循環時如何繼續？

Question

用戶正在輸入他/她的密碼，直到密碼正確為止。 當用戶想要單擊“取消”時，我們會詢問“您確定嗎？” 如果答案是否定的，則再次詢問密碼。

我嘗試再次使用Strat，但它不起作用=（

var password = "username",
    user_password        ,
    checked = true       ,
    user_password = prompt("Enter your password"),
    checked_confirm      ;

label: while(checked){
    if(user_password == password){
        alert("You are successfully logged in");
        break;
    }
    else if(user_password == null){
        checked_confirm =  confirm("Are you sure you want to cancel authorization?");
        if(checked_confirm){
            alert("You have canceled authorization");
            break;
        }
        else{
            continue lable;
        }
    }
    else{
        user_password = prompt("Enter your password");
    }
}

在循環開始時詢問密碼，在你得到密碼之前不要中斷：

 var password = "username", user_password, checked_confirm; while (true) { user_password = prompt("Enter your password"); if (user_password == password) { alert("You are successfully logged in"); break; } else if (user_password == null) { checked_confirm = confirm("Are you sure you want to cancel authorization?"); if (checked_confirm) { alert("You have canceled authorization"); break; } } else { alert("Wrong password"); } }
