<script setup>
// 富文本编辑器文档链接: https://www.wangeditor.com/v5/getting-started.html
// 引入富文本编辑器CSS
import '@wangeditor/editor/dist/css/style.css';
import { onBeforeUnmount, ref, shallowRef } from 'vue';
// 导入富文本编辑器的组件
import { Editor, Toolbar } from '@wangeditor/editor-for-vue';

// 编辑器实例，必须用 shallowRef
const editorRef = shallowRef();

// 内容 HTML
const valueHtml = ref('<p>hello <strong>hello world</strong></p>');
const toolbarConfig = {};
const editorConfig = ref({ placeholder: '请输入内容...', MENU_CONF: {} });

// 自定义图片上传
editorConfig.value.MENU_CONF['uploadImage'] = {
  async customUpload(file, insertFn) {
    console.log('上传图片', file);
    // 将上传的file图片转换为base64
    const base64 = URL.createObjectURL(file);

    // 这里的file为上传的图片对象,insertFn传入
    insertFn(base64, 'img');
  },
};

// 自定义视频上传
editorConfig.value.MENU_CONF['uploadVideo'] = {
  async customUpload(file, insertFn) {
    console.log('上传视频', file);
  },
};

// 富文本编辑器生成后触发
const handleCreated = editor => {
  editorRef.value = editor; // 记录 editor 实例，重要！
  console.log(editorConfig.value.MENU_CONF, 'editorConfig.value');
};

// 监听富文本编辑器粘贴行为
const customPaste = (editor, event, callback) => {
  // 获取粘贴的纯文本
  const text = event.clipboardData.getData('text/plain');
  if (text) {
    editor.insertText(text);
    event.preventDefault();
    callback(false);
  }
};

// 获取富文本html内容
const getEditorHTML = () => {
  console.log(editorRef.value.getHtml());
};

// 组件销毁时，也及时销毁编辑器
onBeforeUnmount(() => {
  const editor = editorRef.value;
  if (editor == null) return;
  editor.destroy();
});
