ajax的get方式与php配合验证

$(function(){
$('input').click(function() {
var url = 'process.php';
var sendData = {'username':$('#username').val()};
$.get(url,sendData,function(data){
if(data=='true'){
$('div').html('用户名可以注册');
}else{
$('div').html('用户名不能为admin');
}
});
});
});
</script>
<style>
div{color: red;}
</style>
</head>
<body>
<input type="text" name="username" id="username" />
<input type="button" value="检验" />
<div></div>
</body>
</html>
这是php代码
<?php
header('Content-type:text/html;chartest=utf-8');
// $username = $_POST['username'];
$username = $_GET['username'];
if($username=='admin'){
echo 'false';
}else{
echo 'true';
}
?>
