该页面是一个step组件内嵌一个右下角的按钮组件

关键代码

首先，el-scrollbar组件包住一个被内容撑开的横向列

<el-scrollbar ref="scrollbar" class="scrollbar" v-if="list.length !== 0">
  <div class="step">
    <div class="event-item" v-for="item in list" :key="item.id">
      <div class="item-card" @click="detail(item.id)">
        ......
      </div>
    </div>
  </div>
</el-scrollbar>

获取el-scrollbar的scrollWidth（元素实际宽度，包括超出隐藏的部分），减去el-scrollbar的scrollLeft（元素距离左边窗口的距离），再减去el-scrollbar的clientWidth（元素包括padding、内容区的宽度，不含边框），得到可以向右移动的最边界位置。点击一次按钮，给scrollLeft或scrollRight赋一次值以更改位置。

// 滚动
handelScroll(action) {
  var scrollbar = this.$refs.scrollbar.wrap;
  // 点击按钮移动一次的步长
  var width = 500;
  // 向右可以移动的距离
  let scrollRight =
    scrollbar.scrollWidth -
    scrollbar.scrollLeft -
    scrollbar.clientWidth;
  if (action == "left") {
    if (scrollbar.scrollLeft > width) { // 判断滚动到最右时
      scrollbar.scrollLeft -= width;
    } else {
      scrollbar.scrollLeft -= scrollbar.scrollLeft;
    }
  } else {
    if (scrollRight > width) { // 判断滚动到最右时
      scrollbar.scrollLeft += width;
    } else {
      scrollbar.scrollLeft += scrollRight;
    }
  }
}

is-horizontal隐藏el-scrollbar自身的滚动条

::v-deep .scrollbar {
  .is-horizontal {
    height: 0;
    left: 0;
  }
}

横向排列宽度由内容撑开需要父元素加入white-space：nowrap，子元素加入display: inline-block;

.step {
	 height: 540px;
	 white-space: nowrap;
	 padding-top: 50px;
	 .event-item {
	   width: 320px;
	   height: 100%;
	   display: inline-block;
	 }
}
