How do I make messages in Javascript etc, when a warning appears?

Navigation
-2

I want to know a code that when the person clicks on an OK button to appear a warning: "You are logged in!". If you do not get a warning: "You are not in the system, enter your Access information correctly!".

Would you help me?

This is very relative, there are several ways to do this, it depends on what you are using, whether there is a database with user login and password or if you want to use only JS, jQuery to do that.

Here's a basic example of whether the person logged in or not, using the data name = name123 and password = password123, you can see the result: 

<!DOCTYPE html>
<html>
<head>
 <title>teste</title>
 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script><style>#situacao{width:140px;height:70px;display:flex;justify-content:center;align-items:center;margin-top:40px;font-size:16px;}.logado{background-color:#65ff00;}.nLogado{background-color:#cc1212;}</style></head><body><label>Nome:</label><inputtype="text" name="nome" id="nome">
 <br>
 <label> Senha: </label>
 <input type="password" name="senha" id="senha">
 <br>
 <input type="submit" name="enviar" id="enviar" value="Logar">
 <div id="situacao"></div>
 <script>
  nome = "nome123";
  senha = "senha123";
  $("#enviar").click(function(){
    nomeDigitado = $("#nome").val();
    senhaDigitada = $("#senha").val();
    if(nomeDigitado == nome && senhaDigitada == senha){
     alert("Você está logado!");
     $("#situacao").html("Login com sucesso").addClass("logado");
     
    } else {
     alert("Você não esta no sistema, digite corretamente suas informações de Acesso!");
     $("#situacao").html("Login sem sucesso").addClass("nLogado");
    }
  });
 </script>
</body>
</html>
