Jquery using checkbox to change dropdown by class not name

Question

I want to update all dropdowns by clicking on checkbox. I'm using foreach to get all the selected checkboxes.

This will update all on the page but I want to accomplish this using the class name not the field name

$('select[name=order_status] option[value=1]').attr('selected', 'selected');

I want something like this ".shipping_'+do_csv+'

$('.option_completed').click(function() {
    var do_csv = [];
    $("input[name='options[]']:checked").each(function() {
        do_csv.push($(this).val());
        $(".shipping_'+do_csv+' option[value=1]").attr('selected', 'selected');
    });
});

.shipping_'+do_csv+' gets it value from the checkbox the class could be .shipping_1 or .shipping_3432 depending on the order id — MHowey

replace this:

$(".shipping_'+do_csv+' option[value=1]").attr('selected', 'selected');

with that:

$(".shipping_"+$(this).val()+" option[value=1]").attr('selected', 'selected');

If your class names are shipping_somethinghere and dp_csv is an array of somethinghere's, then I think this is what you're looking for:

$.each(do_csv, function(i, val) {
    $(".shipping_" + val + " option[value=1]").attr('selected', 'selected');
}
