javascript - 如何在href中使用没有id的目标子div？

Question

我正在使用 href 属性来定位包装器 div 中的滑块，但在 Vue 中它推动了该 id href 的路由，是否有任何替代方法不使用 href 来通过 id 来定位 div 中的滑块？

Vue中的href将被点击到该id的新路径，这就是为什么我找到禁用它的替代方法或使用其他方式来定位框？

const slide = document.querySelector(".slides")

slide.addEventListener('scroll', function(e) {
  console.log(e.target.scrollLeft)
  const slide2 = document.querySelector("#slide-2")
  console.log(slide2.offsetWidth)
})

.slider {

您可以用Element.scrollIntoView() 函数替换href

我在你的演示中编辑：

密码笔

  <a onclick="srollToPosition(1)">1</a>
    <a onclick="srollToPosition(2)">2</a>
    <a onclick="srollToPosition(3)">3</a>
    <a onclick="srollToPosition(4)">4</a>

  <div class="slides">
    <div id="slide-1">
      1
    </div>
    <div id="slide-2">
      2
    </div>
    <div id="slide-3">
      3
    </div>
    <div id="slide-4">
      4
    </div>
    <div id="slide-5">
      5
    </div>
  </div>
</div>

Javascript：

const srollToPosition = (slideNumber) => {
  const slide = document
    .getElementById(`slide-${slideNumber}`)
    .scrollIntoView({ behavior: "smooth", block: "end", inline: "nearest" });
};
