For the following HTML:

<form name="myForm">
 <label>One<input  name="area"  type="radio" value="S"  /></label>
 <label>Two<input name="area"   type="radio" value="R" /></label>
 <label>Three<input name="area"   type="radio" value="O" /></label>
 <label>Four<input name="area" type="radio" value="U" /></label>
</form>

Changing from the following javascript code:

$(function() {
 var myForm = document.myForm ;
 var radios = myForm.area ;
// Loop through radio buttons
 for (var i=0; i<radios.length; i++) {
if (radios[i].value == "S") {
radios[i].checked = true ;  // Selected when form displays
radioClicks() ;                         // Execute the function, initial setup
}
 radios[i].onclick = radioClicks ;  // Assign to run when clicked
 }  
 });

Thanks

EDIT: The response I selected answers the question I asked, however I like the answer that uses bind() because it also shows how to distinguish the group of radio buttons

$(function() {
    $('input[@type="radio"]').click(radioClicks);

$(function() {

  $("form#myForm input[type='radio']").click( fn );

});

function fn()
{
   //do stuff here
}

I think something like this should work (but it's untested):

$("input[@type='radio']").each(function(i) {
    if (this.val() == 'E') {
        radioClicks();
        this.get().checked = true;
    }
}
$("input[@type='radio']").click(radioClicks);

$(function() {
    $('#myForm :radio').each(function() {
        if ($(this).value == 'S') {
            $(this).attr("checked", true);
            radioClicks();
        }

        $(this).click(radioClicks);
    });
});

  $( document ).ready( function() { 

      $( "input[name='area']" ).bind( "click", radioClicks )

  });

  function radioClicks()
  {
      alert( $( this ).val() );
  }

I like to use bind() instead of directly wiring the event handler because you can pass additional data to the event hander (not shown here but the data is a third bind() argument) and because you can easily unbind it (and you can bind and unbind by group--see the JQuery docs).
