ElectronJS:未被捕获的TypeError:无法读取属性"BrowserWindow"/"getCurrentWindow"未定义 [英] ElectronJS: Uncaught TypeError: Cannot read property "BrowserWindow" / "getCurrentWindow" of undefined
问题描述
首先，我知道这只是一个初学者会问的问题，但是在经历了50多种不同的解决方案，卸载npm和安装yarn之后，我不得不问这个令人难以置信的愚蠢问题.为什么不起作用?我想使用ElectronJS实现一个简单的标题栏，我遇到的问题是按钮(关闭/最小化/最大化)不起作用.我收到的错误如下:
First of all, I know that this is a question only a beginner would ask, but after going through more than 50 different solutions, uninstalling npm and installing yarn I have to ask this incredible dumb question. Why doesnt this work? I want to implement a simple titlebar using ElectronJS, the problem that I have is that the buttons (Close / Minimize / Maximize) do not work. The errors that I receive are the following:
最小化错误: titlebar.js:16未捕获的TypeError:无法读取HTMLButtonElement.maximizeApp(titlebar.js:16)上未定义的属性'BrowserWindow'
最大化错误: titlebar.js:16未捕获的TypeError:无法读取HTMLButtonElement.maximizeApp(titlebar.js:16)上未定义的属性"BrowserWindow"
退出错误: titlebar.js:21未捕获的TypeError:无法读取HTMLButtonElement.quitApp(titlebar.js:21)上未定义的属性'getCurrentWindow'
我用来控制它的JavaScript文件称为titlebar.js.就是这样:
The JavaScript file that I use to control this is called titlebar.js. This is it:
const remote_v = require("electron").remote;
var minimize_v = document.getElementById("minimize");
var maximize_v = document.getElementById("maximize");
var quit_v = document.getElementById("quit");
minimize_v.addEventListener("click",minimizeApp);
maximize_v.addEventListener("click",maximizeApp);
quit_v.addEventListener("click",quitApp);
function minimizeApp(){
remote_v.BrowserWindow.getFocusedWindow().minimize();
}
function maximizeApp(){
remote_v.BrowserWindow.getFocusedWindow().maximize();
}
function quitApp(){
remote_v.getCurrentWindow().close();
}
由于针对此类其他问题的许多修复程序都在渲染过程中，因此这是HTML文件:
Since many of the fixes for other problems like this is in the render process, this is the HTML File:
<!DOCTYPE html>
<head>
<title>Visionizer</title>
<link rel="stylesheet" href="css/editor.css">
<link rel="stylesheet" href="css/titlebar.css" >
</head>
<body>
<div class="container">
<div class="titlebar titlebarStyle">
<div class="windowTitle"> Visionizer </div>
<div class="windowControls windowControlsStyle">
<button id="minimize">-</button>
<button id="maximize">[]</button>
<button id="quit">x</button>
</div>
</div>
<div class="editorScreen">
</div>
</div>
<script src="js/titlebar.js"></script>
</body>
</html>
关于这件事的怪异之处是，经过大量尝试，我决定从github的教程中复制代码，我认为我的代码中可能有一个错误，我看不见.它仍然没有运行.我用 npm 卸载了该软件包，并使用 yarn global add electro @ latest 用 yarn 安装了该软件包，因为有人建议这样做.
The weird thing about this is that, after much trying, I decided to copy the code from the tutorial from github, I thought that there may have been an error in my code that I was too dumb to see. It still didn't run. I uninstalled the package with npm and installed it with yarn using yarn global add electron@latest since some people suggested this.
我根本不知道这是否很重要，但是我也将从下面的main.js文件中复制代码，因为我想确保自己包括了所有内容:
I do not know whether this is important at all, but I will also copy my code from the main.js-file below since I want to be sure that I included everything:
const { app, BrowserWindow } = require('electron')
function createWindow () {
const win = new BrowserWindow({
width: 900,
height: 800,
minHeight: 650,
minWidth: 600,
frame: false,
webPreferences: {
nodeIntegration: true
}
})
win.loadFile('editor.html')
win.webContents.openDevTools()
}
app.whenReady().then(createWindow)
app.on('window-all-closed', () => {
if (process.platform !== 'darwin') {
app.quit()
}
})
app.on('activate', () => {
if (BrowserWindow.getAllWindows().length === 0) {
createWindow()
}
})
这是package.json文件:
And here is the package.json file:
{
"dependencies": {
"electron": "^11.0.2"
},
"name": "*******",
"version": "1.0.0",
"description": "**********",
"main": "main.js",
"scripts": {
"start": "electron ."
},
"author": "************",
"license": "MIT"
}
互联网上的一些问题被回答为该项目启动错误，我听从了他们的建议，我使用 yarn start 命令启动项目
Some questions on the internet were answered by saying that the project was started wrongly, I followed their advice, I start my projects using the yarn start command
感谢您阅读本章.
推荐答案
您的远程模块似乎是 undefined .
您要设置 enableRemoteModule:true 在主窗口的 webPreferences 中，或者更好的是，完全删除 remote 并从主进程中执行这些操作.
You'd want to set enableRemoteModule: true in your main window's webPreferences, or better yet, scrap remote altogether and do these operations from the main process.
The remote module was disabled in Electron 10.
