var  radio =document.getElementById('newradiobutton')
var radiotrue=0;

for (var i=0; i<radio.length; i++)
             {
             alert(i);
             if (radio[i].checked)
             {
             radiotrue=1;
             }
             }
             alert(radiotrue);
             if (radiotrue==0)
             {
             showgroupfields();
             return false;
             }

even if the user selects radio button the radiotrue value id 0.

document.getEle mentById() gets only one element. To get a list of radio buttons, use document.getEle mentsByName("ra diobuttons").
