无法更改默认电子菜单上的元素

Question

我有主菜单，因为它在每个电子应用程序上默认运行。我想更改它的内容并添加它想要的内容。因此，我尝试遵循此文档 http://electron.atom.io/docs/v0.36.0/api/menu/

因此，index.js 中我的 Hello World 应用程序代码如下：

'use strict';

const electron = require('electron');
const app = electron.app;  // Module to control application life.
const BrowserWindow = electron.BrowserWindow;  // Module to create native browser window.
const remote = require('electron').remote;
const Menu = remote.Menu;
const MenuItem = remote.MenuItem;

// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
var mainWindow = null;

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

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
app.on('ready', function() {
  // Create the browser window.
  mainWindow = new BrowserWindow({
    width: 800,
    height: 600

  });

  var template = [
    {
      label: 'Edit',
      submenu: [
        {
          label: 'Undo',
          accelerator: 'CmdOrCtrl+Z',
          role: 'undo'
        },
        {
          label: 'Redo',
          accelerator: 'Shift+CmdOrCtrl+Z',
          role: 'redo'
        },
        {
          type: 'separator'
        },
        {
          label: 'Cut',
          accelerator: 'CmdOrCtrl+X',
          role: 'cut'
        },
        {
          label: 'Copy',
          accelerator: 'CmdOrCtrl+C',
          role: 'copy'
        },
        {
          label: 'Paste',
          accelerator: 'CmdOrCtrl+V',
          role: 'paste'
        },
        {
          label: 'Select All',
          accelerator: 'CmdOrCtrl+A',
          role: 'selectall'
        },
      ]
    },
    {
      label: 'View',
      submenu: [
        {
          label: 'Reload',
          accelerator: 'CmdOrCtrl+R',
          click: function(item, focusedWindow) {
            if (focusedWindow)
              focusedWindow.reload();
          }
        },
        {
          label: 'Toggle Full Screen',
          accelerator: (function() {
            if (process.platform == 'darwin')
              return 'Ctrl+Command+F';
            else
              return 'F11';
          })(),
          click: function(item, focusedWindow) {
            if (focusedWindow)
              focusedWindow.setFullScreen(!focusedWindow.isFullScreen());
          }
        },
        {
          label: 'Toggle Developer Tools',
          accelerator: (function() {
            if (process.platform == 'darwin')
              return 'Alt+Command+I';
            else
              return 'Ctrl+Shift+I';
          })(),
          click: function(item, focusedWindow) {
            if (focusedWindow)
              focusedWindow.toggleDevTools();
          }
        },
      ]
    },
    {
      label: 'Window',
      role: 'window',
      submenu: [
        {
          label: 'Minimize',
          accelerator: 'CmdOrCtrl+M',
          role: 'minimize'
        },
        {
          label: 'Close',
          accelerator: 'CmdOrCtrl+W',
          role: 'close'
        },
      ]
    },
    {
      label: 'Help',
      role: 'help',
      submenu: [
        {
          label: 'Learn More',
          click: function() { require('electron').shell.openExternal('http://electron.atom.io') }
        },
      ]
    },
  ];

  if (process.platform == 'darwin') {
    var name = require('electron').app.getName();
    template.unshift({
      label: name,
      submenu: [
        {
          label: 'About ' + name,
          role: 'about'
        },
        {
          type: 'separator'
        },
        {
          label: 'Services',
          role: 'services',
          submenu: []
        },
        {
          type: 'separator'
        },
        {
          label: 'Hide ' + name,
          accelerator: 'Command+H',
          role: 'hide'
        },
        {
          label: 'Hide Others',
          accelerator: 'Command+Shift+H',
          role: 'hideothers'
        },
        {
          label: 'Show All',
          role: 'unhide'
        },
        {
          type: 'separator'
        },
        {
          label: 'Quit',
          accelerator: 'Command+Q',
          click: function() { app.quit(); }
        },
      ]
    });
    // Window menu.
    template[3].submenu.push(
      {
        type: 'separator'
      },
      {
        label: 'Bring All to Front',
        role: 'front'
      }
    );
  }

  menu = Menu.buildFromTemplate(template);
  Menu.setApplicationMenu(menu);
  // and load the index.html of the app.
  mainWindow.loadURL('file://' + __dirname + '/index.html');

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

  // Emitted when the window is closed.
  mainWindow.on('closed', function() {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    mainWindow = null;
  });
});

但是这里报错：

const Menu = remote.Menu;

App threw an error when running [TypeError: Cannot read property 'Menu' of undefined]

Answer 1

菜单的代码不应该在这里。远程模块将在 "front".

上使用

一个 Electron 应用程序分为主进程运行和 node.js（您的 index.js 脚本）和前端应用程序的 html 和 js。

在此示例中，应在链接到您的 index.html 文件的脚本中调用远程模块。

这篇link解释了如何获取原始默认菜单。 [在此处输入 link 描述][1] [1]: https://www.npmjs.com/package/electron-default-menu 从那里您可以追加您想要的新菜单项。

import electron from 'electron';
const defaultMenu = require('electron-default-menu');
const { Menu, app, shell } = electron;
const dialog = require('dialog');
 
app.on('ready', () => {
 
  // Get template for default menu 
  const menu = defaultMenu(app, shell);
 
  // Add custom menu 
  menu.splice(4, 0, {
    label: 'Custom',
    submenu: [
      {
        label: 'Do something',
        click: (item, focusedWindow) => {
          dialog.showMessageBox({message: 'Do something', buttons: ['OK'] })
        }
      }
    ]
  })
 
  // Set top-level application menu, using modified template 
  Menu.setApplicationMenu(Menu.buildFromTemplate(menu));
})
