示例概述

¥Examples Overview

在本节中，我们收集了一组有关你可能想要在 Electron 应用中实现的常见功能的指南。每个指南都包含一个最小的、独立的示例应用中的实际示例。运行这些示例的最简单方法是下载 Electron Fiddle。

¥In this section, we have collected a set of guides for common features that you may want to implement in your Electron application. Each guide contains a practical example in a minimal, self-contained example app. The easiest way to run these examples is by downloading Electron Fiddle.

安装 Fiddle 后，你可以按 "在 Fiddle 中打开" 按钮，你将找到如下代码示例：

¥Once Fiddle is installed, you can press on the "Open in Fiddle" button that you will find below code samples like the following one:

docs/fiddles/quick-start (30.0.6)Open in Fiddle

main.js
preload.js
index.html

const { app, BrowserWindow } = require('electron/main')
const path = require('node:path')

function createWindow () {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js')
    }
  })

  win.loadFile('index.html')
}

app.whenReady().then(() => {
  createWindow()

  app.on('activate', () => {
    if (BrowserWindow.getAllWindows().length === 0) {
      createWindow()
    }
  })
})

app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit()
  }
})

window.addEventListener('DOMContentLoaded', () => {
  const replaceText = (selector, text) => {
    const element = document.getElementById(selector)
    if (element) element.innerText = text
  }

  for (const type of ['chrome', 'node', 'electron']) {
    replaceText(`${type}-version`, process.versions[type])
  }
})
