Answer 1

<强> HTML

<input type="radio" name="type" class="type" value="red">Red<br>    <!--    Red     -->
            <input type="radio" class="type" name="type" value="orange">Orange<br>  <!--    Orange  -->
            <input type="radio" class="type" name="type" value="yellow">Yellow<br>    <!--    Yellow  -->

            <input type="radio" class="type" name="type" value="blue">Blue<br>

<强> Jquery的

$(document).ready(function() {

        $('.type').change(function() {

           var value = $( 'input[name=type]:checked' ).val();
           alert(value);
             $("body").css({"backgroundColor" : value });
        });
    });
