I don't know what the problem is, if the link with the button works.

the problem is in line 9 of the code js


html codigo

<!DOCTYPE html>
<html lang="en" dir="ltr">
  <head>
    <meta charset="utf-8">
    <title>cajero ero</title>
  </head>
  <body>
<p>
<img src="cajero.gif" alt="">
</p>
<input type="text" name=""  id="dinero">
<input type="button" name="cosa" value="extraer" id="cosaa">
<script type="text/javascript" src="cajero.js"></script>
  </body>
</html>


js

class Billete {// constructor de billeres nombre y cantidad
    constructor(v,c){
      this.valor=v; //valor del billete
      this.cantidad=c;//cantidad de billetes
    }
}

function entregarDinero (){
  var  t=document.getElementById("dinero");
  var dinero= parseInt(t.valor);

  for (var bi of caja ){ // carga cada elemento de la variable caja a bi en cada ciclo
    if (dinero >0){//comprueba que la cantidad pedida sea mayor que 0
      div =Math.floor(dinero /bi.valor); //hace la division y la redondea por debajo
      if (div > bi.cantidad){
        papeles= bi.cantidad;
      }
      else{
        papeles= div;
      entregar.push(new  Billete(bi.valor, papeles) );
      dinero=dinero-(bi.valor*papeles);
      }
    }
  }
  if (dinero > 0){
    console.log("no tengo mas dinero ");
  }
  console.log(entregar);
}

var caja=[];// caja de nuestro cajero automatico Array donde entaran los billetes
var entregar=[];

caja.push (new Billete (50,3));
caja.push (new Billete (20,2));
caja.push (new Billete (10,2));

//caja.push le agrega contenido a la variable caja
// new Billete crea el objeto billete con los parametros
var dinero=2100;
var div=0;
var papeles=0;


var b = document.getElementById('cosaa');
b.addEventListener("click", entregarDinero);


What I have tried:

I have moved the scrip tag of the html and so the connection with the button has worked, but the connection with the text box does not work for me
