How to create an event where when the user presses the space key something happens?

For now I have only this bit of code: 

personagemPular.on("keyup",function(){

I wanted to trade this keyup for pressing space. And I’m also using a area text in HTML to receive keyboard entries, as I do to receive from anywhere on the screen?

You can add this event headset to document or window to listen to events on the entire page and search for the property that says the key code.

Example:

window.addEventListener('keyup', function(e) {
  var codigoTecla = e.which || e.keyCode || 0;
  var space = codigoTecla == 32;
  if (space) alert('O space foi pressionado!');
});

Just check if Event.keycode was 32, which is the space.

Click on the example below and press space

$('#teste').keyup(function (e) { 
   var press = e.which || e.keyCode || 0;
   if(press == 32)
   {
      alert('espaço foi pressionado');
   }
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

Digite em mim<input type="text" id="teste"></input>
