javascript - 警报消息出现问题

Question

当我不输入相同的密码时，我试图让“密码丢失”工作，当没有给出答案时，我尝试让“helo fill everything”工作。

问题是它直接跳过前两个语句，然后跳到最后一个警报“AAAAA”..(对代码的第一部分感到抱歉..)

if(userPassword != userPasswordRepeat)
    {           
        displayAlertMessage(alarm: ("password missing"));
        return
    }
    if(userEmail == "" || userPassword == "" || userFirstName == "" || userLastName == "")
    {
        //vis alarm besked 2
        displayAlertMessage(alarm: ("helo fill everyting"));
        return
    }        

}
func displayAlertMessage(alarm:String)
{
    let myAlert = UIAlertController(title: "Alert", message: "AAAAA", preferredStyle: UIAlertControllerStyle.alert);

    let okAction = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil)


    myAlert.addAction(okAction);


    self.present(myAlert, animated: true, completion: nil)
}
}

使用参数alarm而不是AAAAA

let myAlert = UIAlertController(title: "Alert", message: alarm, preferredStyle: UIAlertControllerStyle.alert);
