Change single-button actions with javascript

Question

Good morning, everyone,

I have a single-page html code where I control the 3 Divs view with show/hide via a menu.

But I would like to use a single button where as each div is displayed it has a different action. Ex:

DIV 1 ativada
function botão() {        
abreHome();
}

DIV 2 ativada
function botão() {        
abreCatalogo();
}

Answer 1

Try something like that

const changeAction = (t) => {

const action = t.getAttribute('data-action')

return actions[action](t)

}

const actions = {
 acaoUm: (t) =>{
 console.log('Acão um');
 t.setAttribute('data-action', 'acaoDois')
 
 
 },
 acaoDois: (t) =>{
  console.log('Acão dois');
 t.setAttribute('data-action', 'acaoUm')
 
 },

}

<div>
<span onclick="changeAction(this)" data-action="acaoUm">
um
</span>

</span>
</div>

Using jQuery you can easily change the label or functionality of a button when an event is triggered (in your case, when the div have the visibility changed, or something).

Follow an example using Bootstrap Collapse:

var banner = $("#banner-message")
var button = $("button")
var colaps = $("#collapseExample")

colaps.on("show.bs.collapse", function(){
  button.html("Abrir link");
  //altere aqui a funcionalidade tb...
})
colaps.on("hide.bs.collapse", function(){
  button.html("Mudar cor");
})
button.on("click", function(){
  banner.addClass("alt")
})

body {
  background: #20262E;
  padding: 20px;
  font-family: Helvetica;
}

#banner-message {
  background: #fff;
  border-radius: 4px;
  padding: 20px;
  font-size: 25px;
  text-align: center;
  transition: all 0.2s;
  margin: 0 auto;
  width: 300px;
}

button {
  background: #0084ff;
  border: none;
  border-radius: 5px;
  padding: 8px 14px;
  font-size: 15px;
  color: #fff;
}

#banner-message.alt {
  background: #0084ff;
  color: #fff;
  margin-top: 40px;
  width: 200px;
}

#banner-message.alt button {
  background: #fff;
  color: #000;
}
