    $otheremail = file_get_contents("otheremail.json"); 

    #$otheremail=$_POST['data']; 
    $findat2= '@'; 
    $pos2=strpos($otheremail, $findat2); 
    while ($pos2 == false) { 
     $pos2 = 'enter a valid email'; 
     echo "<script type='text/javascript'>prompt('$pos2' , '');</script>"; 
    } 
} 
mail($toaddress, $subject, $message, $headers); 
$success=htmlspecialchars($_GET['to']); 
$success=ucwords($success); 
$valid= 'sent to' . ' ' . $success . ' ' . 'from a php server. Hit the back arrow' ; 
echo "<script type='text/javascript'>alert('$valid');</script>";

应通过jquery's ajax来实现，因为PHP是在服务器端它始终是之前的JavaScript执行的执行，所以你不能这样做很容易。 这里是我的建议（无ajax）：

1. 创建一个新的页面（p1.php），发送给mail.php，简单地接收电子邮件 参数（以从，消息，...）中邮寄或发送 电子邮件;
2. 仅将当前页面用作表单来获取值并设置您的表单，然后以该形式显示用户选择要发送的电子邮件的输入。

下面是如何使用ajax，这是JavaScript的：

这可以通过一个按钮单击或其他事件触发的功能...

<script> 
    function send_mail(to_email, message, headers){ 
     var from_email = prompt("Where from?"); 

     var form_data = {from:from_email ,to:to_email, message, headers};//add your own data 

     $.ajax({ 
      url : "send-email-page.php", 
      type: "POST", 
      data : form_data , 
      success: function(data) 
      { 
       //data is what the send-email-page will echo 
       //it could be a message for the user saying 'email sent' 
      } 
     }); 
    } 
</script> 

而且你可以有一些像这样在你的php页面：

<a href = "javascript: send_mail(<?php echo "$to,$message,$headers";?>)">Send from another address</a> 

---

再次

，如果包括JS在PHP中的JS将被打印到HTML，但它不会被所有的PHP代码有

也许会执行，直到：

编辑我的回答后最好为你评估一下是否有一个有效的名字，如果没有，打印一个带有输入的新表单，询问另一个名字，当这个表单被引用时，它再次调用它自己（php页面） GET参数除用户插入的新名称外，这种方式一直持续询问有效的电子邮件/姓名，直到您拥有一个有效的电子邮件/姓名，如果姓名有效，则只需发送电子邮件并不打印表格。
