相反，我在创建模态时需要帮助。使用此视频作为引用:

我遵循了本教程，但是我无法使按钮正常工作。我不知道问题出在哪里，这使我发疯。

我需要将他的javascript代码放在 Electron 元素的特定位置吗？帮助

Javascript 

const { app, BrowserWindow, Menu} = require('electron')
const path=require('path')
const url=require('url')

function createWindow () {
  // Create the browser window.
  const mainWin = new BrowserWindow({
    width: 800,
    height: 600,
    resizable:false,
    webPreferences: {
      nodeIntegration: true
    }
  })

  // and load the index.html of the app.
  mainWin.loadFile('index.html')

  // Open the DevTools.
        //win.webContents.openDevTools()

  var menu = Menu.buildFromTemplate([
      {
          label: "Menu",
          submenu: [
              {label: 'Exit',
                accelerator: process.platform == 'darwin' ? 'Command+Q' :
                'Ctrl+Q',
                click(){
                    app.quit();
                }
            }
          ]
      },
      {
          label: 'Classes',
          submenu: [
              {label: 'Add Classes'},
              {label: 'Manage Classes'}
          ]
      },
      {
          label: 'Reply Slips',
          submenu: [
              {label: 'Add Reply Slips'},
              {label: 'Manage Reply Slips'}
          ]
      }
  ])
  Menu.setApplicationMenu(menu);

  document.getElementById('addcBtn').addEventListener('click', function(){
    document.querySelector(".bg-modal").style.display = "flex";
  });

  document.querySelector('.close').addEventListener('click', function(){
    document.querySelector(".bg-modal").style.display = "none";
  });
}

// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.whenReady().then(createWindow)

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

app.on('activate', () => {
  if (BrowserWindow.getAllWindows().length === 0) {
    createWindow()
  }
})

请参阅视频制作者创建的javascript代码。甚至可以将该代码用于 Electron 元素吗？

最佳答案

显示对话框以选择多个文件的示例:

const { dialog } = require('electron')
console.log(dialog.showOpenDialog(
   { properties: ['openFile', 'multiSelections'] }))

对话框从Electron的主线程打开。如果要使用渲染器进程中的对话框对象，请记住使用 Remote 进行访问: 
const { dialog } = require('electron').remote
console.log(dialog)
