vue 横向时间线组件

你可以尝试使用 Vue.js 开发时间线组件，具体实现可以参考以下步骤：

1. 安装必要的依赖：

npm install vue moment

2. 创建一个 TimelineItem.vue 组件，用于展示单个时间线条目的内容：

<template>
  <div class="timeline-item">
    <div class="timeline-item__date">{{ formattedDate }}</div>
    <div class="timeline-item__content">
      <slot></slot>
    </div>
  </div>
</template>

<script>
  import moment from 'moment';
  
  export default {
    props: {
      date: {
        type: String,
        required: true
      }
    },
    computed: {
      formattedDate() {
        return moment(this.date).format('YYYY-MM-DD');
      }
    }
  }
</script>

<style scoped>
  .timeline-item {
    position: relative;
    padding: 1rem;
    border-left: 2px solid #e5e5e5;
  }
  
  .timeline-item__date {
    position: absolute;
    top: 0;
    left: -7rem;
    width: 6rem;
    text-align: right;
    font-size: 0.8rem;
    color: #999;
  }
  
  .timeline-item__content {
    margin-left: 2rem;
  }
</style>

3. 创建一个 Timeline.vue 组件，用于容纳多个时间线条目，并实现横向滚动：

<template>
  <div class="timeline">
    <div class="timeline__wrapper" ref="wrapper">
      <div class="timeline__container" ref="container">
        <slot></slot>
      </div>
    </div>
    <div class="timeline__controls">
      <button @click="scrollLeft">←</button>
      <button @click="scrollRight">→</button>
    </div>
  </div>
</template>

<script>
  export default {
    methods: {
      scrollLeft() {
        this.$refs.wrapper.scrollBy({
          left: -200,
          behavior: 'smooth'
        });
      },
      scrollRight() {
        this.$refs.wrapper.scrollBy({
          left: 200,
          behavior: 'smooth'
        });
      }
    }
  }
</script>

<style scoped>
  .timeline {
    position: relative;
    padding: 1rem 0;
    overflow-x: auto;
  }
  
  .timeline__wrapper {
    display: flex;
    flex-direction: row;
    align-items: flex-start;
  }
  
  .timeline__container {
    display: flex;
    flex-direction: row;
  }
  
  .timeline__controls {
    position: absolute;
    top: 0;
    right: 0;
    display: flex;
    flex-direction: row;
    align-items: center;
    justify-content: space-between;
    width: 4rem;
    height: 100%;
    background-color: rgba(255, 255, 255, 0.8);
    z-index: 1;
  }
  
  .timeline__controls button {
    border: none;
    background-color: transparent;
    font-size: 1.2rem;
    cursor: pointer;
    outline: none;
  }
</style>

4. 在需要展示时间线的页面中使用 Timeline 和 TimelineItem 组件：

<template>
  <div>
    <h1>My Timeline</h1>
    <Timeline>
      <TimelineItem date="2021-01-01">
        <h3>Event A</h3>
        <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
      </TimelineItem>
      <TimelineItem date="2021-02-01">
        <h3>Event B</h3>
        <p>Sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.</p>
      </TimelineItem>
      <TimelineItem date="2021-03-01">
        <h3>Event C</h3>
        <p>Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat.</p>
      </TimelineItem>
      <TimelineItem date="2021-04-01">
        <h3>Event D</h3>
        <p>Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur.</p>
      </TimelineItem>
    </Timeline>
  </div>
</template>

<script>
  import Timeline from './Timeline.vue';
  import TimelineItem from './TimelineItem.vue';
  
  export default {
    components: {
      Timeline,
      TimelineItem
    }
  }
</script>

通过以上步骤，你就可以创建一个简单的横向时间线组件，用户可以通过左右滚动查看不同时间点的事件。你可以根据自己的需求对组件进行进一步的定制和优化。
