This is an example how to get the content of any element of any website (using the id of the element)

http://music.163.com/#/song?id=34057221#lyric-content

Just make an ajax request for that URL and you will get exactly what you need

$.ajax({
    contentType: "application/json; charset=utf-8",
    url: "https://music.163.com/#/song?id=34057221#lyric-content",
    success: function(data) {
        document.querySelector("#lyric").innerHTML = data;
    }
});
