I need to add a check for Radio Button in my java script code for the form I am developing using Oracle portal 10g to make sure that one of the Radio Button is checked.I have code as per attached file for text field and fields which are selectable from the drop down menu.
 
What do I need to add or modify in my java script so that I can ensure Radio Button is checked.
Please let me know if more information is needed.
Thank you very much .

Try this

Put it in an external file so you do not need to do all that messy HTP.p and HTP.print (why is there a difference?

<script type="text/javascript">
function IsSelected(s) {
  return s.options[s.selectedIndex].value != "";
}
function IsEmpty(s){  
  if (s.length != undefined) {
    for (i=0; i<s.length;i++){
      if (s[i].value !="") return true;
    }
    return false;
  }
  else return s.value != "";
}

function IsChecked(but) {
  if (!but.length) return but.checked;
  for (var i=0;i<but.length;i++) {
    if (but[i].checked) return true;
  }
  return false;
}

function validateForm(theForm) {
  if (IsEmpty(theForm.IN_LAST_NAME)) {
    alert("Please enter last name."); 
    theForm.IN_LAST_NAME.focus();
    return false;
  } 
  
  if (!IsSelected(theForm.IN_REQUESTED_CREDIT_HOURS)) {
    alert("Please select credit hours!"); 
    theForm.IN_REQUESTED_CREDIT_HOURS.focus();
    return false;
  } 

  if (!IsChecked(theForm.SOME_RADIO_OR_CHECKBUTTON_SET)) {
    alert("Please check a radio or check button!"); 
    return false;
  } 
  return true;
}
</script>

Open in new window


I have changed the code so you can do

<form onsubmit="return validateForm(this)"

instead of having the name of the form floating around the place

I also deleted an unused focus function and cleaned up the rest

Thank you mplungjan for the input.I already have coded for other fields so I did not change to external file.Besides I do not know how to use  external file for validation.I am creating this form through a oracle package I am writing.
I  tried as per attached file but now it shows the Alert message and even after clicking OK and selecting one of the Radio button it keeps giving me same Alert and does not go beyond that point.What could be wrong in the code?


Thank you very much.
