Notification, "Registration Done" message Displayed by clicking on a form button?

Question

How to get the browser, or actually the site to send messages like those issued for you to subscribe to a newsletter from some site. I want this message to appear when I click the sign-up button...

Answer 1

This is the standard method of sending messages via Javascript:

function msg() {
  alert("Botão Clicado!");
}

<button onclick="msg()">Teste</button>

And here I am mounting a simple Modal call via Javascript/jQuery:

function msg() {
  $("#mensagem").addClass('ver');
  setTimeout(function() {$("#mensagem").removeClass('ver'); }, 3000);
}

#mensagem {
  transition: all 0.52s;
  background: #FFF;
  border: #777 solid 1px;
  box-shadow: 1px 1px 5px rgba(0,0,0,.52);
  position: fixed;
  top: -150px;
  width: 50%;
  padding: 25px 0;
  text-align: center;
  left: 25%;
  opacity: 0;
}

#mensagem.ver {
  top: 75px;
  opacity: 1;
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<button onclick="msg()">Teste</button>

<div id="mensagem">Muito Obrigado por sua Mensagem!</div>
