react hook使用UEditor引入秀米图文排版

里面坑比较多，细节也比较多

以下使用的是react 18 + ice3.0，使用其他react脚手架的配置基本相同，例如umi4

1.下载UEditor

进入UEditor仓库，找到版本v1.4.3.3，点击进去

接着下载ueditor1_4_3_3-utf8-jsp.zip版本

下载好以后开始安装依赖：npm install ，依赖安装完成后就可以打包了，最终我们项目要的就是这个打包后的文件。

打包需要使用grunt:

• 全局安装npm install -g grunt-cli
• 在项目ueditor中安装grunt依赖,npm install grunt --save-dev
• 在项目ueditor输入指令grunt default来生成一个dist文件
  

2.react项目配置UEditor

复制dist\utf8-php下的所有文件到react项目中的public\editor\ueditor下面（没有这个目录就新建一个）。
如下，注意标黄的文件是后面步骤加上的，没有这个文件是正常的：
接着引入UEditor

找到src\document.tsx文件，就这个文件就相当于其他项目中的index.html，具体使用参考document定制html,在这里引入UEditor，我们的文件存放的地址在public下面，这里写路径的时候不用写public，直接从editor开始写，/editor/ueditor/ueditor.config.js和/editor/ueditor/ueditor.all.js

注意！！如果你编辑器报错，放开下面两个注释的文件

3.react组件引入UEditor

新建src\components\ReactUeditor文件夹，分别以下几个文件

index.tsx

import React, {
    useEffect, useImperativeHandle, forwardRef } from "react";
let editor: any = null;
function UEditor(props, ref) {
   
  useEffect(() => {
   
    if (window.UE.getEditor) {
   
      setConfig(props.initData, props.config, props.setContent);
    }
    return () => {
   
      editor.destroy(props.id);
      // 组件销毁时候移除页面中id的textarea
      let tagElement = window.document.querySelector(`#ueditor-container`);
      tagElement?.parentElement?.removeChild(tagElement);
      // editor.removeListener(); //不要打开，否则返回有问题报错
    };
  }, []);

  // 初始化编辑器
  const setConfig = (initData, config, setContent) => {
   
    editor =
      window.UE &&
      window.UE.getEditor("ueditor-container", {
   
        // toolbars,
        // enableAutoSave: false,
        maximumWords: 1000000,
        scaleEnabled: false,
        autoFloatEnabled: false,
        autoHeightEnabled: false,
        initialFrameHeight: (config && config.initialFrameHeight) || 450,
		initialFrameWidth: (config && config.initialFrameWidth) || "100%",
        zIndex: 1,
      });
    editor.ready(() => {
   
      if (initData) {
   
        editor.setContent(initData); // 设置默认值/表单回显
      }
    });
    editor.addListener("blur", function () {
   
      setContent(editor.getContent());
    });
  };
  // 暴露方法
  useImperativeHandle(ref, () => ({
   
    getUEContent: () => {
   
      return editor.getContent(); // 获取编辑器内容
    },
  }));
  return <script id="ueditor-container" type="text/plain" />;
}
export default forwardRef(UEditor);

页面组件引入

import ReactUeditor from "@/components/ReactUeditor";

<Form.Item name="contents">
    <ReactUeditor onChange={
   onChange}
              autoFloatEnabled={
   type !== "detail" ? true : false}
              initData={
   initData}
              setContent={
   (val) => console.log(val)}></ReactUeditor>
</Form.Item>

这个时候就能看到效果了

4.接入秀米

参考地址

引入秀米图标和样式

xiumi-ue-dialog-v5.js

/**
 * Created by shunchen_yang on 16/10/25.
 */

UE.registerUI("dialog", function (editor, uiName) {
   
  var btn = new UE.ui.Button({
   
    name: "/* xiumi-connect */",
    title: "秀米",
    onclick: function () {
   
      var dialog = new UE.ui.Dialog({
   
        iframeUrl: "/editor/ueditor/xiumi-ue-dialog-v5.html",
        editor: editor,
        name: "xiumi-connect",
        title: "秀米图文消息助手",
        cssRules:
          "width: " +
          (window.innerWidth - 80) +
          "px;" +
          "height: " +
          (window.innerHeight - 280) +
          "px;z-index:100000",
      });
      dialog.render();
      dialog.open();
    },
  });
  return btn;
});

xiumi-ue-v5.css

.edui-button.edui-for-xiumi-connect .edui-button-wrap .edui-button-body .edui-icon {
   
    background-image: url("./xiumi-connect-icon.png") !important;
    background-size: contain;
}

通过iframe 嵌入秀米

internal.js

(function () {
   
  var parent = window.parent;
  //dialog对象
  dialog = parent.$EDITORUI[window.frameElement.id.replace(/_iframe$/, "")];
  //当前打开dialog的编辑器实例
  editor = dialog.editor;

  UE = parent.UE;

  domUtils = UE.dom.domUtils;

  utils = UE.utils;

  browser = UE.browser;

  ajax = UE.ajax;

  $G = function (id) {
   
    return document.getElementById(id);
  };
  //focus元素
  $focus = function (node) {
   
    setTimeout(function () {
   
      if (browser.ie) {
   
        var r = node.createTextRange();
        r.collapse(false);
        r.select();
      } else {
   
        node.focus();
      }
    }, 0);
  };
  utils.loadFile(document, {
   
    href:
      editor.options.themePath +
      editor.options.theme +
      "/dialogbase.css?cache=" +
      Math.random(),
    tag: "link",
    type: "text/css",
    rel: "stylesheet",
  });
  lang = editor.getLang(dialog.className.split("-")[2]);
if (lang) {
   
    domUtils.on(window, "load", function () {
   
      var langImgPath =
        editor.options.langPath + editor.options.lang + "/images/";
      //针对静态资源
      for (var i in lang["static"]) {
   
        var dom = $G(i);
        if (!dom) continue;
        var tagName = dom.tagName,
          content = lang["static"][i];
        if (content.src) {
   
          //clone
          content = utils.extend({
   }, content, false);
          content.src = langImgPath + content.src;
        }
        if (content.style) {
   
          content = utils.extend({
   }, content, false);
          content.style = content.style.replace(
            /url\s*\(/g,
            "url(" + langImgPath
          );
        }
        switch (tagName.toLowerCase()) {
   
          case "var":
            dom.parentNode.replaceChild(document.createTextNode(content), dom);
            break;
          case "select":
            var ops = dom.options;
                 for (var j = 0, oj; (oj = ops[j]); ) {
   
              oj.innerHTML = content.options[j++];
            }
            for (var p in content) {
   
              p != "options" && dom.setAttribute(p, content[p]);
            }
            break;
          default:
            domUtils.setAttributes(dom, content);
        }
      }
    });
  }
})();
