div 轮播？

问题描述

我有一个父 div，除以 2 个其他 div，在其中一个 div 中，我想制作一个 div 轮播，但我既不能将这些 div 放在一起，也不能使其与 JS 一起使用。

我尝试使用 display inline-block 和 flex 使它们彼此相邻，尽管 JS 代码有效，但这不是我的想法。

const leftArrow = document.querySelector('.left-arrow');
const rightArrow = document.querySelector('.right-arrow');
let slide = document.querySelectorAll('.slide');

leftArrow.addEventListener('click',()=>{
  slide.forEach(slide => {
    slide.style.transform = 'translateX(0px)'; // 200px is just so I can see if the movement works
  })
});

rightArrow.addEventListener('click',()=>{
  slide.forEach(slide => {
    slide.style.transform = 'translateX(200px)'; // 200px is just so I can see if the movement works
  })
});

解决方法

您需要一个仅围绕幻灯片的包装器 div。它将具有 overflow: hidden 和一个比父元素宽的 width。滑动时对包装器应用负值 margin-left 是很常见的，但对幻灯片应用 translate 也可以。

如果您处理预先确定的尺寸，事情会更容易，否则您想使用 JS 从幻灯片中获取测量值并进行一些数学运算。包装纸的宽度应该是幻灯片宽度的总和。如果您的包装器足够宽，display: inline-block 会将所有内容放在同一行上。
