主要用到了js 裡面的 window.opener.postMessage(); 在html頁可以直接執行,跟electron沒有直接關係
1、新建父視窗頁“06父視窗接收子視窗.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" contentView Code="width=device-width, initial-scale=1.0"> 7 <title>Document</title> 8 </head> 9 <body> 10 <input type="button" id="btn" value="開啟子視窗" /> 11 <span id="txt"></span> 12 <script> 13 let btn = document.getElementById("btn"); 14 btn.onclick= (e)=>{ 15 window.open('./06子視窗向父視窗傳引數.html'); 16 } 17 18 window.addEventListener('message',(msg)=>{ //監聽子視窗傳遞過來的引數 19 let txt = document.getElementById("txt"); 20 //txt.innerHTML = JSON.stringify(msg); 21 txt.innerHTML = msg.data; //展示傳遞過來的資訊 22 }) 23</script> 24 </body> 25 </html>
2、新建子視窗頁“06子視窗向父視窗傳引數.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>子視窗用來向父視窗傳遞引數</h1> 11 <input type="button" id="btn" value="向父視窗傳遞資訊" /> 12 <script> 13 let btn = document.getElementById("btn"); 14 btn.onclick = (e)=>{ 15 window.opener.postMessage('子視窗傳遞過來的引數'); //傳遞引數 16 } 17 </script> 18 </body> 19 </html>View Code
3、執行命令
.\node_modules\.bin\electron .
4、執行效果:
