Question

嘿我正在尝试将解析后的数据添加到表中，但由于某种原因它没有被添加仍在学习所以我真的不知道为什么我尝试搜索找不到任何东西

main.js：

const {app, BrowserWindow} = require('electron');

let win;


app.on('ready', () => {
    win = new BrowserWindow({width: 1280, height: 1080});
    win.loadURL(`file://${__dirname}/index.html`);
    //win.setMenu(null);
    win.webContents.openDevTools();

    win.on('closed', () => {
        win = null
    })
});

// Quit when all windows are closed.
app.on('window-all-closed', () => {
    if (process.platform !== 'darwin') {
        app.quit()
    }
});
