本文由小千给大家分享Electron之IPC 通信。
1、index.html
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<meta http-equiv="Content-Security-Policy" content="script-src 'self' 'unsafe-inline'">
<title>Hello World!</title>
</head>
<body>
<h1>Hello World!</h1>
<button type="button" id="talk">Talk to main process</button><br>
<!-- All of the Node.js APIs are available in this renderer process. -->
We are using Node.js <strong><script>document.write( process.versions.node)</script></strong>,
and Electron <strong><script>document.write( process.versions.electron )</script></strong>.
<script>
// You can also require other files to run in this process
require('./renderer.js')
</script>
</body>
</html>
2、renderer.js
// This file is required by the index.html file and will
// be executed in the renderer process for that window.
// All of the Node.js APIs are available in this process.
const { ipcRenderer } = require('electron')
let i = 1
setInterval( () => {
console.log(i)
i++
}, 1000)
document.getElementById('talk').addEventListener('click', e => {
// ipcRenderer.send( 'channel1', 'Hello from main window')
let response = ipcRenderer.sendSync( 'sync-message', 'Waiting for response')
console.log(response)
})
ipcRenderer.on( 'channel1-response', (e, args) => {
console.log(args)
})
ipcRenderer.on( 'mailbox', (e, args) => {
console.log(args)
})
3、main.js
// Modules
const {app, BrowserWindow, ipcMain} = require('electron')
// 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
// Create a new BrowserWindow when `app` is ready
function createWindow () {
mainWindow = new BrowserWindow({
width: 1000, height: 800, x: 100, y:140,
webPreferences: { nodeIntegration: true }
})
// Load index.html into the new BrowserWindow
mainWindow.loadFile('index.html')
// Open DevTools - Remove for PRODUCTION!
mainWindow.webContents.openDevTools();
mainWindow.webContents.on( 'did-finish-load', e => {
// mainWindow.webContents.send( 'mailbox', {
// from: 'Ray',
// email: 'ray@stackacademy.tv',
// priority: 1
// })
})
// Listen for window being closed
mainWindow.on('closed', () => {
mainWindow = null
})
}
ipcMain.on( 'sync-message', (e, args) => {
console.log(args)
setTimeout( () => {
e.returnValue = 'A sync response from the main process'
}, 4000)
})
ipcMain.on( 'channel1', (e, args) => {
console.log(args)
e.sender.send( 'channel1-response', 'Message received on "channel1". Thank you!')
})
// Electron `app` is ready
app.on('ready', createWindow)
// Quit when all windows are closed - (Not macOS - Darwin)
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') app.quit()
})
// When app icon is clicked and app is running, (macOS) recreate the BrowserWindow
app.on('activate', () => {
if (mainWindow === null) createWindow()
})
