explicit way to identify a radiobutton?

as you can see below, i did quite a hack to recognize a radiobutton, is there a explicit way to identify a radiobutton?

Code:

function add_validation(itemname,descriptor,errstr){
    //radiobutton entry point
    if (typeof(this.formobj[itemname].type)=="undefined"){
        var itemobj = this.formobj[itemname][0];
    }
    else {
        var itemobj = this.formobj[itemname];
    }
}

Is this javascript code?

thought I'm in a javascript thread...

The big picture: I'm developing a form validation component with javascript. Within the .asp page which contains the html for the form as well, I create a validator object and add explicitely validations for a specific field. This specification happens through the input item's name. With this approach (maybe betters already though?) I will have to search in the .js file with the item's name to get the input object itself.

Now my doubt: by checking against the type == "undefined" (see code above) I do not feel comfortable to identify a radiobutton group...
