Menu
I have problem with jQuery change connected with select tag. It fire twice, second time returning empty array. jQuery or JS is NOT included twice, already checked.
I would be very grateful for any help in this area :)
JS
$(".select-car").on("change", function(){
var cars = [];
var carType = $(this).val();
$.getJSON("js/cars.json", function(data) {
$.each(data, function(i, item) {
// console.log(item);
if(item.type === carType) {
cars.push(item);
}
});
});
console.log(cars);
});

You have two classes .select-car
<div class="row select-car">
and in
<select name="cartype" class="form-control select-car">
Which is causing this to be called twice. And hence binded the change event twice.
