如果登录名不在本地存储中,如何重定向页面?

var storeS = localStorage.getItem("users");
if (storeS == null) {
  var users = [{
    username: "test",
    password: "1234"
  }];
  localStorage.setItem("users", JSON.stringify(users));
}

function getUserUsername(username) {
  return JSON.parse(localStorage.getItem('users')).filter(users => users.username === username)
}

function cheklog() {
  var login = localStorage.getItem("login");
  if (login != null && login == "true") {
    document.querySelector(".wendyloginwrap").classList.add("hidden");
  }
}
cheklog();

function startlog() {
  var username = document.querySelector("#username").value;
  var password = document.querySelector("#password").value;

  if (getUserUsername(username.trim()).length > 0) {
    var user = getUserUsername(username.trim())[0];
    if (user.password == password.trim()) {
      document.querySelector("#login-area").classList.add("hidden");
      document.querySelector("#login-true").classList.remove("hidden");
      localStorage.setItem("login", "true");
      setTimeout(function() {
        window.location.href = "#";
      }, 2000);
    } else {
      document.querySelector("#akses").innerHTML = "username or password is invalid!";
    }
  } else {
    document.querySelector("#akses").innerHTML = "username not found";
  }
}

const show = () => {
  var password = document.querySelector("#password");
  var sandi = document.querySelector(".icon1");
  var sandidua = document.querySelector(".icon2");
  if (password.type === "password") {
    password.type = "text";
    sandidua.style.opacity = "1";
    sandi.style.opacity = "0";
  } else {
    password.type = "password";
    sandidua.style.opacity = "0";
    sandi.style.opacity = "1";
  }
}
