React Hooks 封装可粘贴图片的输入框组件（wangeditor）

需求是需要一个文本框但是可以支持右键或者ctrl+v粘贴图片，原生js很麻烦，那不如用插件来实现吧~我这里用的wangeditor插件，初次写初次用，可能不太好，但目前是可以达到实现需求的一个效果啦！后面再改进吧~

封装了个文本框组件，上代码吧直接：

复制代码

import React, {
  useRef,
  useEffect,
  forwardRef,
  useImperativeHandle
} from "react";
import WangEditor from "wangeditor";
import { handleFetchPostJson } from "../../service/request";
import "./editimg.scss";

// 过滤所有标签及属性
let reHtml =
  /(&lt;|<(?!img|p|\/p|h1|h2|h3|h4|h5|h6|\/h1|\/h2|\/h3|\/h4|\/h5|\/h6|span|\/span|br).*?>|&gt;)/gi;

const EditorImgComponent = forwardRef(
  ({ isPlot, onContentChange, editorConfig, isDialog }, ref) => {
    let wangEditor = useRef();
    const editorRef = useRef(null);

    useEffect(() => {
      if (editorRef.current) {
        wangEditor.current = new WangEditor(editorRef.current);
        const editor = wangEditor.current;
        editor.config.menus = editorConfig;
        // 允许粘贴图片
        editor.config.showLinkImg = false;
        editor.config.pasteFilterStyle = true;

        // 监控变化，同步更新到 textarea
        editor.config.onchange = (html) => {
          onContentChange(html);
        };

        editor.config.placeholder =
          "<div>为了更加快速的定位查找问题，请您按照如下方式反馈相关信息：<br/>  # 云分析请提供项目编号、章节名称、问题描述；<br/># 云分析请提供分析参数和提示信息截图；<br/> # 云图汇工具 请描述问题，附上相关作图数据；<br/>支持粘贴图片，为了更好的展示效果，请将文案和图片换行展示</div>";
        // 粘贴时去掉标签
        editor.config.pasteTextHandle = (content) => {
          content = content.replace(/[\r\n]/g, "");
          content = content.replace(/\'/g, '"');
          content = content.replace(reHtml, "");
          return content;
        };
        editor.config.zIndex = 1;
        editor.config.customUploadImg = function (files, insert) {
          if (files[0].size / 1024 / 1024 > 2) {
            message.error("上传图片最大不超过2M！");
            return;
          }
          let formData = new FormData();
          formData.append("image", files[0]);
          handleFetchPostJson("v1/message/mess_pic/", formData, {
            "Content-Type": "multipart/form-data"
          }).then((res) => {
            if (res.code === 2000) {
              let time = new Date().getTime();
              insert(res.info + "?time=" + time);
            } else {
              message.error("上传失败，请重新上传！");
            }
          });
        };

        editor.create();
        return () => {
          editor.destroy();
        };
      }
    }, []);

    useImperativeHandle(
      ref,
      () => {
        return {
          editor: wangEditor.current
        };
      },
      [wangEditor.current]
    );

    return (
      <div
        ref={editorRef}
        className={
          isPlot
            ? "work-center-plot-content-editor"
            : isDialog
            ? "work-center-dialog-editor"
            : "work-center-content-editor"
        }
      />
    );
  }
);

export default EditorImgComponent;
