主要用到了js 里面的 window.opener.postMessage(); 在html页可以直接运行，跟electron没有直接关系
1、新建父窗口页“06父窗口接收子窗口.html”
1 <!DOCTYPE html>
2 <html lang="en">
3 <head>
4 <meta charset="UTF-8">
5 <meta http-equiv="X-UA-Compatible" content="IE=edge">
6 <meta name="viewport" content="width=device-width, initial-scale=1.0">
7 <title>Document</title>
8 </head>
9 <body>
10 <input type="button" id="btn" value="打开子窗口" />
11 <span id="txt"></span>
12 <script>
13 let btn = document.getElementById("btn");
14 btn.onclick = (e)=>{
15 window.open('./06子窗口向父窗口传参数.html');
16 }
17
18 window.addEventListener('message',(msg)=>{ //监听子窗口传递过来的参数
19 let txt = document.getElementById("txt");
20 //txt.innerHTML = JSON.stringify(msg);
21 txt.innerHTML = msg.data; //展示传递过来的信息
22 })
23 </script>
24 </body>
25 </html>

2、新建子窗口页“06子窗口向父窗口传参数.html”
1 <!DOCTYPE html>
2 <html lang="en">
3 <head>
4 <meta charset="UTF-8">
5 <meta http-equiv="X-UA-Compatible" content="IE=edge">
6 <meta name="viewport" content="width=device-width, initial-scale=1.0">
7 <title>Document</title>
8 </head>
9 <body>
10 <h1>子窗口用来向父窗口传递参数</h1>
11 <input type="button" id="btn" value="向父窗口传递信息" />
12 <script>
13 let btn = document.getElementById("btn");
14 btn.onclick = (e)=>{
15 window.opener.postMessage('子窗口传递过来的参数'); //传递参数
16 }
17 </script>
18 </body>
19 </html>

3、执行命令
.\node_modules\.bin\electron .
4、运行效果：
