Js local user entry [duplicate]

I was trying to make a user entry in local and write this code but always “else”
working even if i write correct info. Can you help me with making this code working ?

var email1 = "[email protected]";
var password1 = "1234";

var eposta = document.getElementById("email");
var sifre = document.getElementById("pass");

function login() {
    if (eposta == email1 && sifre == password1) {
    window.location.href = "products.html";
    alert("Welcome", email1);
    }
    else {
        alert("Wrong e-mail or password")
    }
}
