jQuery toggle class

Question

I'm having trouble adding in jQuery's toggleClass function into the rest of my code. The page has several HTML5 audio tags on it which are controlled via jQuery. I attempted to add the toggle function to my jQuery audio control function, but it's not adding the class and subsequently the audio control doesn't work.. so I suppose it's some weird syntax error.

What do you guys recommend? Below is a jsFiddle and a my (unfortunately) weak attempt :)

HTML:

<div id="music_right">
    <div class="thumbnail" id="paparazzi">
        <a class="playback">
            <img class="play" src="http://www.lucisz.com/imgs/play.png" />
        </a>
        <audio>
         <source src="../audio/fernando_garibay_paparazzisnlmix.ogg" type="audio/ogg" />
            <source src="../audio/fernando_garibay_paparazzisnlmix.mp3" type="audio/mpeg" />
            Your browser does not support HTML5 audio.
        </audio>
    </div>
    <div class="thumbnail" id="danceinthedark">
        <a class="playback">
            <img class="play" src="http://www.lucisz.com/imgs/play.png" />
        </a>
        <audio>
         <source src="../audio/fernando_garibay_danceinthedark.ogg" type="audio/ogg" />
            <source src="../audio/fernando_garibay_danceinthedark.mp3" type="audio/mpeg" />
            Your browser does not support HTML5 audio.
        </audio>
    </div>
    <div class="thumbnail" id="bornthisway">
        <a class="playback">
            <img class="play" src="http://www.lucisz.com/imgs/play.png" />
        </a>
        <audio>
         <source src="../audio/fernando_garibay_bornthisway.ogg" type="audio/ogg" />

        </audio>
    </div>
</div>

JavaScript:

var curPlaying;
$(function() {
    $(".playback").click(function(e){
        e.preventDefault();
        var song = $(this).next('audio')[0];
        song.toggleClass("playing");
        if(song.paused){
            song.play();
            if(curPlaying) $("audio", "#"+curPlaying)[0].pause();
        } else {
            song.pause();
            }
        curPlaying = $(this).parent()[0].id;
    });
});

//the function below works, but doesn't have the add/remove class functions

var curPlaying;
$(function() {
    $(".playback").click(function(e) {
        e.preventDefault();
        var song = $(this).next('audio')[0];
        if (song.paused) {
            song.play();
            if (curPlaying) $("audio", "#" + curPlaying)[0].pause();
        } else {
            song.pause();
        }
        curPlaying = $(this).parent()[0].id;
    });
});

Answer 1

$('thumbnail').toggleClass('pausing playing');

ToggleClass: Add or remove one or more classes from each element in the set of matched elements, depending on either the class's presence or the value of the switch argument.
