Multiplying date with checkbox price

[pasayev]

Hello,

I have a difference between check in date and checkout date. I want to multiply difference with checkbox price.

For example,

date difference is :3 days
selected checkbox: 43 $
total result: 43 x 3

Here is my code:

Date difference:

———————————————————————-
<div id=’form-total2′></div>
<script>
jQuery(document).ready(function ($) {function treatAsUTC(date) {
var result = new Date(date);
result.setMinutes(result.getMinutes() – result.getTimezoneOffset());
return result;
}

function daysBetween(startDate, endDate) {
var millisecondsPerDay = 24 * 60 * 60 * 1000;
return (treatAsUTC(endDate) – treatAsUTC(startDate)) / millisecondsPerDay;
}

var calculate = function () {

var sDay = $(‘.iphorm_1_39-input-day’).val();
var sMonth = $(‘.iphorm_1_39-input-month’).val();
var sYear = $(‘.iphorm_1_39-input-year’).val();

var eDay = $(‘.iphorm_1_40-input-day’).val();
var eMonth = $(‘.iphorm_1_40-input-month’).val();
var eYear = $(‘.iphorm_1_40-input-year’).val();

if (sDay != ” && sMonth != ” && sYear != ” && eDay != ” && eMonth != ” && eYear != ”) {
var startDate = new Date(sYear, sMonth – 1, sDay);
var endDate = new Date(eYear, eMonth – 1, eDay);

var diff = daysBetween(startDate, endDate);

$(‘#form-total2’).text(‘Day difference: ‘ + diff);
} else {
$(‘#form-total2’).text(”);
}

};

// Calculate on page load
calculate();

// Recalculate when these date fields are changed
$(‘.iphorm_1_39-input-day, .iphorm_1_39-input-month, .iphorm_1_39-input-year, .iphorm_1_40-input-day, .iphorm_1_40-input-month, .iphorm_1_40-input-year’).change(calculate);

});
</script>

Check boxes:
