1.效果
2.实现
2.1：先看我上一篇，这篇就是在上一篇的基础上添加一个手写功能，导入注册就行了
vue2使用wangeditor实现数学公式+富文本编辑器-CSDN博客
在components中添加myscriptMath.js
svg也就是个显示的图标，可以替换为其他
import $ from "jquery";
import { mathIcon } from "../assets/icons/svg-icon.ts";class MyScriptMathMenu {constructor() {this.title = "手写公式";this.iconSvg = mathIcon;this.tag = "button";this.showModal = true;this.modalWidth = 900;this.modalHeight = 500;}// 菜单是否需要激活（如选中加粗文本，“加粗”菜单会激活），用不到则返回 falseisActive(editor) {return false;}// 获取菜单执行时的 value ，用不到则返回空 字符串或 falsegetValue(editor) {return "";}// 菜单是否需要禁用（如选中 H1 ，“引用”菜单被禁用），用不到则返回 falseisDisabled(editor) {return false;}// 点击菜单时触发的函数exec(editor, value) {// Modal menu ，这个函数不用写，空着即可}// 弹出框 modal 的定位：1. 返回某一个 SlateNode； 2. 返回 null （根据当前选区自动定位）getModalPositionNode(editor) {return null; // modal 依据选区定位}// 定义 modal 内部的 DOM ElementgetModalContentElem(editor) {// panel 中需要用到的idconst inputIFrameId = "kityformula_" + Math.ceil(Math.random() * 10);const btnOkId = "kityformula-btn" + Math.ceil(Math.random() * 10);const $content = $(`<div><iframe id="${inputIFrameId}" class="iframe" height="400px" width="100%" frameborder="0" scrolling="no" src="/myscriptMath/index.html"></iframe></div>`);const $button = $(`<button id="${btnOkId}" class="right" style='margin: 5px 0'>确认插入</button>`);$content.append($button);$button.on("click", () => {// 执行插入公式const node = document.getElementById(inputIFrameId);const latex = node.contentWindow.latex;const formulaNode = {type: "paragraph",children: [{type: "formula",value: latex,children: [{text: "",},],},],};editor.insertNode(formulaNode);editor.hidePanelOrModal();});return $content[0]; // 返回 DOM Element 类型// PS：也可以把 $content 缓存下来，这样不用每次重复创建、重复绑定事件，优化性能}
}
const menuConf = {key: "myscriptMath", // menu key ，唯一。注册之后，需通过 toolbarKeys 配置到工具栏factory() {return new MyScriptMathMenu();},
};export default menuConf;
2.2导入注册实现
import myscriptMath from "@/components/myscriptMath";
import { Boot } from "@wangeditor/editor";toolbarConfig: {// 插入编辑公式菜单insertKeys: {index: 0,keys: ["kityFormula", // “编辑公式”菜单"myscriptMath",],},// excludeKeys: [ /* 隐藏哪些菜单 */ ],},created() {Boot.registerMenu(myscriptMath);},3.完整代码
