Vue+Element UI+vue-quill-editor富文本编辑器及插入图片自定义

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
