当我在幻灯片中按一个div时，如何更改另一个div的内容？

Question

我有一张幻灯片，我希望背景div更改背景图像和文本。我不确定如何完成此操作。你有提示吗？我将到目前为止的内容上传到了jsfiddle。背景div在代码中最远。

我在“点击时替换div内容”中进行了大量搜索，但是似乎无法执行任何操作，需要帮​​助。

$('#slider').click(function() {
    $('.backgroundmusic').css('background','blue');
})

使用jQuery设置“点击”回调，然后使用jQuery更改所需元素的CSS背景。如果需要，请使用$(selector).text()更改文本内容。
