vue3通过按钮实现横向滚动或鼠标滚动横坐标滚动

效果图：可点击左右文字进行滚动、或通过滚动鼠标 内容左右滚动

<template>
  <div class="Home">
    <div style="display: flex;height: 100%;align-items: center;">
      <div @click="scrollLeft()" style="width: 80px;text-align: center;font-size: 30px;">
        左
      </div>
      <div ref="scrollContainerRef" class="testContent" @scroll="isSrcoll($event)">
        <span v-for="item in 15" :key="item" class="test_card">
          {{item}}
        </span>
      </div>
      <div @click="scrollRight()" style="width: 80px;text-align: center;font-size: 30px;">
        右
      </div>
    </div>
  </div>
</template>
<script setup>
onMounted(() => {
  let div = document.querySelector(".testContent");
  // 监听 dom
  div.addEventListener("wheel", function (e) {
    let left = -e.wheelDelta || e.deltaY / 2;
    // console.log("wheelDelta:", -e.wheelDelta, "deltaY :", e.deltaY);
    // 修改滚动条位置
    div.scrollLeft = div.scrollLeft + left;
  });

});
//点击按钮横向滚动模块
let scrollContainerRef = ref(null)
const scrollLeft = () => {
  scrollContainerRef.value.scrollBy({
    left: -600, // 每次点击滚动的距离
    behavior: 'smooth',
  });

}
const scrollRight = () => {
  scrollContainerRef.value.scrollBy({
    left: 600, // 每次点击滚动的距离
    behavior: 'smooth',
  });

}
// 判断左右按钮是否显示（具体显示隐藏逻辑不写了）
const isSrcoll = (event) => {
  let el = event.target;
  if (Math.ceil(el.scrollLeft + el.clientWidth) >= el.scrollWidth) {
    console.log("已滚动到最右侧");
  }
  if (!el.scrollLeft) {
    console.log(el.scrollLeft, "左边左边");
  }

}
