web前端技术分享Electron之IPC 通信
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
本文由小千給大家分享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 processrequire('./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 = 1setInterval( () => {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
// Modulesconst {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 readyfunction createWindow () {mainWindow = new BrowserWindow({width: 1000, height: 800, x: 100, y:140,webPreferences: { nodeIntegration: true }})// Load index.html into the new BrowserWindowmainWindow.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 closedmainWindow.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 readyapp.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 BrowserWindowapp.on('activate', () => {if (mainWindow === null) createWindow()})希望本文的分享能幫到大家！本文來自千鋒教育，轉載請注明出處。
