1、下载Vditor插件

npm i vditor

我的vditor版本是3.10.2，大家可以自行选择下载最新版本

官网：Vditor 一款浏览器端的 Markdown 编辑器，支持所见即所得（富文本）、即时渲染（类似 Typora）和分屏 - 链滴

示例：

Vditor 示例 - 链滴

2、引入vue文件

import Vditor from "vditor";
import "vditor/dist/index.css";

 3、封装vditor自定义组件

<template><div><div:id="vidtorId"class="vditor":class="{ 'vditor-hidden': showPreview }"></div></div>
</template>

<script setup>
import Vditor from "vditor";
import "vditor/dist/index.css";
import { getToken } from "@/utils/auth";
const { proxy } = getCurrentInstance();
const props = defineProps({height: {type: [Number, String],default: "inherit",},modelValue: {type: String,default: "",},knwlgId: {type: String,default: "",},showPreview: {type: Boolean,default: false,},disabled: {type: Boolean,default: false,},// 额外的formData参数extraData: {type: Object,default: () => ({}),},uploadURL: {type: String,default: "",},previewURL: {type: String,default: "/ekms/images/v1/preview/",},placeholder: {type: String,default: "",},
});const vidtorId = ref("vidtor-" + +new Date() + ((Math.random() * 1000).toFixed(0) + "")
);// 图片上传地址判断，这里大家可以根据自己需求写死或通过props传入
const imgUploadUrl = computed(() => {return !props.uploadURL? `/ekms/images/v1/upload?knwlgId=${props.knwlgId}`: props.uploadURL;
});watch(() => props.showPreview,(newValue, oldValue) => {let previewDom =contentEditor.value.vditor.toolbar.elements.preview.firstChild;let isPreview = previewDom.className.indexOf("vditor-menu--current") > -1;emits("update:showPreview", isPreview ? false : true);previewDom.click();}
);const emits = defineEmits(["update:modelValue","update:showPreview","setHtml",
]);
const contentEditor = ref(null);onMounted(() => {contentEditor.value = new Vditor(vidtorId.value, {height: props.height,mode: "wysiwyg", //所见即所得（wysiwyg）、即时渲染（ir）、分屏预览（sv）value: props.modelValue,cdn: import.meta.env.VITE_APP_VDITOR_API,placeholder: props.placeholder,toolbarConfig: {pin: true,// hide: true,},// outline: {//   enable: true, //展示大纲，position默认left// },cache: {enable: false, // 是否使用 localStorage 进行缓存},preview: {mode: "both", //显示模式delay: 10,actions: [],theme: {path: `${import.meta.env.VITE_APP_VDITOR_API}/dist/css/content-theme`,},},toolbar: ["emoji","headings","bold","italic","strike","link","|","list","ordered-list","check","outdent","indent","|","quote","line","code","inline-code","insert-before","insert-after","|",{//自定义上传hotkey: "",name: "upload",tip: "上传图片",className: "right",},"table","|","undo","redo","|","code-theme","content-theme","preview",// 自定义清空内容的菜单{hotkey: "⇧⌘S",name: "clearAll",tipPosition: "n",tip: "清空内容",className: "right",icon: '<svg t="1696926237451" class="icon" viewBox="0 0 1024 1024" version="1.1" xmlns="http://www.w3.org/2000/svg" p-id="2371" width="180" height="180"><path d="M512 838.858c10.89 0 19.732-9.158 19.732-20.43v-490.275c0-11.273-8.842-20.43-19.732-20.43s-19.755 9.157-19.755 20.43v490.275c0 11.272 8.842 20.43 19.755 20.43M629.877 838.813c10.935 0.428 20.138-8.37 20.475-19.688l28.665-489.69c0.427-11.272-8.077-20.745-18.99-21.195-10.935-0.405-20.137 8.415-20.475 19.688l-28.665 489.713c-0.405 11.317 8.1 20.767 18.99 21.172M848.038 185.142h-197.708v-81.653c0-22.545-17.685-40.882-39.51-40.882h-197.64c-21.87 0-39.532 18.338-39.532 40.882v81.653h-197.685c-10.913 0-19.755 9.158-19.755 20.475 0 11.272 8.843 20.407 19.755 20.407h39.577l39.488 653.67c6.367 44.73 35.415 81.72 79.065 81.72h355.793c43.65 0 71.573-37.44 79.088-81.72l39.488-653.67h39.578c10.867 0 19.755-9.135 19.755-20.408 0-11.317-8.888-20.475-19.755-20.475M413.157 103.49h197.64v81.653h-197.64v-81.653zM729.418 879.695c-2.655 21.555-17.73 40.86-39.533 40.86h-355.793c-21.87 0-36.54-19.057-39.532-40.86l-39.532-653.67h513.945l-39.555 653.67zM394.145 838.858c10.89-0.473 19.373-9.9 18.99-21.195l-29.070-489.712c-0.427-11.273-9.585-20.070-20.475-19.665-10.913 0.428-19.463 9.9-19.013 21.173l29.093 489.712c0.36 11.295 9.54 20.070 20.475 19.688z" p-id="2372"></path></svg>',click() {contentEditor.value.setValue("");},},],// vditor结构渲染完成后after: () => {emits("setHtml", getValue(), getHTML());// 这里根据传入的disabled来设置vditor是否可输入内容props.disabled && contentEditor.value.disabled();},input: () => {// 变更事件回调emits("setHtml", getValue(), getHTML());},// 上传图片upload: {accept: "image/*", // 图片类型fieldName: "file",url: import.meta.env.VITE_APP_BASE_API + imgUploadUrl.value, // 图片上传的接口路径extraData: props.extraData, // 要携带的额外的formData参数headers: {Authorization: "Bearer " + getToken(), // 用户身份信息},filename(name) {  // 过滤特殊字符return name.replace(/[^(a-zA-Z0-9\u4e00-\u9fa5\.)]/g, "").replace(/[\?\\/:|<>\*\[\]\(\)\$%\{\}@~]/g, "").replace("/\\s/g", "");},// 粘贴图片的情况下上传的接口路径linkToImgUrl: import.meta.env.VITE_APP_BASE_API + imgUploadUrl.value,max: 20 * 1024 * 1024,multiple: false,withCredentials: false,// 图片上传校验，可以校验图片大小及类型validate(files) {const isLt2M = files[0].size / 1024 / 1024 < 20;if (!isLt2M) {proxy.$modal.msgError("上传图片大小不能超过 20MB!");}if (!files[0].type.includes("image")) {return proxy.$modal.msgError("仅支持上传图片！");}},//粘贴图片回显处理，如果有图片加了防盗链，则让后台代理替换成自己的图片linkToImgFormat(responseText) {let res = JSON.parse(responseText);if (!res.data?.imgId) return;let end = JSON.stringify({msg: "",code: 0,data: {originalURL:import.meta.env.VITE_APP_BASE_API +props.previewURL +res.data?.imgId, //图片原始地址记录到本地文件中，可以防止跨站点调用。url:import.meta.env.VITE_APP_BASE_API +props.previewURL +res.data?.imgId, //图片链接记录到本地文件中，可以防止跨站点调用。},});return end;},format(files, responseText) {var res = JSON.parse(responseText);if (!res.data?.imgId) return;//图片回显nextTick(() => {emits("setHtml", getValue(), getHTML());});return JSON.stringify({msg: "",code: 0,data: {errFiles: [],succMap: {[res.data.imgPath]:import.meta.env.VITE_APP_BASE_API +props.previewURL +res.data?.imgId,},},});},},});
