VSCode 使用electron主进程调用js文件

1. package.json

{
    "name": "electrontest",
    "version": "0.1.0",
    "main": "main.js"
}

2.main.js

var electron = require('electron');
var app = electron.app;
var BrowserWindow = electron.BrowserWindow;
var ipc = electron.ipc;


var mainWindow = null;

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

app.on('ready', function () {
    // 创建浏览器窗口。
    mainWindow = new BrowserWindow({ width: 800, height: 600 });

    // 加载应用的 index.html
    mainWindow.loadURL('file://' + __dirname + '/index.html');

    // 打开开发工具
    mainWindow.openDevTools();

    // 当 window 被关闭，这个事件会被发出
    mainWindow.on('closed', function () {
        // 取消引用 window 对象，如果你的应用支持多窗口的话，
        // 通常会把多个 window 对象存放在一个数组里面，
        // 但这次不是。
        mainWindow = null;
    });

    mainWindow.webContents.openDevTools()
});

3.index.html

<!DOCTYPE html>
<html>

<head>
    <title>Hello World!</title>
</head>

<body>
    <script>
        var alertOnlineStatus = function () {
            //window.alert(navigator.onLine ? 'online' : 'offline');
            ipc.send('online-status-changed', navigator.onLine ? 'online' : 'offline');
        };

        window.addEventListener('online', alertOnlineStatus);
        window.addEventListener('offline', alertOnlineStatus);

        alertOnlineStatus();
    </script>
    <h1>Hello World!</h1>
    We are using io.js111
    <script>document.write(process.version)</script>
    and Electron
    <script>document.write(process.versions['electron'])</script>.
</body>

</html>
