1. 安装依赖库

npm install @kangc/v-md-editor
npm install highlight.js@^10.7.3 markdown-it-anchor@^8.6.4

2. 全局配置（在 main.js 中）

// Markdown 编辑器配置
import VMdEditor from '@kangc/v-md-editor'
import githubTheme from '@kangc/v-md-editor/lib/theme/github'
import '@kangc/v-md-editor/lib/theme/style/github.css'
import hljs from 'highlight.js/lib/core' 
import markdownItAnchor from 'markdown-it-anchor'

// 配置 Markdown 解析器
VMdEditor.use(githubTheme, {
  Hljs: hljs,
  extend(md) {
    md.use(markdownItAnchor, {
      slugify: (s) => s.toLowerCase().replace(/[^\w\u4e00-\u9fa5]+/g, '-')
    });
  },
});

// 注册到 Vue
Vue.use(VMdEditor);

3. 创建Markdown渲染组件

在 components 目录下新建 MarkdownViewer.vue：

<template>
  <div class="markdown-wrapper">
    <!-- 左侧目录 -->
    <div class="toc" v-if="toc.length">
      <div class="toc-title">目录导航</div>
      <div
        v-for="(item, index) in toc"
        :key="index"
        :class="['toc-item', `toc-level-${item.level}`]"
      >
        <a @click="scrollToAnchor(item.anchor)">{{ item.title }}</a>
      </div>
    </div>

    <!-- 右侧内容 -->
    <div class="content">
      <v-md-editor
        :value="content"
        mode="preview"
        left-toolbar="undefined"
        @toc-change="handleTocChange"
      />
    </div>
  </div>
</template>

<script>
export default {
  props: {
    content: {
      type: String,
      required: true
    }
  },
  data() {
    return {
      toc: []
    };
  },
  methods: {
    handleTocChange(toc) {
      this.toc = toc;
    },
    scrollToAnchor(anchor) {
      const target = document.querySelector(`#${anchor}`);
      if (target) {
        target.scrollIntoView({ behavior: 'smooth' });
      }
    }
  }
};
</script>

<style scoped>
.markdown-wrapper {
  display: flex;
  min-height: calc(100vh - 120px);
}

.toc {
  width: 240px;
  padding: 15px;
  border-right: 1px solid #eaecef;
  position: sticky;
  top: 60px;
  max-height: 90vh;
  overflow-y: auto;
}

.toc-title {
  font-weight: 600;
  margin-bottom: 10px;
  color: #2c3e50;
}

.toc-item {
  line-height: 1.5;
  padding: 4px 0;
}

.toc-level-2 { margin-left: 0 }
.toc-level-3 { margin-left: 15px }
.toc-level-4 { margin-left: 30px }
.toc-level-5 { margin-left: 45px }

.content {
  flex: 1;
  padding: 20px 40px;
  max-width: 900px;
}

/* 覆盖默认样式 */
.v-md-editor >>> pre {
  background-color: #f6f8fa !important;
  padding: 16px !important;
  border-radius: 6px;
}

.v-md-editor >>> table {
  border-collapse: collapse;
  margin: 1em 0;
}

.v-md-editor >>> table td,
.v-md-editor >>> table th {
  border: 1px solid #dfe2e5;
  padding: 0.6em 1em;
}
</style>

4.假设文件存放在 public/docs 目录

5. 在页面中使用组件，并添加回到顶部按钮

<template>
  <div>
    <markdown-viewer :content="mdContent" />
    <button v-show="showBackToTop" class="back-to-top" @click="scrollToTop">回到顶部</button>
  </div>
</template>

<script>
import MarkdownViewer from '@/components/MarkdownViewer';

export default {
  components: { MarkdownViewer },
  data() {
    return {
      mdContent: '',
      showBackToTop: false,// 控制回到顶部按钮的显示与隐藏
    };
  },
  mounted() {
    // 假设文件存放在 public/docs 目录
    fetch('/docs/work.md')
      .then(res => res.text())
      .then(text => {
        this.mdContent = text;
      });

    // 监听页面滚动事件
    window.addEventListener("scroll", this.handleScroll);
  },
  beforeDestroy() {
    // 组件销毁前移除滚动监听事件，避免内存泄漏
    window.removeEventListener("scroll", this.handleScroll);
  },
  methods: {
    handleScroll() {
      // 当页面滚动距离超过 300px 时，显示回到顶部按钮
      this.showBackToTop = window.scrollY > 300;
    },
    scrollToTop() {
      // 平滑滚动到页面顶部
      window.scrollTo({
        top: 0,
        behavior: "smooth",
      });
    },
  },
};
</script>
<style scoped>
.back-to-top {
  position: fixed;
  bottom: 20px;
  right: 20px;
  padding: 10px 15px;
  background-color: #007bff;
  color: white;
  border: none;
  border-radius: 5px;
  cursor: pointer;
  z-index: 100;
}

.back-to-top:hover {
  background-color: #0056b3;
}
</style>

五、图片路径处理技巧

1. ‌本地图片‌（推荐存放在 public/md-images）：

   ![图片说明](/md-images/demo.png)
   

2. ‌网络图片‌直接使用 URL：

   ![网络图片](https://example.com/image.jpg)
