jQuery ajax表单具有json响应

Im having troubles trying to figure out why my JSON data.email response is returning null. Can anyone advise?

我在试图弄明白我的JSON数据的原因时遇到了麻烦。电子邮件回复返回null。谁能建议?

//javascript
$.ajax(
{
 type: 'POST',
 url: 'process.php',
 dataType: 'json',
 data: { email : "[e-mail]" },
 success: function(data)
 {
  alert("result = "+data.email);
 }
});

//php (process.php)
if ($_POST['email']) 
 $return['email'] = $_POST['email'];
else
 $return['email'] = "no email specified";

echo json_encode($return);

whoops, missed the call to json_encode. Still, you need to set the Content-Type of the response to 'application/json' in the php

哎呀，错过了对json_encode的调用。不过，您仍然需要将响应的内容类型设置为php中的“application/json”
