since your passing data as parameter, you can access the data

try something like this :

var $errors = {};
$errors['success']   = false;
$errors['#errOne']   = "Enter a valid username";
$errors['#errTwo']   = "Enter a valid email";
$errors['#errThree'] = "Enter a valid password";
    data : $errors;
    success: function(data){
    for (var i in data ){
       console.log(i + ':' + data[i]);
    }

可能你需要这个：

success: function(data){
    $.each(data, function(key, value) { 
        alert(key + ': ' + value); 
    });
}

for (var key in data){
   alert(key); // gives keys  success, #errOne, #errTwo, #errThree
   alert(data[key]); // gives values  false, Enter a valid username, Enter a valid email, Enter a valid password
}
