Using jQuery, what is the best way to set onClick event listeners for radio buttons?

Question

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

Answer 1

$(document).ready(function(){
    $("input[name='area']").bind("click", radioClicks);
});

functionradioClicks() {
    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).

Answer 2

$( function() {
    $("input:radio")
        .click(radioClicks)
        .filter("[value='S']")
        .attr("checked", "checked");
});
