循环时如何继续？

Question

用户正在输入他/她的密码，直到密码正确为止。 当用户想要单击“取消”时，我们会询问“您确定吗？” 如果答案是否定的，则再次询问密码。

我尝试再次使用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");
    }
}

在循环开始时询问密码，在你得到密码之前不要中断：

 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"); } }
