Question

所以这是我的小HTML页面，其中包含视频播放列表：

http://jsfiddle.net/VvR4H/3/

enter image description here

正如你所看到的，在灰色区域我有一个播放列表的内嵌列表，我现在有三个：

袋鼠战斗
澳大利亚体育
真正的足球

在每个播放列表下列出视频。

我想要实现的是我的播放列表之间的水平滚动。现在，当您单击灰色播放列表栏的左侧或右侧角落（文本被切成两半）时，它将滑动到另一个播放列表。

然而滑动不是很好。当你点击左下角时，我想让袋鼠战斗在播放列表栏的中间滑动，你能帮帮我吗？

这是我的HTML：

<div class="container">
    <ul class="playlists">
        <li class="playlist">
            <div class="title"> <span class="move-left">Real Foorball</span>
 <span>Kangaroo Fighting</span>
 <span class="move-right">Australian Sports</span>

            </div>
            <ul class="videos">
                <li class="video">Video 1 C</li>
                <li class="video">Video 2 C</li>
                <li class="video">Video 3 C</li>
            </ul>
        </li>
        <li class="playlist">
            <div class="title"> <span class="move-left">Kangaroo Fighting</span>
 <span>Australian Sports</span>
 <span class="move-right">Real Football</span>

            </div>
            <ul class="videos">
                <li class="video">Video 1 A</li>
                <li class="video">Video 2 A</li>
                <li class="video">Video 3 A</li>
            </ul>
        </li>
        <li class="playlist">
            <div class="title"> <span class="move-left">Australian Sports</span>
 <span>Real Football</span>
 <span class="move-right">Kangaroo Fighting</span>

            </div>
            <ul class="videos">
                <li class="video">Video 1 B</li>
                <li class="video">Video 2 B</li>
                <li class="video">Video 3 B</li>
            </ul>
        </li>
    </ul>
</div>

我的CSS：

ul li {
    list-style: none;
}
.container {
    position: relative;
    background: #000;
    width: 300px;
    height: 500px;
    overflow: hidden;
    font-family: sans-serif;
}
ul.playlists {
    width: 1200px;
    padding-left: 0;
    margin-top: 0;
    position: absolute;
    left: -300px;
}
ul.playlists li {
    float: left;
    width: 300px;
    height: 50px;
}
ul.playlists li.playlist .title {
    width: 100%;
    background: grey;
    color: white;
    line-height: 50px;
    text-align: center;
}
ul.playlists li.playlist .title .move-left, ul.playlists li.playlist .title .move-right {
    width: 30px;
    line-height: 50px;
    cursor: pointer;
    white-space: nowrap;
    overflow: hidden;
}
ul.playlists li.playlist .title .move-left {
    float: left;
    direction: rtl;
}
ul.playlists li.playlist .title .move-right {
    float: right;
}
ul.videos {
    clear: both;
    padding-left: 0;
}
ul.videos li {
    float: left;
    width: 250px;
    height: 50px;
    padding: 25px;
    color: white;
    background: blue;
    border-top: 1px solid black;
}

我的JavaScript：

$(".move-left").click(function () {
    $(this).parent().parent().parent().animate({
        "left": "0"
    }, 500, "linear", function () {
        console.log("yay");
    });
});

$(".move-right").click(function () {
    $(this).parent().parent().parent().animate({
        "left": "-600"
    }, 500, "linear", function () {
        console.log("yay");
    });
});

它不完整（我没有做无限循环），但我猜它有更好的动画，如你所要求的。

我将你的html分成两部分。第一个是移动慢，然后是第二个。因此，您可以查看下一个标题的一半文本，但您不必复制文本。
