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,

  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(

  (newValue, oldValue) => {
    let previewDom =

    let isPreview = previewDom.className.indexOf("vditor-menu--current") > -1;
    emits("update:showPreview", isPreview ? false : true);
    previewDom.click();
  }
);
