如何从电子中的新BrowserWindow()获取窗口对象? [英] How can I get a window object from new BrowserWindow() in electron?

问题描述

有没有一种方法可以重用窗口对象?可能有必要，因为各个窗口可能是动态生成的.

Is there a way to reuse the window object? It may be necessary because the respective window may be generated dynamically.

var electron = require('electron');
var app = electron.app
var BrowserWindow = electron.BrowserWindow

app.on('ready', function(){
  var win = new BrowserWindow();
  win.loadURL 'file://' + __dirname + '/index.html';

  // now i want use the window object in my BroserWindow win
 window = win.getWindowObject; // like this
  window.document.write(); // i can use window object here
});

推荐答案

仍然没有直接访问窗口对象的方法，但是方法

Still there isn't a way to directly access window object, however the method BrowserWindow.webContents.executeJavaScript allows to do it indirect:

let myWindow = new BrowserWindow(params);
myWindow.webContents.executeJavaScript('window.anyWantedProperty')
    .then(result => console.log(result));

如果通过用户输入，请小心，因为此方法允许代码注入.

Be careful if you pass user input as this method allow code injection.
