# Calculate the amount of jQuery

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>

### UPDATE

``````// 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>
