Remove Cpfs at the bottom of the Javascript page that validates CPF

Question

I am using this script below to validate the CPF that was obtained from here. However, at the end of the form page, it will record the tested Cpfs in the footer. How to remove this function and leave only the validation?

function CPF() {
  "user_strict";

  function r(r) {
    for (
      var t = null, n = 0; 9 > n; ++n) t += r.toString().charAt(n) * (10 - n);
    var i = t % 11;
    return i = 2 > i ? 0 : 11 - i
  }

  function t(r) {
    for (
      var t = null, n = 0; 10 > n; ++n) t += r.toString().charAt(n) * (11 - n);
    var i = t % 11;
    return i = 2 > i ? 0 : 11 - i
  }
  var n = "CPF Inválido",
    i = "CPF Válido";
  this.gera =
    function() {
      for (
        var n = "", i = 0; 9 > i; ++i) n += Math.floor(9 * Math.random()) + "";
      var o = r(n),
        a = n + "-" + o + t(n + "" + o);
      return a
    }, this.valida =
    function(o) {
      for (
        var a = o.replace(/\D/g, ""), u = a.substring(0, 9), f = a.substring(9, 11), v = 0; 10 > v; v++)
        if ("" + u + f == "" + v + v + v + v + v + v + v + v + v + v + v)
          return n;
      var c = r(u),
        e = t(u + "" + c);
      return f.toString() === c.toString() + e.toString() ? i : n
    }
}
var CPF = new CPF();
document.write(CPF.valida("123.456.789-00"));
document.write("<br> Utilizando o proprio gerador da lib<br><br><br>");
for (var i = 0; i < 40; i++) {
  var temp_cpf = CPF.gera();
  document.write(temp_cpf + " = " + CPF.valida(temp_cpf) + "<br>");
}

$("#input").keypress(function() {
  $("#resposta").html(CPF.valida($(this).val()));
});

$("#input").blur(function() {
  $("#resposta").html(CPF.valida($(this).val()));
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="text" id="input" name="input">
<div id="resposta"></div>

Answer 1

Remove the end of the script, that part:

$("#input").keypress(function(){
    $("#resposta").html(CPF.valida($(this).val()));
 });

$("#input").blur(function(){
    $("#resposta").html(CPF.valida($(this).val()));
});
