electron demo

Table of Contents

    electron demo实例 用electron框架做的一个demo程序,调用的数据来自showapi中的接口。

    1. 入口main.js 在app on ready回调中初始化菜单,主窗口,托盘,主页面index.html
    const electron = require('electron')
    const menuTemplate = require('./js/menu').template
    const trayTempl = require('./js/menu').trayTempl
    const path = require('path')
    const {app} = electron
    const {Menu} = electron
    const {BrowserWindow} = electron
    const {Tray} = electron
    const ipc = electron.ipcMain
    
    let win = null
    let tray = null
    
    function initMenu() {
        const menu = Menu.buildFromTemplate(menuTemplate)
        Menu.setApplicationMenu(menu)
    }
    
    function initWindow() {
      win = new BrowserWindow({width: 700, height: 600})
      win.loadURL(`file://${__dirname}/view/index.html`)
      // win.webContents.openDevTools();
    
      win.on('close', (event) => {
        console.log('close');
        if (process.platform != 'darwin') {
          event.preventDefault()
          win.hide()
        }
      })
    
      win.on('closed', () => {
        console.log('closed')
        win = null
      })
    }
    
    function initTray() {
      if (process.platform == 'darwin') {
        return;
      }
    
      const iconPath = path.join(__dirname, 'image', 'tray.ico')
      tray = new Tray(iconPath)
      tray.setToolTip('show api')
      tray.setContextMenu(Menu.buildFromTemplate(trayTempl))
      tray.on('click', () => {
        win.show()
      })
    }
    
    app.on('ready', () => {
      initMenu()
      initWindow()
      initTray()
    })
    
    app.on('window-all-closed', () => {
      console.log('window-all-closed')
      app.quit()
    })
    
    app.on('activate', () => {
      console.log('activate')
      if (win === null) {
        createWindow()
      } else {
        win.show()
      }
    })
    
    ipc.on('load_url', (event, url) => {
      if (win) {
        console.log(url)
        win.loadURL(url)
      }
    })
    
    
    1. 使用showapi协议获取数据,然后通过ejs render在html上展示
    'use strict';
    const ipc = require('electron').ipcRenderer
    const ejs = require('ejs')
    
    const funcList = [
      {

      }
    ]
    
    const html = ejs.render($('#func_list').html(), {funcList: funcList})
    $('.container').html(html)
    
    $('.func').click((e) => {
      const webName = $(e.target).closest('.func').attr('webName')
      ipc.send('load_url', `file://${__dirname}/../view/${webName}`)
    })
    
    
    1. 通过ipcRenderer与ipcMain与各页面之间通信

    ipcRenderer

    $('.func').click((e) => {
      const webName = $(e.target).closest('.func').attr('webName')
      ipc.send('load_url', `file://${__dirname}/../view/${webName}`)
    })
    

    ipcMain

    ipc.on('load_url', (event, url) => {
      if (win) {
        console.log(url)
        win.loadURL(url)
      }
    })
