学习的知识：

 ajax实现php异步交换数据，但是掌握不是很熟练

php代码

<?php

 

  header('Content-Type: application/json');

  header('Content-Type: text/html;charset=utf-8');

 

  $email = $_GET['email'];

 

  $user = [];

 

  $conn = @mysql_connect("localhost","Test","123456") or die("Failed in connecting database");

  mysql_select_db("Test",$conn);

  mysql_query("set names 'UTF-8'");

  $query = "select * from UserInformation where email = '".$email."'";

  $result = mysql_query($query);

  if (null == ($row = mysql_fetch_array($result))) {

    echo $_GET['callback']."(no such user)";

  } else {

    $user['email'] = $email;

    $user['nickname'] = $row['nickname'];

    $user['portrait'] = $row['portrait'];

    echo $_GET['callback']."(".json_encode($user).")";

  }

 

?>

　　js代码

<script>

    $.ajax({

      url: "http://test.localhost/UserInterfaceForChatroom/UserInformation.php?email=pshuyue@gmail.com",

      type: "GET",

      dataType: 'jsonp',

      //      crossDomain: true,

      success: function (result) {

        //        data = $.parseJSON(result);

        //        alert(data.nickname);

        alert(result.nickname);

      }

    });

  </script>
