PHP+AJAX+JQUERY+JSON返回JSON值是UNDEFINE
index.php ajax部分

 

后台ajax.php


header("cache-control:no-cache,must-revalidate"); 

  header('Content-Type: text/html; charset=gb2312'); 

  $name=$_GET["name"];

  $email=$_GET["email"];

  $date=date( "Y-m-d H:i:s ");

  $message=$_GET["message"];

  $link=mysql_connect("localhost","root",""); 

  mysql_query("set names 'gbk'"); 

  mysql_select_db("liuyan");

  $exec="insert into liuyan (name,email,message,date) values ('$name','$email','$message','$date')"; 

  $a=array('name'=>$name,'email'=>$email,'message'=>$message,'date'=>$date);

  echo json_encode($a);

  mysql_close(); 

?>
get传值没问题后台数据一直没添加到数据库里面求大神们帮下忙

------解决方案--------------------
var json=eval("("+json+")");

 这不对啊,直接:

var json = eval(json);就行了啊,json就是一个对象了。
