Javascript Function To Clear Radio Buttons

Categories : JavaScript

Once a radio button has been selected there is no way for the use to reset the selection and select nothing. This javascript function clears the radio buttons for a radio group with a name of 'radName'.

Note : This does not work if the radio group is an array.

<script language="JavaScript" type="text/javascript">
<!--
function clear_radio(radName){
  
  ' This function clears the radio buttons for the
  ' radio group with a name of radName

  var radio = document.getElementsByName(radName);
  for(var i = 0; i < radio.length; i++){
    if(radio[i].checked === true){
      radio[i].checked = false;
    }
  }
}
//-->


Note : This does not work if the radio group is an array.
