electron 子视图BrowserView

类似webview标签,可以用来替代webview标签

1、引入electron中的BrowserView
	const {app, BrowserWindow,BrowserView} = require('electron')
	
2、创建BrowserView实例
	  let view=new BrowserView();
	  
3、设置视图大小和位置
	  view.setBounds({x:10,y:20,width:300,height:300});
	  
4、设置视图加载的网页内容
	  view.webContents.loadURL('https://www.baidu.com');
	  
5、在父窗口内加载视图
	  mainWindow.setBrowserView(view);

其他方法
view.destroy();  销毁视图
view.isDestroyed();  返回布尔值,视图是否销毁
view.setBackgroundColor("#F5F5F5");   背景色,16进制rgba格式

文档

代码示例:

// Modules to control application life and create native browser window
const {app, BrowserWindow,BrowserView} = require('electron')
const path = require('path')

function createWindow () {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    //弹出的窗口有无边框,默认为有
    // frame:false,
    show:false,
    backgroundColor:'#586148',
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
      nodeIntegration:true,
      webviewTag:true
    },
  })

  // and load the index.html of the app.
  mainWindow.loadFile('index.html')
  mainWindow.webContents.on("did-finish-load",()=>{
      
  })
  mainWindow.webContents.on('dom-ready',()=>{
   
  })
  mainWindow.once('ready-to-show',function(){
    mainWindow.show();
  })
  
  let view=new BrowserView();
  view.setBounds({x:10,y:20,width:300,height:300});
  view.webContents.loadURL('https://www.baidu.com');
  mainWindow.setBrowserView(view);

  setTimeout(()=>{
    view.destroy()
  },5000)


  // Open the DevTools.
  // mainWindow.webContents.openDevTools()
}

// 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)
app.on('ready',()=>{

  createWindow();

});

// Quit when all windows are closed.
app.on('window-all-closed', function () {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q

  if (process.platform !== 'darwin') app.quit()
})

app.on('activate', function () {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (BrowserWindow.getAllWindows().length === 0) createWindow()
})

// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.
