Use the method prompt()
to collect data in a pop-up, and alert()
to show something in a pop-up:
var texto = prompt('insira texto aqui');
alert(texto);

In the code below (I didn’t use jQuery) there are two events: one to detect the key at the time the value is entered in the input
, and another to detect the click on "Send".
// Função que mostra o valor do input num alert
function mostrarValor() {
alert(document.getElementById("meu-input").value);
}
// Evento que é executado toda vez que uma tecla for pressionada no input
document.getElementById("meu-input").onkeypress = function(e) {
// 13 é a tecla <ENTER>. Se ela for pressionada, mostrar o valor
if (e.keyCode == 13) {
mostrarValor();
e.preventDefault();
}
}
// Evento que é executado ao clicar no botão de enviar
document.getElementById("meu-submit").onclick = function(e) {
mostrarValor();
e.preventDefault();
}
<form method="get">
<input type="text" id="meu-input" />
<input type="submit" id="meu-submit" value="Enviar" />
</form>
