javascript - 图像滑块中的连续运动

我有一个使用滑动分隔线的图像滑块。我试图操纵它，以便当我单击一个按钮（上一个/下一个）时，开关将是连续的，就好像分隔开关是一个。在当前幻灯片中，单击按钮时，另一个分隔线会从较远的位置替换当前分隔线。对如何进行单个动作有任何想法吗？同时保持与代码中相同的动作（从左到右/从右到左）。

HTML：

<div id="wrapper">
  <div id="nav">
    <button id="prev" disabled>&lt;&lt;&lt;</button>
    <button id="next">&gt;&gt;&gt;</button>
  </div>
  <div id="mask">
    <div id="item1" class="item">
      <a name="item1"></a>
      <div class="content">
        <img id="image1" src="http://placehold.it/350x150"/>
        <img id="image2" src="http://placehold.it/350x150"/>
