ipcmain.jshtml

var {ipcMain,BrowserWindow} =require('electron');


var path=require('path');

var win=null;

//接收到廣播
ipcMain.on('openWindow',function(event,aid){
        


    //調用 BrowserWindow打開新窗口
    win=new BrowserWindow({

        width:400,
        height:300,
        webPreferences:{
            nodeIntegration: true
        }
    })
    win.loadURL(path.join('file:',__dirname,'../news.html'));
    
    //開啓新窗口的調試模式
    win.webContents.openDevTools();


    //經過win.webContents.send把當前數據廣播給 news進程

    win.webContents.on('did-finish-load',function(){

        win.webContents.send('toNews',aid);
    })






    win.on('closed',()=>{

        win=null;
    })


})

new.jsnode

//獲取localStorage的數據
var {ipcRenderer} =require('electron');


ipcRenderer.on('toNews',function(event,aid){

    console.log(aid);
})

openwidow.jsweb

var {ipcRenderer} =require('electron');



var btn=document.querySelector('#btn');

//渲染進程無法直接調用主進程中的模塊，可是咱們能夠經過 electron中的remote模塊間接的調用主進程中的模塊


btn.onclick=function(){
    // alert('點擊了');



    var aid='123456';

    ipcRenderer.send('openWindow',aid);
