Select All checkboxes using jQuery

Question

I have the following html code:

Answer 1

Use prop() instead -

$(document).ready(function () {
        $("#ckbCheckAll").click(function () {
            $(".checkBoxClass").each(function(){
                if($(this).prop("checked", true)) {
                    $(this).prop("checked", false);
                } else {
                    $(this).prop("checked", true);
                }                
            });
        });
    });

BUT I like @dmk's much more compact answer and +1'd it
