我正在开发一个应用程序(带电子),我希望用户能够在按下“esc”时退出全屏模式.我尝试了不同的方法,徒劳无功.

以下是以全屏模式在新浏览器窗口中启动应用程序以及显示和

HTML / CSS内容的代码：

'use strict';

const electron = require('electron');

// Module to control application life.

const app = electron.app;

// Module to create native browser window.

const BrowserWindow = electron.BrowserWindow;

// 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({fullscreen:true});

// and load the index.html of the app.

mainWindow.loadURL('file://' + __dirname + '/index.html');

// 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;

});

}

// This method will be called when Electron has finished

// initialization and is ready to create browser windows.

app.on('ready',createWindow);

// 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();

}

});

app.on('activate',function () {

// 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 (mainWindow === null) {

createWindow();

}

});

这是我正在尝试添加到此代码,以便能够退出全屏但它不起作用：

app.on('keydown',function(e){

if(e.keyCode === 27){

app.exitFullscreen();

}

});

我也试过“cancelFullscreen”.而“全屏：假”.不工作.

非常感谢您的关注！
