Identify selected checkbox

Question

Good guys I have a page (view) that makes a select of the bank and returns me the registered images for the user select a limit of photos determined by the administrator most wanted to count and show to the user how many photos he can still select, that is, when it selects an image (a checkbox) it subtracts 1 from the limit and vice versa, I will leave the view code for you to understand better

        <div class="tab-content">
                <div class="tab-pane active" id="select">

                    <div class="row">
                    <?php foreach ($for_fotos as $dados) : ?>

        var total = $('input[type=checkbox]:checked').checked;

        if ($('input[type=checkbox]:checked')) {
            //$(this).attr("checked")=="checked"
            selec--;

Answer 1

$('#list :checkbox').change(function(){
    $('#list :checkbox').each(function(){
        if($(this).is(':checked')){
            /** 
            *Faz o que desejar quando o checkbox estiver marcado
            */
        }
    });
});

What he does: whenever a checkbox that is inside the div #list is modified I go through all the checklists and check if it is checked if I do any action.
