一、在项目中下载安装富文本编辑器

npm install vue-quill-editor --save

二、在项目中引入(我这里是在main.js中全局引用了)

// 引入富文本组件
import QuillEditor from 'vue-quill-editor'
// 引入富文本组件样式
import 'quill/dist/quill.core.css'
import 'quill/dist/quill.snow.css'
import 'quill/dist/quill.bubble.css'
Vue.use(QuillEditor)
// 引入富文本组件

三、在页面中直接使用

<template>
  <el-dialog :visible.sync="visible" :title="!dataForm.id ? $t('add') : $t('update')"
             :close-on-click-modal="false" :close-on-press-escape="false" width="90%">
    <el-form :model="dataForm" :rules="dataRule" ref="dataForm"
             :label-width="$i18n.locale === 'en-US' ? '120px' : '80px'" :disabled="dataForm.flag === 1">
      <el-row style="font-weight:bold">
        <el-col><span>资讯信息</span></el-col>
        <el-divider></el-divider>
      </el-row>
      <el-row>
        <el-col :span="14">
          <el-form-item label="资讯标题" prop="xwbt">
            <el-input v-model="dataForm.xwbt" placeholder="请输入资讯标题"></el-input>
          </el-form-item>
        </el-col>
        <el-col :span="10">
          <el-form-item label="副标题" prop="fbt">
            <el-input v-model="dataForm.fbt" placeholder="请输入副标题"></el-input>
          </el-form-item>
        </el-col>
      </el-row>
      <el-row>
        <el-col :span="24">
          <el-form-item label="内容" prop="nr" class="form-item-content">
            <quill-editor ref="myQuillEditor" v-model="dataForm.nr" class="editor" :options="editorOption" />
          </el-form-item>
        </el-col>
      </el-row>

    </el-form>
    <!-- 富文本编辑器中的上传图片控件 -->
    <el-upload

    />
    <!-- 富文本编辑器中的上传图片控件 -->

    <template slot="footer">
