我正在使用 Electron 团队提供的样板 here .主进程正在运行,但是当我使用渲染器进程创建一个新窗口时,它给出了这个错误
Uncaught TypeError: electron_1.BrowserWindow is not a constructor
at HTMLButtonElement
正如我所搜索的那样,这是因为 .remote
在编译的 typescript 到 javascript 中不存在。代码是
main.ts:
import { app, BrowserWindow } from "electron";
import * as path from "path";
let mainWindow: Electron.BrowserWindow;
function createWindow() {
// Create the browser window.
mainWindow = new BrowserWindow({
height: 600,
width: 800,
});
// and load the index.html of the app.
mainWindow.loadFile(path.join(__dirname, "../index.html"));
// Open the DevTools.
// mainWindow.webContents.openDevTools();
// Emitted when the window is closed.
mainWindow.on("closed", () => {
// Dereference the window object, usually you would store windows
// in an array if your app supports multi windows, this is the time
// when you should delete the corresponding element.
mainWindow = null;
});
}
// 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.on("ready", createWindow);
// Quit when all windows are closed.
app.on("window-all-closed", () => {
// On OS X 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", () => {
// On OS X 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 (mainWindow === null) {
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.
renderer.ts:
// This file is required by the index.html file and will
// be executed in the renderer process for that window.
// All of the Node.js APIs are available in this process.
import { BrowserWindow } from "electron";
import * as path from "path";
let childWindow: Electron.BrowserWindow;
const newWindowBtn = document.getElementById('new-window');
newWindowBtn.addEventListener('click', (event) => {
const modalPath = path.join('file://', __dirname, '../modal.html');
childWindow = new BrowserWindow({ width: 400, height: 320 });
childWindow.on('close', () => { childWindow = null; });
childWindow.loadURL(modalPath);
childWindow.show();
});
当我尝试不将 typescript 代码编译为 javascript 并直接使用 .remote
运行时,它起作用了。
那么如何处理 typescript 代码呢?
最佳答案
我遇到了同样的问题。
使用 npm 安装快速入门并启动它时,会创建一个名为“Dist”的文件夹。该文件夹中有一个 renderer.js 文件。这是将 TypeScript 渲染器文件编译成 JS 的地方。
在我的 index.html 中,我改变了
<script>
require('./src/renderer.ts')
</script>
致
<script>
require('./dist/renderer.js')
</script>
瞧!有效。
我不确定为什么,但是没有一个 Electron Typescript Guides 能正常工作,因为 renderer.ts 没有被编译,并且在运行时需要,并且 Github 上有一个 Unresolved 问题(已经存在几个月了)没有回复。 好吧,这是我的解决方法。我不知道这会导致任何负面影响。
