我想让登录按钮在登录账户后消失，但似乎做不到。我试过使用 localStorage 和 sessionStorage，但都没用。我哪里做错了？

登录：

var objPeople = [{
    username: "#",
    password: "#"
  },
  {
    username: "#",
    password: "#"
  },
  {
    username: "test",
    password: "123"
  }
]

function getInfo() {
  var username = document.getElementById("username").value
  var password = document.getElementById("password").value

  for (var i = 0; i < objPeople.length; i++) {
    if (username == objPeople[i].username && password == objPeople[i].password) {
      console.log(username + "is logged in.")
      window.location.href = "homepage.html"
      localStorage.setItem("signedIn", 1);
    }

  }
  console.log("Username/password is incorrect.")
}

const signedInTrue = localStorage.setItem("signedIn")
if (signedInTrue= 1) {
    document.getElementById("topNav").style.display = "block"
}
