Hello, I have a question, I have 2 input and a select and a clear button. What seo is when the 3 fields are filled (input and select) the button is enabled but remains disabled. I would appreciate your help! Thanks in advance.

Pdt: I'm working with Materialize.css

I'm trying something like this: 

<!DOCTYPE html>
<html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Login</title>
        <link rel="stylesheet" href="css/materialize.min.css">
        <link rel="stylesheet" href="css/style.css">
    </head>
    <body> 
      <div class="materialContainer">
        <div  style="background-color:rgba(208, 208, 208, 0.00);"></div>
          <div class="card">

            <h1 class="title" >&nbsp;&nbsp;&nbsp;
              <img src="img/logo_sesion.png" width="90" style="position:relative; right: 35px; bottom: 30px"/>
            </h1>

            <form name="Login">

              <div class="card-content">
                  <div class="row" style="margin: auto">
                    <div class="input-field col s12">
                        <input id="user_name" type="text" class="validate">
                        <label for="user_name" class="active">Usuario (Email)</label>
                    </div>
                  </div>
                  <div class="row" style="margin: auto">
                    <div class="input-field col s12">
                      <input id="password" type="text" class="validate">
                      <label for="password" class="active">Contraseña</label>
                    </div>
                 </div>
                 <div class="row" style="margin: auto">
                    <div class="input-field col s12">
                      <select id="dominio">
                        <option value="" disabled selected>Seleccionar</option>
                        <option value="1">Option 1</option>

I found a solution to what I asked but it is not quite finished, they will see I need the select and I do not know how to do it if they knew it would be great to share it, Regards! 

$(document).ready(function() {
    $('a[type="submit"]').attr('disabled','disabled');
    $('input[type="text"]').keypress(function(){
      if($("#user_name").val() != '' && $("#password").val() != '') {
        $('a[type="submit"]').removeAttr('disabled');
      }
    });
});

$('#boton').attr("disabled", true);

With that code it should work to disable it. If you want to enable it again, try: 

$('#boton').attr("disabled", false);
