                        type:'post',
                        url:'ajax2.php',
                        data:'username='+username,
                        success:function(msg){
                            alert(msg);
                        }
                    });
                });
            });
        </script>
    </head>
    <body>
        <input type="text" id="username" />
        <hr />
        <input type="button" id="btnok" value="OK" />
