因此，我有一个“开始”按钮，单击该按钮后，我希望它执行一个功能。
我知道我可以在启动 Electron 应用程序时执行该功能，但是无论如何要说有一个启动按钮，并且它在单击该按钮时执行代码？
我也知道您不能在浏览器中使用 Node ，我知道Electron使用 Chrome ，但是仍然可以访问 Node 吗？
这是我得到的错误:

Uncaught Exception:
ReferenceError: document is not defined
index.js 
    const { app, BrowserWindow, ipcMain } = require('electron');
const path = require('path');
const Bot = require('./bot')
// Handle creating/removing shortcuts on Windows when installing/uninstalling.
if (require('electron-squirrel-startup')) { // eslint-disable-line global-require
  app.quit();
}

const createWindow = () => {

  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true,
      preload: "./bot.js"
    }
  });

  // and load the index.html of the app.
  mainWindow.loadFile(path.join(__dirname, 'index.html'));

  // Open the DevTools.
  mainWindow.webContents.openDevTools();
};

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);

// Quit when all windows are closed, except on macOS. There, it's common
// for applications and their menu bar to stay active until the user quits
// explicitly with Cmd + Q.
app.on('window-all-closed', () => {
  if (process.platform !== 'darwin') {
    app.quit();
  }
});

app.on('activate', () => {
  // On OS X it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow();
  }
});

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and import them here.
这是bot.js文件: 
    const robot = require('robotjs')
const electron = require('electron')
const ipc = electron.ipcRenderer

const Bot = () => {

    const button = document.getElementById('start');
    button.addEventListener('click', () => console.log('Click'))
    // button.addEventListener('click', function (e) {
    //     // Get mouse position.
    //     var mouse = robot.getMousePos();

    //     // Get pixel color in hex format.
    //     var hex = robot.getPixelColor(mouse.x, mouse.y);
    //     console.log("#" + hex + " at x:" + mouse.x + " y:" + mouse.y);
    // });

}


module.exports = Bot;
index.html文件: 
    <!DOCTYPE html>
<html>
 <head>
  <meta charset="UTF-8" />
  <title>Hello World!</title>
  <link rel="stylesheet" href="index.css" />
 </head>
 <body>
  <div class="App">
   <div class="Header">
    <h1>Checkout-Bot</h1>
   </div>
   <div class="Wrapper">
    <p>Click Start</p>
    <button id="start">Start</button>
   </div>
  </div>
 </body>
</html>

最佳答案

将这行代码和Bot();从index.js移到index.html:

const Bot = require('./bot')
更改此: 
const mainWindow = new BrowserWindow({
  width: 800,
  height: 600,
});
对此: 
const mainWindow = new BrowserWindow({
  width: 800,
  height: 600,
  webPreferences: {
    nodeIntegration: true,
  }
});
