let username = "z",
password = "1",
account = 10000,
isLogin = false;
while (!isLogin) {
let usernameInput = window.prompt("请输入用户名:");
let passwordInput = window.prompt("请输入密码:");
console.log(usernameInput, passwordInput)
if (usernameInput === username && password === passwordInput) {
let flag = true;
while (flag) {
let option = ~~window.prompt("选择操作类型: 1. 查询 2. 存款 3. 取款 4. 修改密码 5. 退出 6. 退出登录");
switch (option) {
case 1:
console.log("你的余额为: " + account);
break;
case 2:
{
let money = ~~window.prompt("输入存款金额: ");
account += money;
}
break;
case 3:
{
let money = ~~window.prompt("输入取款金额: ");
account -= money;
}
break;
case 4:
password = window.prompt("输入新密码: ");
break;
case 5:
