Electron.js 面试题与答案
问题 16. How can you handle file dialogs in Electron?
Electron provides the 'dialog' module for handling file dialogs. Developers can use methods like 'showOpenDialog' and 'showSaveDialog' to display file selection and save dialogs, respectively.
问题 17. Explain the role of the 'BrowserView' module in Electron.
'BrowserView' is used to embed web content within a window in Electron. It allows developers to create separate views within a single window, each with its own 'webContents' and lifecycle.
问题 18. How does Electron support multi-window applications?
Electron enables the creation of multiple windows in an application. Each window runs in its own renderer process, providing isolation. Developers can manage these windows using the 'BrowserWindow' module.
问题 19. What is the purpose of 'app.on('will-quit', callback)' in Electron?
The 'will-quit' event is emitted before the application is about to quit. Developers can use this event to perform cleanup tasks or prevent the application from quitting by calling 'event.preventDefault()'.
问题 20. Explain the 'webPreferences' option in the 'BrowserWindow' module.
The 'webPreferences' option allows developers to configure various preferences for the web page content, including enabling Node.js integration, setting the preload script, and controlling context isolation.
