Question

下面的代码只是使用电子节点模块显示对话框。

app.js

    const { dialog } = require('electron')
    const response = dialog.showMessageBox(null);
    console.log(response);

需要帮助以了解为什么我得到以下错误消息：

    const response = dialog.showMessageBox(null);
                            ^
    TypeError: Cannot read property 'showMessageBox' of undefined
        at Object.<anonymous> (C:\Users\1217688\Desktop\WebApp\node-elect-test\app.js:2:25)
        at Module._compile (module.js:660:30)

Answer 1

在渲染器过程中，添加.remote

const { dialog } = require('electron').remote

Answer 2

尝试在应用就绪后调用对话框模块：

app.on('ready', () => {
  const { dialog } = require('electron')
  dialog.showMessageBox(null);
})

TypeError：无法读取节点js中未定义电子的属性'showMessageBox'
