Why this dosen’t works

Question

<button onclick="Func1" id="Boton1"></button>

function Func1() {
var Cuadrado1 = document.getElementById("Boton1");
if(Cuadrado1).pressed {
alert("Hola");

}

Answer 1

In your button onClick you need parenthesis. onclick="Func1()"

In your function Func1, you don't need the if(Cuadrado1).pressed { because that's what the onclick does, fires when clicked.

<button onclick="Func1()" id="Boton1"></button>

function Func1() {
alert("Hola");
}
