本文为大家分享了Vue+Element UI+vue-quill-editor富文本编辑器及插入图片自定义，供大家参考，具体内容如下

1.安装

npm install vue-quill-editor --save

2.在main.js中引入

import VueQuillEditor from 'vue-quill-editor'
import 'quill/dist/quill.core.css'
import 'quill/dist/quill.snow.css'
import 'quill/dist/quill.bubble.css'
 
Vue.use(VueQuillEditor);

3. template

<div>
 
  <!-- 图片上传组件辅助-->
  <el-upload
  class="avatar-uploader"
  :action="serverUrl"
  name="img"
  :headers="header"
  :show-file-list="false"
  :on-success="uploadSuccess"
  :on-error="uploadError"
  :before-upload="beforeUpload">
  </el-upload>
  <quill-editor
  v-model="content"
  ref="myQuillEditor"
  :options="editorOption"
  @change="onEditorChange($event)"
  >
  </quill-editor>
 </div>

4.js

<script>
 const toolbarOptions = [
 ['bold', 'italic', 'underline', 'strike'],  // toggled buttons
 [{'header': 1}, {'header': 2}],    // custom button values
 [{'list': 'ordered'}, {'list': 'bullet'}],
 [{'indent': '-1'}, {'indent': '+1'}],   // outdent/indent
 [{'direction': 'rtl'}],       // text direction
 [{'size': ['small', false, 'large', 'huge']}], // custom dropdown
 [{'header': [1, 2, 3, 4, 5, 6, false]}],
 [{'color': []}, {'background': []}],   // dropdown with defaults from theme
 [{'font': []}],
 [{'align': []}],
 ['link', 'image'],
 ['clean']
 
 ]
 export default {
 data() {
  return {
  quillUpdateImg: false, // 根据图片上传状态来确定是否显示loading动画，刚开始是false,不显示
  content: null,
  editorOption: {
   placeholder: '',
   theme: 'snow', // or 'bubble'
   modules: {
   toolbar: {
    container: toolbarOptions,
    handlers: {
    'image': function (value) {
     if (value) {
     // 触发input框选择图片文件
     document.querySelector('.avatar-uploader input').click()
     } else {
     this.quill.format('image', false);
     }
    }
    }
   }
   }
  },
  serverUrl: '/manager/common/imgUpload', // 这里写你要上传的图片服务器地址
  header: {
   // token: sessionStorage.token
  } // 有的图片服务器要求请求头需要有token
  }
 },
 methods: {
  onEditorChange({editor, html, text}) {//内容改变事件
  console.log("---内容改变事件---")
  this.content = html
  console.log(html)
  },
  // 富文本图片上传前
  beforeUpload() {
  // 显示loading动画
  this.quillUpdateImg = true
  },
 
  uploadSuccess(res, file) {
  // res为图片服务器返回的数据
  // 获取富文本组件实例
  console.log(res);
  let quill = this.$refs.myQuillEditor.quill
  // 如果上传成功
  if (res.code == 200 ) {
   // 获取光标所在位置
   let length = quill.getSelection().index;
   // 插入图片 res.url为服务器返回的图片地址
   quill.insertEmbed(length, 'image', res.url)
   // 调整光标到最后
   quill.setSelection(length + 1)
  } else {
   this.$message.error('图片插入失败')
  }
  // loading动画消失
  this.quillUpdateImg = false
  },
  // 富文本图片上传失败
  uploadError() {
  // loading动画消失
  this.quillUpdateImg = false
  this.$message.error('图片插入失败')
  }
 }
 }

注意：serverUrl :文件上传地址不能直接写全路径，会出现跨域问题报错。需要在conf/index.js 中进行配置

module.exports = {
 dev: {
 // Paths
 assetsSubDirectory: 'static',
 assetsPublicPath: '/',
 host: 'localhost', // can be overwritten by process.env.HOST
 port: 8088, // can be overwritten by process.env.PORT, if port is in use, a free one will be determined
 autoOpenBrowser: true,
 cssSourceMap: true,
 proxyTable: {
  '/api': {
  target: 'http://localhost:18080/', //设置调用接口域名和端口号别忘了加http
  changeOrigin: true,
  pathRewrite: {
   '^/api': '/' //这里理解成用‘/api'代替target里面的地址，组件中我们调接口时直接用/api代替
   // 比如我要调用'http://0.0:300/user/add'，直接写‘/api/user/add'即可 代理后地址栏显示/
  }
  },
  '/manager': {
  target: 'http://localhost:18081/',
  changeOrigin: true,
  pathRewrite: {
   '^/manager': '/'
  }
  }
 }
 
 },

5.style

<style>
 .ql-editor.ql-blank, .ql-editor {
 height: 350px;
 }
</style>

6.后台图片上传接口

@RequestMapping(value = "/imgUpload")
 public Map<String ,Object> imgUpload(HttpServletRequest req, MultipartHttpServletRequest multiReq)
   throws IOException {
  
  FileOutputStream fos = new FileOutputStream(
    new File("E://fileupload//upload.jpg"));
  FileInputStream fs = (FileInputStream) multiReq.getFile("img").getInputStream();
  byte[] buffer = new byte[1024];
  int len = 0;
  while ((len = fs.read(buffer)) != -1) {
   fos.write(buffer, 0, len);
  }
  fos.close();
  Map<String ,Object> map=new HashMap<>();
  map.put("code",200);
  map.put("msg","上传成功");
  map.put("url","http://localhost:8080/tomcat.png");
  return map;//这里只做返回值测试用，url 参数为图片上传后访问地址。具体根据功能进行修改}

7.效果如下
