如何从电子主进程中访问BrowserWindow Javascript全局？

问题描述

我想要一个菜单​​，在主进程中定义，在原子/电子应用程序的当前浏览器窗口中调用JS代码。

I want a menu, defined in the main process to call JS code inside the current browser window in an atom/electron application.

获取主进程全局变量浏览器窗口是

Getting main process globals form the browser window is

const remote = require('remote')
const foo    = remote.getGlobal('foo')

主进程的等价物（又名当前窗口全局变量）。这就是我想在伪代码中做的事情

What is the equivalent for the main process (aka get current window globals). This is what I want to do in pseudo-code

// JS inside main process
const BrowserWindow = require('browser-window')
//...
// Inside the menu callback
let window    = BrowserWindow.getFocusedWindow()
let commander = window.global('commander') /// <---- PSEUDO-CODE !!!
commander.handleCommand('File.Save')

推荐答案

是对您对webContents流程的评论的引用在api中，在注意：下遥控器。

Here is a reference to your comment about the webContents process in the api, in the "Note:" under remotes.

但是，如果你只想触发一个功能，你也可以使用和进程触发相应的代码运行。这样的东西...

However, if you just want to trigger a function, you could also use the webContents.send() and ipc(main process) processes to trigger the appropriate code to run. Something like this...

// JS inside main process
const window = require('electron').BrowserWindow;

ipc.on('menuItem-selected', function(){
    let focusedWindow    = window.getFocusedWindow();
    focusedWindow.webContents.send('file-save');
});

// Inside the menu callback
require('ipc').on('file-save', function() {
  // File save function call here
});

更新：

电子版0.35 .0及以上，ipc api更改为以下内容：

Update:

For Electron version 0.35.0 and above, the ipc api changed to the following:

// In main process.
const ipcMain = require('electron').ipcMain;

// In renderer process (web page).
const ipcRenderer = require('electron').ipcRenderer;
