        .content{

            width: 100%;

            height: 400px;

            background: orange;


            overflow-y: auto;

<body>
       
    <button id="btn">
        打开新窗口
    </button>
    

    <script src="renderer/openWindow.js"></script>   

</body>
</html>

　　openWindow.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');


    ipcRenderer.send('openWindow');



    //通过localStorage实现页面传值

    var aid=123;

    localStorage.setItem('aid',aid);





}

new.js

//获取localStorage的数据


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

console.log(aid);

引入到new.html

ipcmain.js

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,
        // frame:false,
        // 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',()=>{

        win=null;
    })


})
