Hi everyone.

i have a form with a date field and a dropdown list.

my intention is to populate the dropdown field automatically with the day chosen from the date picker. it works fine when the fields are not in a collection but doesn't work at all within a collection.

Example :28-03-2017 will populate the dropdown with "Tuesday"

Any help will be greatly appreciated.

$(document).ready(function () {
function findDay() {
var d = new Date($('#Field15').val());
var weekday = new Array(7);
weekday[0]= "Sunday";
weekday[1] = "Monday";
weekday[2] = "Tuesday";
weekday[3] = "Wednesday";
weekday[4] = "Thursday";
weekday[5] = "Friday";
weekday[6] = "Saturday";
var n = weekday[d.getDay()];
$('.dayWeek select').val(n);
$('.dayWeek select').trigger('change');
}
$('.startDate').on('change', 'input', findDay);
});
