在electron.js中打开文件

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

function createWindow() {
  const win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true
    }
  })

  // 加载你的应用的HTML文件
  win.loadFile('index.html')
}

app.whenReady().then(createWindow)

<input type="file" id="file-input">

const { ipcMain, dialog } = require('electron')

ipcMain.on('open-file-dialog', (event) => {
  dialog.showOpenDialog({
    properties: ['openFile']
  }).then(result => {
    // 发送所选文件的路径给渲染进程
    event.sender.send('selected-file', result.filePaths[0])
  }).catch(err => {
    console.log(err)
  })
})

const { ipcRenderer } = require('electron')

const fileInput = document.getElementById('file-input')

fileInput.addEventListener('click', () => {
  ipcRenderer.send('open-file-dialog')
})

ipcRenderer.on('selected-file', (event, path) => {
  // 在这里处理所选文件的路径
  console.log(path)
})
