如何在JS中设置youtube主题参数

Question

我一直在用Javascript嵌入youtube播放列表，但我无法将主题更改为浅色。所有其他参数都有效，但这一个没有通过。

这就是它应该如何工作：

  var defoptions = {
        autoplay: false,
        user: null,
        playlist: null,
        carousel: createCarousel,
        player: createPlayer,
        thumbnail: createThumbnail,
        max_results: 25, // does not apply to playlists
        loaded: function () {},
        playopts: {
            autoplay: 0,
            egm: 1,
            autohide: 1,
            fs: 1,
            showinfo: 0,
            rel: 0,
            theme: light
        }
    };

有什么想法吗？

谢谢！

这是整件事，它还远未完成，但首先我需要找出如何改变主题。

<style>
#container{
    background-color: #F1F1F1;
    padding: 20px;
}
.yt-descript{
    max-width: 100px;
    font-family: verdana;
    font-weight: bold;
    font-size: 9pt;
    margin: 2px;
}

.player {
    width: 100%;
    height: 305px;
    overflow: hidden;
    background-color: #F1F1F1 ;
    position: relative;
}

.youtube .carousel {
    width: 20%;
    height: 100%;
    overflow-y: auto;
    overflow-x: hidden;
    position: absolute;
    right: 0px;
    z-index: 3;
}
.youtube .thumbnail {
    margin-left: 2px;
    width: 90%;
    border: 1px solid black;
}
.youtube iframe.player {
    width: 80%;
    height: 100%;
    overflow: auto;
    border: 0;
}
</style>

主题需要对字符串值进行赋值，所以请尝试以下操作：

var defoptions = {
    autoplay: false,
    user: null,
    playlist: null,
    carousel: createCarousel,
    player: createPlayer,
    thumbnail: createThumbnail,
    max_results: 25, // does not apply to playlists
    loaded: function () {},
    playopts: {
        autoplay: 0,
        egm: 1,
        autohide: 1,
        fs: 1,
        showinfo: 0,
        rel: 0,
        theme: "light",
        color: "white"
    }
};
