获取使用AJAX的PHP文件响应 [英] Get response from PHP file using AJAX

问题描述

因此​​，这里是我的问题，我使用AJAX（jQuery的），以张贴形式 process.php 但页面实际需要呼应了回应，如苹果或梅。我不知道如何采取从 process.php 的响应，并将它作为一个变量存储...

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...

这里的code我到目前为止有：

Here's the code I have so far:

<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>

另外，我还需要回响在JSON在 process.php 的反应如何？或者将纯文本被罚款？

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

抱歉，如果这听起来像一个愚蠢的问题，这是我第一次做一些这样的阿贾克斯。

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

PS：您好，我的名字在上面code中的POST请求

PS: How do I name the POST request in the above code?

推荐答案

＆LT;？PHP的回声苹果; ？＆GT; 是pretty的太多字面上你需要的所有服务器上。

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

作为JS端，服务器端脚本的输出作为参数传递给成功处理函数，所以你必须

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
}
