electron JQ老项目退出进程
1.要在main.js里引入
const electron = require('electron')
const ipc = electron.ipcMain
在main.js里定义关闭前提是要在创建mainWindow对象后定义
ipc.on('window-close', function () {
mainWindow.close();
})
2.在页面中自定义一个按钮
var ipc = require('electron').ipcRenderer;
document.getElementById('colse').addEventListener('click', function() {
ipc.send('window-close');
})
3.报错的require未定义要设置 nodeIntegration: true,
function createWindow () {
// Create the browser window.
mainWindow = new BrowserWindow({
width: 3840,
height: 2160,
frame: false,
fullscreen: true,
webPreferences: {
preload: path.join(__dirname, 'preload.js'),
nodeIntegration: true,
}
})
完整main.js代码
// Modules to control application life and create native browser window
const {app, BrowserWindow} = require('electron')
const path = require('path')
const electron = require('electron')
const ipc = electron.ipcMain
// 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.
let mainWindow
function createWindow () {
// Create the browser window.
mainWindow = new BrowserWindow({
width: 3840,
height: 2160,
frame: false,
fullscreen: true,
webPreferences: {
preload: path.join(__dirname, 'preload.js'),
nodeIntegration: true,
}
})
// and load the index.html of the app.
mainWindow.loadFile('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
})
}
ipc.on('window-close', function () {
mainWindow.close();
})
// 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.
app.on('window-all-closed', function () {
// On macOS it is common for applications and their menu bar
// to stay active until the user quits explicitly with Cmd + Q
mainWindow = null;
app.exit();
if (process.platform !== 'darwin') app.quit()
})
app.on('activate', function () {
// On macOS 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 (mainWindow === null) 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 require them here.
