先上效果图

如图所示，在网页中，能直接解析markdown文档，并且生成目录大纲，也支持点击目录标题跳转到对应栏目中，下面就来讲讲是如何实现此功能的。

1、下载vue-markdown

yarn add vue-markdown

2、在页面中渲染markdown文件

<template><div><VueMarkdownclass="api-content":source="markdownContent"id="content"/></div>
</template><script>
import VueMarkdown from "vue-markdown";export default {components: {VueMarkdown,},data() {return {markdownContent: "",};},mounted() {this.loadMarkdownFile();},methods: {async loadMarkdownFile() {try {// api.md文件存放在根目录下的public文件夹中const response = await fetch("/api.md");const markdownText = await response.text();this.markdownContent = markdownText;} catch (error) {console.error("Failed to load the Markdown file:", error);}}, },
};
</script>

此时，打开浏览器查看，页面中已经正常渲染markdown文件了。

3、生成目录大纲

现在，我们需要有目录大纲方便我们查看文档。我的思路是，首先拿到markdown文件的html结构，然后找到所有H1-H5的标题标签，并给这些标签设置id，生成一个新数组，通过这个数组生成目录结构，说干就干。

//html部分<div class="api-tree" id="tree"><el-tree:data="tree":default-expand-all="true"@node-click="handleNodeClick"></el-tree>
</div>// js部分
catalogTree() {const content = document.getElementById("content").children;var arr = [];let currentHightestLevel;let parentId;let index = 0;for (let i = 0; i < content.length; i++) {let header = content[i].localName;if (/\b[h][0-9]\b/.test(header)) {let ele = $(content[i]);let name = ele.text();// 设置idele.attr("id", i);let id = i;if (index === 0 || header <= currentHightestLevel) {currentHightestLevel = header;parentId = id;}arr.push({id: id,label: name,parentId: parentId == id ? "0" : parentId,});index++;}}const tree = [];arr.forEach((item) => {if (item.parentId === "0") {tree.push(this.convertArrayToTree(arr, item));}});this.tree = tree;
},
convertArrayToTree(arr, node) {for (let i = 0; i < arr.length; i++) {if (arr[i].parentId === node.id) {const res = this.convertArrayToTree(arr, arr[i]);if (node.children) {node.children.push(res);} else {node.children = [res];}}}return node;
},
handleNodeClick(data) {let anchorElement = document.getElementById(data.id);if (anchorElement) {anchorElement.scrollIntoView({behavior: "smooth",block: "end",});}
},

4、大功告成，最后，附上全部代码，带css样式

<template><div class="page-api" id="myElement"><div class="api-tree" id="tree"><el-tree:data="tree":default-expand-all="true"@node-click="handleNodeClick"></el-tree></div><VueMarkdownclass="api-content":source="markdownContent"id="content"/></div>
</template><script>
import VueMarkdown from "vue-markdown";
import $ from "jquery";export default {components: {VueMarkdown,},data() {return {markdownContent: "",tree: [],};},mounted() {this.loadMarkdownFile();},methods: {async loadMarkdownFile() {try {const response = await fetch("/api.md");const markdownText = await response.text();this.markdownContent = markdownText;this.$nextTick(() => {this.catalogTree();});} catch (error) {console.error("Failed to load the Markdown file:", error);}},catalogTree() {const content = document.getElementById("content").children;var arr = [];let currentHightestLevel;let parentId;let index = 0;for (let i = 0; i < content.length; i++) {let header = content[i].localName;if (/\b[h][0-9]\b/.test(header)) {let ele = $(content[i]);let name = ele.text();// 设置idele.attr("id", i);// let id = ele.children("a").attr("id");let id = i;if (index === 0 || header <= currentHightestLevel) {currentHightestLevel = header;parentId = id;}arr.push({id: id,label: name,parentId: parentId == id ? "0" : parentId,});index++;}}const tree = [];arr.forEach((item) => {if (item.parentId === "0") {tree.push(this.convertArrayToTree(arr, item));}});this.tree = tree;},convertArrayToTree(arr, node) {for (let i = 0; i < arr.length; i++) {if (arr[i].parentId === node.id) {const res = this.convertArrayToTree(arr, arr[i]);if (node.children) {node.children.push(res);} else {node.children = [res];}}}return node;},handleNodeClick(data) {let anchorElement = document.getElementById(data.id);let scrollPosition = anchorElement.offsetTop - 20;let myElement = document.getElementById("myElement");myElement.scrollTo({left: 0,top: scrollPosition,behavior: "smooth",});// if (anchorElement) {//     anchorElement.scrollIntoView({//         behavior: "smooth",//         block: "end",//     });// }},},
};
</script><style lang="scss">
