使用 AJAX 从 PHP 文件获取响应 [英] Get response from PHP file using AJAX

问题描述

所以这是我的问题，我使用 AJAX (jQuery) 将表单发布到 process.php 但页面实际上需要回显响应，例如 apple或 梅花.我不确定如何从 process.php 获取响应并将其存储为变量...

So here's my issue, I am using AJAX (jQuery) to post a form to process.php but the page actually needs to echo out a response such as apple or plum. I'm not sure how to take the response from process.php and have it stored as a variable...

这是我目前的代码:

<script type="text/javascript">
        function returnwasset(){
            alert('return sent');
            $.ajax({
                type: "POST",
                url: "process.php",
                data: somedata;
                success function(){
                    //echo what the server sent back...
                }
            });
        }
    </script>

我还需要在 json 中回显 process.php 中的响应吗?还是纯文本可以?

Also will I need to echo the response in process.php in json? or will plain text be fine?

对不起，如果这听起来像一个愚蠢的问题，这是我第一次在 Ajax 中做这样的事情.

Sorry if this sounds like a stupid question, this is my first time doing something as such in Ajax.

PS:上面代码中的POST请求如何命名?

推荐答案

几乎是您在服务器上所需的全部内容.

<?php echo 'apple'; ?> is pretty much literally all you need on the server.

至于 JS 端，服务器端脚本的输出作为参数传递给成功处理函数，所以你有

as for the JS side, the output of the server-side script is passed as a parameter to the success handler function, so you'd have

success: function(data) {
   alert(data); // apple
}
