Electron通过 BrowserWindow 和 webContents 模块实现渲染进 程和渲染进程的通信

ipcmain.js

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


var path=require('path');

var win=null;

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


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

        width:400,
        height:300,
        webPreferences:{
            nodeIntegration: true
        }
    })
    win.loadURL(path.join('file:',__dirname,'../news.html'));
    
    //开启新窗口的调试模式
    win.webContents.openDevTools();


    //通过win.webContents.send把当前数据广播给 news进程

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

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






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

        win=null;
    })


})

new.js

//获取localStorage的数据
var {ipcRenderer} =require('electron');


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

    console.log(aid);
})

openwidow.js

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



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

//渲染进程没法直接调用主进程中的模块，但是我们可以通过 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');



    var aid='123456';

    ipcRenderer.send('openWindow',aid);



}

new.js
