I have the following input

<input type="checkbox" name="cupon_check" class="cupon_check" attr-num-doc="D00001" attr-sub-tipo="2" value="12848">

and I'm trying to get the vator of 'attr-sub-type in the following way:

$(".cupones_bienvenida_costarica").find(".cupon_check[attr-num-doc='" + nombre_cupon + "']:checked").each(function(index,value){
                    console.log("CUPONES BIENVENIDA");
                    console.log($(this).data("sub-tipo"));
                });

I do it in that way since I must get that value from several input checkboxes that are selected. but it does not work for me.

Thank you very much in advance

The problem is that you are using the function .data of jQuery, this works to extract HTML attributes that begin with "data- " , the attribute that you use is not like that, change it by .attr('attr-sub-tipo') , this function works for any attribute .
