How can I create a new modal BrowserWindow from a render process?
解决方案
You cannot use BrowserWindow in the renderer process. Only in the main process:
See https://www.electronjs.org/docs/api/browser-window#browserwindow
The two processes must communicate via a channel:
// main process
const {app, BrowserWindow, ipcMain} = require('electron')
app.whenReady().then(function () {
const mainWindow = new BrowserWindow({ webPreferences: { nodeIntegration: true } });
mainWindow.loadFile('index.html');
});
ipcMain.on('go!', (ev, url) => {
// ^^^^^
// A channel called "go!"
new BrowserWindow().loadURL(url);
});
// renderer process
const {ipcRenderer} = require('electron');
document.querySelector('button').addEventListener('click', function () {
ipcRenderer.send('go!', 'https://www.discogs.com/artist/7760-Japanese-Telecom');
});
<html>
<body>
<button>detroit techno</button>
<script>require('./renderer.js')</script>
</body>
</html>
When you click on the button "detroit techno" (as you should!):
- The renderer process sends a message with a url
- The main process picks up the message and open the url in a new window
