I have two radio buttons to toggle two alternative texts and it works:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN"
   "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<head>
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"
            type="text/javascript"></script>
    <style type="text/css">
        .displayNone { display: none; }
    </style>
</head>

<body>

    <input type="radio" name="toggle" />A
    <input type="radio" name="toggle" />B

    <span class="A">A</span>
    <span class="B displayNone">B</span>

<script type="text/javascript">
    $('input[name=toggle]').change(function() {
        $('.A, .B').toggleClass('displayNone');
    })
</script>

</body>
</html>

Now I want to make it three radio buttons to toggle between three texts:

<input type="radio" name="toggle" />A
<input type="radio" name="toggle" />B
<input type="radio" name="toggle" />C

<span class="A">A</span>
<span class="B displayNone">B</span>
<span class="C displayNone">C</span>

The solution I’m thinking about looks too verbose. What would be the clean one?

    One further approach:

    $('input:radio[name="toggle"]').change(
    function(){
        $('span')
            .eq($(this).index())
            .removeClass('displayNone')
            .siblings('span')
            .addClass('displayNone');
    });​

    JS Fiddle demo.

    Edited to add, for the more up-to-date browsers, a pure CSS means of accomplishing the same:

    input[type=radio]:nth-child(1):checked ~ span:nth-of-type(1),
input[type=radio]:nth-child(2):checked ~ span:nth-of-type(2),
input[type=radio]:nth-child(3):checked ~ span:nth-of-type(3){
    height: 1em;
    width: 100%;
    background-color: #f90;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -o-transition: all 1s linear;
    -moz-transition: all 1s linear;
    transition: all 1s linear;
}

span {
    display: block;
    overflow: hidden;
    height: 0;
    width: 0;
    background-color: #fff;
    -webkit-transition: all 1s linear;
    -ms-transition: all 1s linear;
    -o-transition: all 1s linear;
    -moz-transition: all 1s linear;
    transition: all 1s linear;
}​
