单击水平滚动元素内的锚链接时，Div 滚动到页面顶部

问题描述 投票：0回答：1

我正在尝试用纯 CSS 创建一个水平滑块 由于某种原因，单击锚链接滚动 x 轴上的元素也会滚动 y 轴上的整个页面，将滑块放置在页面顶部

这种行为可以避免吗 （正如您在这里看到的https://developer.mozilla.org/en-US/docs/Web/CSS/scroll-behavior它应该正常工作）

见下面的GIF和我写的代码

 const scrollLinks = document.querySelectorAll('.scroll-link');

    scrollLinks.forEach(link => {
      link.addEventListener('click', (event) => {
        event.preventDefault(); // Prevent the default behavior of anchor links
        const targetId = link.getAttribute('data-target');
        const targetElement = document.getElementById(targetId);
        if (targetElement) {
          targetElement.scrollIntoView({ behavior: 'smooth' });
        }

在此修改后的代码中，我向锚链接添加了 

data-target
属性，并为它们指定了 
scroll-link
类。 JavaScript 代码拦截这些链接上的单击事件，防止默认行为，并以平滑的动画滚动到目标元素。这样，单击链接就不会在 y 轴上滚动整个页面。
