when you do $('input[id$=9]').is(":checked"), an array of all matched
elements is returned. So you can do this:
var checkedNAItems = $('input[id$=9]').is(":checked");
and that should should get you an array of all elements. from there,
you can loop through them and extract the info you need with .attr
("id") and a substring() for each item.
or you can keep to the jquery goodness and use the each function:
$('input[id$=9]').is(":checked").each(function (notApplicableItem)
{
var idNumber = notApplicableItem.attr("id");
var firstPortion = substr(0,idNumber.length-1);
//do more stuff
});
i'm just typing this out and it's not been tested, so this code'll
prob not work, but you get the idea.
hope that helps!
