var selectedValue = $("input[name=form]:checked").val();

You should do it like this:

var radio = jQuery('input[name="form"]:checked');

You can then retrieve your radio value or other attributes:

var value = radio.val();

It's a good idea to see if any radio is checked before doing that:

if (radio != undefined)
{
    //do what you need to
}

另外，你也可以试试这个 -

    $(".modal-body input[type=radio]").each(function(){
        if (this.checked)
        {
            console.log(this.value+" is checked");
        }
    });
