    getElementById returns a single element because, even for radio groups, the id attribute must be unique. You should use the name attribute to specify a radio group and use getElementsByName instead. For instance:

    <input type="radio" name="myRadio" checked><label>1</label>
<input type="radio" name="myRadio"><label>2</label>

    JS

    var radiobox = document.getElementsByName("myRadio");
alert(radiobox[0].checked);
