ajax在文件中调用php代码并获得结果

问题描述：

Some code I want to call from ajax is in a separate file.php:

<?php
     session_start();
     $email1 = $_POST['email1'];
    //some code here processing $email1
     $response = 'some text';
?>

This is how I call it from ajax:

$.ajax({ url: 'file.php',
    data: {email1: $("#user_email").val()},
    type: 'post'
       });

I'd like to be able to do something like this after the call to file.php:

 alert($response);

How do I do that?

我想从ajax调用的一些代码位于一个单独的file.php中： p>

 ＆lt;？php 
 session_start（）; 
 $ email1 = $ _POST ['email1']; 
 //这里的一些代码处理$ email1 
 $ response ='some text'; \  n？＆gt; 
  code>  pre> 
 
 这是我从ajax调用它的方式： p> 
 
 
  $ .ajax（{url  ：'file.php'，
 data：{email1：$（“＃user_email”）。val（）}，
 type：'post'
}）; 
  code>  pre> \  n 
 我想在调用file.php之后能够做这样的事情： p> 
 
 
  alert（$ response）; 
   code>  pre> 
 
 我该怎么做？ p> 
  div>

In your PHP you have to echo the $response, and in your JS you have to specify the callback function like so:

$.ajax({ 
    url: 'file.php',
    data: {
        email1: $("#user_email").val()
    },
    type: 'post',
    success: function(data) { 
        alert(data);
    }
});

答

Inside the ajax call, include a success.. ex:

    success: function(data) {
        alert(data);
    },

This will pop an alert up with your response.

Try:

$.ajax({ url: 'file.php',
    data: {email1: $("#user_email").val()},
    type: 'post',
    success: function(data) { 
          alert(data);
    }
 });

Check out the documentation

You also need to echo out the response in your PHP file:

echo $response;

Something like this?

$.ajax({
  type: "POST",
  url: "file.php",
  data: {email1: $("#user_email").val()},
  success: function(data) {
      alert(data); 
  }
});
