如何更改班级onclick？

Question

此代码适用于soundcloud的小部件以允许远程文本按钮，我试图使其作为一个图像按钮的遥控器工作，根据所选的类别，具有不同的图片暂停/播放，而不是txt_on_pause txt_on_play。关于如何切换的任何想法？

$(function () {
    var widgetIframe = document.getElementById('sc-widget'),
        widget = SC.Widget(widgetIframe),
        txt_on_pause = '¡Escuchar música!',
        txt_on_play = 'Escuchando algo de música... (click para pausar)';
    widget.bind(SC.Widget.Events.READY, function () {
        $(".sc-toggle").html(txt_on_pause);
    });
    widget.bind(SC.Widget.Events.PAUSE, function () {
        $(".sc-toggle").html(txt_on_pause);
    });
    widget.bind(SC.Widget.Events.PLAY, function () {
        $(".sc-toggle").html(txt_on_play);
    });
    $(".sc-toggle").click(function (e) {
        e.preventDefault();
        widget.toggle();
    });
});

使用addClass和removeClass功能应该有效。

$(function () {
    var widgetIframe = document.getElementById('sc-widget'),
        widget = SC.Widget(widgetIframe),
        txt_on_pause = '¡Escuchar música!',
        txt_on_play = 'Escuchando algo de música... (click para pausar)';

    widget.bind(SC.Widget.Events.READY, function () {
        $(".sc-toggle")
            .removeClass('pause')
            .removeClass('play')
            .addClass('ready'));
    });
    widget.bind(SC.Widget.Events.PAUSE, function () {
        $(".sc-toggle")
            .removeClass('play')
            .removeClass('ready')
            .addClass('pause');
    });
    widget.bind(SC.Widget.Events.PLAY, function () {
        $(".sc-toggle")
            .removeClass('pause')
            .removeClass('ready')
            .addClass('play');
    });
    $(".sc-toggle").click(function (e) {
        e.preventDefault();
        widget.toggle();
    });

});
