更改组合框时如何取消选中 jquery 表的复选框？

Question

I have the following question, when I change the value of the combobox, the checkboxes are still marked, with prop the values are unmarked, but this time it does not work, the idea is to reset the marked checkboxes when the value of the checkbox is changed. Regards.

                var cambio = $("#cmbKit").on('change', function () {
                    var checkPoint = !$(this).data('checked');
                    $('#tblCajas input[type="checkbox"]').each(function () {
                        if (checkPoint == true) {
                            $(':checkbox').prop('checked', false);
                            $("input[type='checkbox']").prop('checked', false);
                        } 
                    });
                });

                if (cambio) {
                    selectedBox = 0;

                    $('#divCalculos').hide();
                    $('#btnPlanificar').hide();
                }

As you want to reset every checkbox on change event of combobox, you can use below code -

$("#cmbKit").change(function() {
    $("input[type='checkbox']").prop('checked', false);
});

You shouldn't use any if condition as you are going to reset it after every change event.
Please note that given code will reset all checkboxes on page, add table selector as well in case you have multiple table with different content.
Hope this helps.
