[RESOLVED] How do you disable radio Group?

Does anyone know how to disable a Radio group if one of them is checked?

... You mean, make it so you can only pick one radio button in three?
Give them the same name attribute.
<input type="radio" name="NAME" value="1" />
<input type="radio" name="NAME" value="2" />
<input type="radio" name="NAME" value="3" />

No what I am trying to do is if one is checked onload then disable all of them in that group. This is what I have so far but it only diables the one checked.

Code:

---

<script type="text/javascript">
<!--
function disableCheckBox() {
        var obj=document.forms["form1"];
            for (i=0;i<obj.length;i++) {
                with (obj[i]) {
                    if (type=='radio' && checked) {
                        disabled=true;
                    }
                }
            }
    }
//-->
</script>

Try this function out:

Code:

---

/**
 * @class    window
 *
 * @function  disableRadioGroups
 *    Searches through all the FORMs on the page and disables groups of radio
 *    buttons if one of them is checked.
 *
 * @param  void
 * @return  void
 */
function disableRadioGroups() {
  var forms, el, radioGroup;
  var i = end = j = elsEnd = rg = rgEnd = 0;
 
  if (document.getElementsByTagName) {
    forms = document.getElementsByTagName('form');
    /* Loop through all the FORMs */
    for (i, end = forms.length; i < end; i++) {
      /* Loop through each form element */
      for (j = 0, elsEnd = forms[i].elements.length; j < elsEnd; j++) {
        el = forms[i].elements[j];
        /* If this is a checked, enabled radio button in a radio group... */
        if (!el.disabled
            && el.nodeName === 'INPUT'
            && el.type == 'radio'
            && el.checked
            && forms[i].elements[el.name].length) {
          radioGroup = forms[i].elements[el.name];
          /* Loop through radio group and disable buttons */
          for (rg = 0, rgEnd = radioGroup.length; rg < rgEnd; rg++) {
            radioGroup[rg].disabled = true;
          }
        }
      }
    }
  }
}


window.onload = function() {
  disableRadioGroups();
};
