I have tried your code in local environment, it is working fine. The reason for 503 error because of the Web server (running the Web site) is currently unable to handle the HTTP request due to a temporary overloading or maintenance of the server. The implication is that this is a temporary condition which will be alleviated after some delay. Some servers in this state may also simply refuse the socket connection, in which case a different error may be generated because the socket creation timed out.
user2511140 : I add this code to show errors.my server is to busy and show error.i changed server and problem solved
我已经在本地环境中尝试过你的代码，它工作正常。503错误的原因是由于Web服务器（运行网站）当前由于服务器临时过载或维护而无法处理HTTP请求。这意味着这是一个暂时的情况，将在一些延迟后得到缓解。一些处于这种状态的服务器也可能简单地拒绝套接字连接，在这种情况下，由于套接字创建超时，可能会产生不同的错误。
user2511140 ：我添加此代码以显示错误。我的服务器正忙并显示错误。我更改了服务器并解决了问题
$.ajax({ url: 'add.php',
type: 'post',
data: {'q': ''},
success: function(output) {
alert(output);},
error: function (request, status, error) {
alert(request.responseText);},
});
}

so i know it is old, but i just solved this problem while working on a wordpress project. I got the same error message, because there was a difference between the Url of the admin-ajax - script, written in the header(www.url.de/admin-ajax.ph) - and the url to load the data from (www.urx.de/ajax.php)
所以我知道它很旧，但我只是在处理 wordpress 项目时解决了这个问题。我收到了相同的错误消息，因为 admin-ajax 的 URL 之间存在差异 - 脚本，写在标题（www.url.de/admin-ajax.ph）中 - 和从中加载数据的 url ( www.urx.de/ajax.php)

I think you should call with http://mysite/gd/add.phpor gd/add.phpURL
我认为你应该用http://mysite/gd/add.php或gd/add.phpURL调用
$.ajax({ url: 'http://mysite/gd/add.php',
data: {'q': ''},
type: 'post',
success: function(output) {
alert(output);}
});
If above code is not working. Please check your .htaccessfile.
如果上面的代码不起作用。请检查您的.htaccess文件。

Your current page is a.phpand you send ajax request to add.php, so check whether they both are in same directory or not?
您当前的页面是a.php并且您将ajax请求发送到add.php，因此请检查它们是否在同一目录中？
If so then try following or else try absolute HTTP path.
如果是这样，请尝试遵循或尝试绝对 HTTP 路径。
$.ajax({ url: './add.php',
data: {'q': ''},
type: 'POST',
success: function(output) {
alert(output);
}
});
