如何使滚动按钮与特定的视频url关联？

<div id="video-container">
  <video id="video" controls>
    <source src="video-url.mp4" type="video/mp4">
  </video>
</div>

<button id="scroll-button">滚动按钮</button>

var scrollButton = document.getElementById("scroll-button");
scrollButton.addEventListener("click", function() {
  // 在这里执行与滚动按钮关联的操作
});

var video = document.getElementById("video");
video.src = "特定的视频URL";

<div id="video-container">
  <video id="video" controls>
    <source src="video-url.mp4" type="video/mp4">
  </video>
</div>

<button id="scroll-button">滚动按钮</button>

<script>
  var scrollButton = document.getElementById("scroll-button");
  scrollButton.addEventListener("click", function() {
    var video = document.getElementById("video");
    video.src = "特定的视频URL";
  });
</script>
