Validation of radio button group using jQuery validation plugin

With newer releases of jquery (1.3+ I think), all you have to do is set one of the members of the radio set to be required and jquery will take care of the rest:

<input type="radio" name="myoptions" value="blue" class="required"> Blue<br /><input type="radio" name="myoptions" value="red"> Red<br /><input type="radio" name="myoptions" value="green"> Green

The above would require at least 1 of the 3 radio options w/ the name of "my options" to be selected before proceeding.

The label suggestion by Mahes, btw, works wonderfully!

use the following rule for validating radio button group selection

myRadioGroupName : {required :true}

myRadioGroupName is the value you have given to name attribute

You can also use this:

<fieldset><input type="radio" name="myoptions[]" value="blue"> Blue<br /><input type="radio" name="myoptions[]" value="red"> Red<br /><input type="radio" name="myoptions[]" value="green"> Green<br /><label for="myoptions[]" class="error" style="display:none;">Please choose one.</label></fieldset>

and simply add this rule

rules: { 'myoptions[]':{ required:true }}

Mention how to add rules.
