It looks like you are confusing the input parameters "name" and "id." They are different. ID is part of the DOM and has nothing to do with forms specifically. You can't get the id value from a form when it's submitted to CF, only the name. That's what form.fieldNames consists of, names.
I'm also a little confused as to whether you are talking about checkboxes or radio buttons. Radio buttons can only have one selection per named group, whereas checkboxes allow multiple selections within a group. Getting at them via cfml is simple. If the name of your checkbox group is "myGroup" for instance, you would simply read #form.myGroup# on your cfm page the form is submitted to. The value of form.myGroup will be a comma delimited list of the values of each checked checkbox. So as an example your form page might have four checkboxes in the myGroup group: checkbox #1: value=a checked=true checkbox #2: value=b checked=false checkbox #3: value=c checked=true checkbox #4: value=d checked=true the value of form.myGroup would be: a,c,d If all you want to do is get the values using CF there's no need for javascript at all. Does that help or am I missing the question here?
