　　openWindow.jsweb

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



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

//渲染进程无法直接调用主进程中的模块，可是咱们能够经过 electron中的remote模块间接的调用主进程中的模块


btn.onclick=function(){
    // alert('点击了');


    ipcRenderer.send('openWindow');



    //经过localStorage实现页面传值

    var aid=123;

    localStorage.setItem('aid',aid);





}

new.jsnpm

//获取localStorage的数据


var aid=localStorage.getItem('aid');

console.log(aid);

引入到new.htmlelectron

ipcmain.jside

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


var path=require('path');


var win=null;

//接收到广播
ipcMain.on('openWindow',function(){


        
    //调用 BrowserWindow打开新窗口
    win=new BrowserWindow({

        width:400,
        height:300,

        // fullscreen:true
    })
    win.loadURL(path.join('file:',__dirname,'../news.html'));
    
    //开启新窗口的调试模式
    win.webContents.openDevTools();

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