javascript - 为什么这段代码不起作用？ for 和 if 的组合用于 "test"登录页面

Question

我正在尝试制作某种登录页面(我不关心安全性或某种类型。这是一个测试，我什至不是那么高级的编码员。而且我正在努力解决编码。我想将其设为:

    If the username was filled in as "Ardent" and the password as "1", 
        Say something like "Welcome!"
    If the username or(and) the password are(is) incorrect, 
        alert("The username and password is incorrect."); 
and make it loop, leading to asking for username and password again.

所以，这就是我编码的内容(我不知道它是如何工作的，所以我什至不知道它的基本结构)。

for([id == prompt("What is your ID?"), password == prompt("What is your password?")]; 
     id == "Ardent" || password == "1" ;) {

    prompt("What is your ID?");
    prompt("What is your password?");
    if(id == "Ardent" || password == "1") {
        alert("Welcome back!");
    }
}

谢谢!抱歉，如果它实际上是一团糟:(我的编码能力很差，而且我只是个初学者。

您可以从下面非常清晰的代码开始。

while(true){
    var username = prompt("What is your username");
    var password = prompt("What is your password");
  
    if(username == "Ardent" && password == "1"){
  	    alert("Welcome");
        break;
    }
    else{
       alert("Try again");
    }
}

希望有帮助。
