antd+react Hook弹窗改进版

之前写过一个react Hook+antd弹窗，虽然功能实现了，但是再使用的时候仍然会有报错，虽然这个报错不影响使用的，但是，作为一个合格的前端切图仔，要再使用中发现问题，改正问题。

问题

1. 多次调用hook会创建多个相同id的盒子加入页面，并且未初始化就已经有盛放弹窗的盒子
2. 使用不够简便，一些文件的格式判断以及大小判断没有做
3. 在热更新时如果弹窗处于打开状态，会报错节点容器已经被创建

问题出现原因及修改办法

针对第一个问题和第三个我呢提主要是因为在调用hook时，就创建了弹窗盛放的容器，这个是不对的，因为虽然调用hook但是并不代表就一定要弹窗，虽然这样说有点牵强，不使用为啥调用弹窗hook。但是主要目的在于我们不应该在调用hook的时候创建容器，而是在调用初始化的时候调用，具体的修改代码，可以直接看完整版的代码
针对于第二个问题，我的解决办法是给定默认大小以及文件格式，如果传递参数就使用传递参数的来判断

    );
  };

  return {
    MyForm,
  };
};

针对于上边的form表单类型，我还自定义了两种自己封装的类型，一个是富文本类型，一种是文件类型
富文本类型

import React, { useState, useEffect } from "react";
import "@wangeditor/editor/dist/css/style.css";
import { Editor, Toolbar } from "@wangeditor/editor-for-react";

type editorType = {
  handelChange: (value: any, txt: any) => void;
};

export const MyEditor = ({ handelChange }: editorType) => {
  const [editor, setEditor] = useState(null); // 存储 editor 实例
  const [html, setHtml] = useState("");

  const toolbarConfig = {};
  const editorConfig = {
    placeholder: "请输入内容...",
    autoFocus: false,
    //插入图片
    MENU_CONF: {
      uploadImage: {
        // 单个文件的最大体积限制，默认为 2M
        maxFileSize: 4 * 1024 * 1024, // 4M
        // 最多可上传几个文件，默认为 100
        maxNumberOfFiles: 10,
        // 超时时间，默认为 10 秒
        timeout: 5 * 1000, // 5 秒
        // 用户自定义上传图片
        async customUpload(file: any, insertFn: any) {
          const formdata = new FormData();
          formdata.append("file", file);
        },
      },
    },
  };

  // 及时销毁 editor
  useEffect(() => {
    return () => {
      if (editor == null) return;
      editor.destroy();
      setEditor(null);
    };
  }, [editor]);

  return (
    <>
      

        
         {
            setHtml(editor.getHtml().replace(/(^\s*)|(\s*$)/g, ""));
            handelChange(
              editor.getHtml().replace(/(^\s*)|(\s*$)/g, ""),
              editor.getText()
            );
          }}
          mode="default"
          style={{ height: "300px" }}
          />
      
    
  );
};

文件类型

import React, { useEffect, useState } from "react";
import { PlusOutlined } from "@ant-design/icons";
import { Modal, Upload } from "antd";
import type { RcFile, UploadProps } from "antd/es/upload";
import type { UploadFile } from "antd/es/upload/interface";

// 传递改变函数，限制图片个数，是否裁剪
export function MyUpload({
  onChangeFn,
  fileList,
  limit,
}: {
  onChangeFn: (file: any) => void;
  fileList: any;
  limit: number;
}) {
  const getBase64 = (file: RcFile): Promise =>
    new Promise((resolve, reject) => {
      const reader = new FileReader();
      reader.readAsDataURL(file);
      reader.onload = () => resolve(reader.result as string);
      reader.onerror = (error) => reject(error);
    });

  const [previewOpen, setPreviewOpen] = useState(false);
  const [previewImage, setPreviewImage] = useState("");
  const [previewTitle, setPreviewTitle] = useState("");
  const [uploadFileList, setUploadFileList] = useState([]);

  const handleCancel = () => setPreviewOpen(false);

  const handlePreview = async (file: UploadFile) => {
    if (!file.url && !file.preview) {
      file.preview = await getBase64(file.originFileObj as RcFile);
    }

    setPreviewImage(file.url || (file.preview as string));
    setPreviewOpen(true);
    setPreviewTitle(
      file.name || file.url!.substring(file.url!.lastIndexOf("/") + 1),
    );
  };
  useEffect(() => {
    if (fileList) {
      setUploadFileList(fileList);
      onChangeFn(fileList);
    }
  }, [fileList, onChangeFn]);

  const handleChange: UploadProps["onChange"] = ({ fileList: newFileList }) => {
    setUploadFileList(newFileList);
    onChangeFn(newFileList);
  };
  return (
    <>
       false}
        >
        {uploadFileList.length >= limit ? null : (
          

            
            
上传
          
        )}
      
      
        
      
    
  );
}

总结
