我尝试使用modal.loadfile（
${__dirname}/pages/Company/login.html?id=1234） 但是出现错误 电子：无法加载URL：file：///users/excelgraphics/documents/regular%20jobs/oot/aux%20service/aux%20services/pages/newservice.html%3fid=1234带有错误：
const popupLogin = (htmlFile, parentWindow, width, height) => {
let modal = new BrowserWindow({
width: 600,
height: 500,
modal: true,
resizable: false,
icon: path.join(__dirname + '/public/auxwall/logos/favicon.png'),
parent: MainWindow,
frame: false,
webPreferences: {
preload: path.join(__dirname, 'preload.js'),
contextIsolation: false,
nodeIntegration: true,
}
})
modal.loadFile(`${__dirname}/pages/Company/login.html`)
return modal;
}
如何将一个从Mainwindow发送到Electron JS中的Childwindow的变量？但模态窗口无法从主进程访问消息
记住您的模态只是一个没有框架的窗口，可以通过使用
Inter-process Communication来回传递数据。要开始确保您的电子应用程序，您应该真正阅读
Context隔离id传递到新创建的窗口，请使用{window}.webcontents.send
加载页面后立即立即将login.html发送到窗口。
idconst popupLogin = (htmlFile, parentWindow, width, height) => {
// Get the customers id from whatever source necessary.
let id = 99;
// Create the window.
let modal = new BrowserWindow({
width: 600,
height: 500,
modal: true,
resizable: false,
icon: path.join(__dirname +
'/public/auxwall/logos/favicon.png'),
parent: MainWindow,
frame: false,
show: false, // Hide possible flash and DOM update(s).
webPreferences: {
preload: path.join(__dirname, 'preload.js'),
contextIsolation: true, // Set to true
nodeIntegration: true, // Node integration (removed in Electron v12)
}
})
// Load the window.
// Note: The loadFile() method returns a promise.
modal.loadFile(`${__dirname}/pages/Company/login.html`)
.then(() => { modal.webContents.send('login:id', id); })
.then(() => { modal.show(); }) // Now show the modal
return modal;
}
