要实现无刷新页面我们一般会用到ajax来实现，以前是使用最原始的js ajax验证现在常用的jquery ajax了只要简单的一句post即可解决了，下面我们看实例

index.php页面

代码如下

复制代码

php jquery check username ajax检查帐号唯一性

jQuery.ajax({
   type: "POST",
   url: "check.php",
   data: 'username='+ username,
   cache: false,
   success: function(response){
if(response == 1){
//不可以注册
$('#username').css('border', '3px #C33 solid');
$('#tick').hide();
$('#cross').fadeIn();
}else{
$('#username').css('border', '3px #090 solid');
$('#cross').hide();
$('#tick').fadeIn();
      }

}
});
}

}

#tick{display:none}
#cross{display:none}

php验证页面，此页面接收到jquery ajax post过来的数据进行验证并返回值

代码如下

复制代码

# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_lr = "localhost";
$database_lr = "ordersiliconebracelets";
$username_lr = "root";
$password_lr = "";
$lr = mysql_pconnect($hostname_lr, $username_lr, $password_lr) or trigger_error(mysql_error(),E_USER_ERROR);
mysql_query("set names utf8;");
//if ($lr) {
//echo "非常好,MYSQL连接成功了!";
//} else {
//echo "不好意思,失败了！";
//}
mysql_select_db($database_lr, $lr);

//
$username = trim(strtolower($_POST['username']));
$username = mysql_escape_string($username);

if (eregi("^[_.0-9a-z-]+@([0-9a-z][0-9a-z-]+.)+[a-z]{2,3}$",$username)) {
//email通过检查
$query = "SELECT email FROM user WHERE email = '$username' LIMIT 1";
$result = mysql_query( $query );
$num = mysql_num_rows($result);

echo $num;
}
else

{
echo "1";//不能注册

}
?>
