Mendix，在开发组件之前，需要了解的部分知识
2025年6月6日 11:17
环境安装
- node 环境，建议安装v18以上版本
- nodejs官网下载安装包，或通过nvm安装
node -v
- 全局安装yo
npm install -g yo
- 全局安装 @mendix/generator-widget
npm install -g @mendix/generator-widget
使用
- 初始化项目
yo @mendix/widget myWidget
- 进入组件目录并打包，将组件更新到mendix本地工程中
cd myWidget && npm run build
组件目录说明
- dist
- node_modules
- src
components
HelloWorldSample.tsx // 默认生成的子组件
ui
xxx.css // 可修改为 scss文件，
package.xml
xxx.editorConfig.ts // xml配置信息调整，比如某个xml字段的显示隐藏等操作
xxx.editorPreview.tsx // mendix预览模式下的展示内容
xxx.tsx // 组件渲染的内容文件
xxx.xml // 配置组件需要用到的参数信息
- typings
xxx.d.ts // xml文件配置的字段类型，自动生成的
xml配置项说明
<?xml version="1.0" encoding="utf-8" ?>

xml配置项的显示/隐藏方式
- 修改
xxx.editorConfig.ts文件import { xxxProps } from "../typings/xxx"; import { hidePropertyIn } from "@mendix/pluggable-widgets-tools"; // 新增依赖 // ... // ... // ... export function getProperties(_values: xxxProps, defaultProperties: Properties): Properties { // 主要代码 if (!_values.showCode) { hidePropertyIn(defaultProperties, _values, "code"); } if (!_values.isRequired) { hidePropertyIn(defaultProperties, _values, "errorText"); } return defaultProperties; }
组件参数说明
- 组件默认接收一个对象，默认参数在mendix中可配置且，包含有：
- name
- class
- style：非必传
- tabIndex：非必传
- 用法
import { ReactElement, createElement } from "react"; import classNames from "classnames"; import { xxxProps } from "../typings/xxxProps"; import "./ui/xxx.scss"; export function xxx(props: xxxProps): ReactElement { const { name, class: cls, style, tabIndex } = props; return ( <div className={classNames(cls, "v-test-wrap")} style={style}> <p>Container</p> </div> ); }
如需要用到mendix挂载在window上的mx方法，可在 typings 目录下添加 client.d.ts
declare namespace mx {
namespace ui {
type OpenForm2Function = ((
page: string,
dh: DisposeCallback,
title: string,
currentForm: any,
option: Option,
numberOfPagesToClose: number
) => Promise<any>) & { ["_tabRouter"]: boolean };
interface DisposeCallback {
[key: string]: { unsubscribe: () => void };
}
interface Option {
location: "content" | "popup" | "node";
domNode?: Element;
}
let openForm2: OpenForm2Function;
let getContentForm: any;
}
namespace data {
type saveDocument = (
guid: string,
name: string,
params: any,
blob: File,
callback: () => void,
errorCallback: (error: any) => void
) => Promise<void>;
type remove = (params: RemoveType) => Promise<void>;
interface RemoveType {
guid: string;
callback: () => void;
errorCallback: (error: any) => void;
}
type action = (
actionname: any,
applyto: any,
guids: any[],
params: any,
callback: (result: any) => void,
errorCallback: (error: any) => void
) => Promise<void>;
type callNanoflow = (
nanoflow: any,
context: mx.lib.MxContext,
origin: mx.lib.form._FormBase,
callback: (result: any) => void,
errorCallback: (error: any) => void
) => Promise<void>;
type create = (
entity: string,
callback: (guid: string) => void,
errorCallback: (error: any) => void
) => Promise<void>;
const action = action;
const callNanoflow = callNanoflow;
const saveDocument = saveDocument;
const remove = remove;
const create = create;
}
}
declare namespace mendix {
namespace lib {
class MxContext {
setTrackObject(obj: any): void;
}
}
interface Lang {
getUniqueId(): string;
}
let lang: Lang;
}
declare namespace dijit {
function getUniqueId(id: string): string;
}
declare namespace window {
namespace vRequestManager {
function request(url: string, options: any, requestId: string): Promise<any>;
function vCreateObjFn(obj: any): Promise<any>;
function cancelRequest(id: string): Promise<void>;
}
}
mendix工程，默认是不会生成 index.html 文件的，需要手动生成，方式如下
- mendix 菜单栏 App -> Show App Directory in Explorer
-
xxx/theme/web目录下，就是项目启动的入口文件所在位置 -
index.html文件内容<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8" /> <meta name="viewport" content="width=device-width, initial-scale=1.0" /> <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate" /> <meta http-equiv="Pragma" content="no-cache" /> <meta http-equiv="Expires" content="0" /> <meta name="referrer" content="no-referrer" /> <title>Mendix</title> <script type="text/javascript"> // 定义全局 hash globalThis.hash = Math.floor(Math.random() * 0xffffff).toString(16);
