第一步，下载插件

npm install markdown-it

第二步，使用插件渲染

javascript 复制代码

<template>
  <div v-html="htmlContent"></div>
</template>

<script setup>
import { ref, computed } from 'vue';
import MarkdownIt from 'markdown-it';
// 创建 MarkdownIt 实例
const md = new MarkdownIt();
// 定义一个响应式的 Markdown 文本
const markdownText = ref('# Hello, World!\nThis is a markdown paragraph in script setup.');
// 通过计算属性将 Markdown 文本转换为 HTML 内容
const htmlContent = computed(() => md.render(markdownText.value));
</script>

实际页面的应用：

javascript 复制代码

<script setup>
import { inject, onMounted, ref, computed, watch } from 'vue';
import MarkdownIt from 'markdown-it';
const axios = inject('$axios');
const view = ref([]);
const getPostArticleView = async () => {
    const res = await axios({
        method: 'post',
        url: '/articles/view/1',
    });
    view.value = res.data.data;
    console.log(view);
};

let hasExecuted = false;

onMounted(() => {
    if (!hasExecuted) {
        getPostArticleView();
        hasExecuted = true;
    }
});

const md = new MarkdownIt();
// 用于存储转换后的HTML内容，初始为空
const htmlContent = ref('');
watch(view, (newView) => {
    if (newView && newView.body && newView.body.content) {
        // 当view有有效数据时，进行Markdown转换
        htmlContent.value = md.render(newView.body.content);
    }
}, { immediate: false });
</script>

<template>
    <div id="article">
        <div class="textSpring">
            <h1>{{view.title}}</h1>
            <hr>
            <div v-html="htmlContent"></div>
        </div>
    </div>
</template>

<style scoped>
    #article{
        padding: 20px;
    }

    .textSpring{
        margin: 0 auto;
        border: 1px solid black;
        border-radius: 5px;
        width: 60%;
    }
</style>
