如何将值作为参数从节点 js 文件发送到电子 main.js 文件的 loadURL()？

Question

const electron = require("electron");
const { app, BrowserWindow } = electron;
const path = require("path");
​
function createWindow() {
  // Create the browser window.
​
  //window 1
  let win1 = new BrowserWindow({
    width: 1000,
    height: 600,
  });
​
  win1.loadURL("https://twitter.com/");
  win1.on("closed", () => {
    win1 = null;
  });
}
app.on("ready", createWindow);

i need to get url from frontend and access in node.js and pass to main.js loadURL() as a parameter.

What do you mean by this get url from frontend and access in node.js. If my recognition is correct, I think you are going to read url from the renderer and send this to Electron main process to create BrowserWindow based on that url. So communication between renderer and main. Use this ipcRenderer and ipcMain . You can send the url using ipcRenderer like this

...
    const { ipcRenderer } = require('electron');

    function sendUrlToMain(url) {
      ipcRenderer.sendSync('sendUrlToMain', url);
      return res;
    }
...

Then add this to main.js

ipcMain.on('sendUrlToMain',(event, arg) => {
let win1 = new BrowserWindow({
    width: 1000,
    height: 600,
  });
​
  win1.loadURL(arg);
  win1.on("closed", () => {
    win1 = null;
  });
});
