Calculate the amount of jQuery

[Alberto]

Please help me to meet the following costing condition.

I have a html form. http://codepen.io/anon/pen/zrvzpO

<form> 
<input type="text" id="text-field">
<input type="text" id="check-field">
<p id="summ"></p>
</form>

If in the text field with id='text-field, I have a number of 10 to 15, it is multiplied by 200 (one condition is fulfilled) If I drive between 20 and 30, then multiply by 400, etc.

If in the text field with id= "check-field" I insert a number from 0 to 15, it multiplys by 10 (first condition) If I drive between 50 and 60, then multiply by 200, etc.

And in the field of id summ, the amount of these fields should be considered.

Thank you very much.

Well, I think you can do it.

// Подключаю слушатель к input по его id
$('#text-field').bind('input', function() {
  // Проверяю, входит ли параметр в наш интервал
  if ($(this).val() > 10 && $(this).val() < 15) {
    // Если входит, то вывожу в p произведение параметра на 200
    $("#summ").html($(this).val() * 200);
  }
  else{
       // Иначе, вывожу предупреждающий текст
       $("#summ").html("Input is not >10 and <15. Please change input number");
  }
});

<form>
  <input type="text" id="text-field">
  <input type="text" id="check-field">
  <p id="summ"></p>
</form>
 <script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>

UPDATE

I answer the question from the comments.

// Подключаю слушатель к input по его id
$('#text-field').bind('input', function() {
  $("#summ").html(+($(this).val()) + +($("#check-field").val()));
});
// Подключаю слушатель к input по его id

$('#check-field').bind('input', function() {

$("#summ").html(+($(this).val()) + +($("#text-field").val()));

});

<form>

<input type="text" id="text-field">

<input type="text" id="check-field">

<p id="summ"></p>

</form>

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
