Yep! your logger is undefined because in that module all you did was declaring it as var and never created a logger before calling it like that: var logger = require('./logger-handler').logger; You need to initialize it first before calling it so something like that would work: import {createLogger, logger} from './logger-handler'; //init your logger with the service name - based on whatever you wrote, so not too sure - createLogger("enter the service"); //now your logger is ready to be used logger.log('info', 'all done'); Also, your createlogger function does not need to return a logger. 标签： htmlobjectpdf 解决方案 使用iframe 标记而不是对象标记，因为对象标记将被弃用。 因为 1-object 标签不能可靠地跨浏览器工作。 2-对象标签已弃用。不适用于新网站。 iframe 标签的语法： <iframe src="https://www.w3schools.com" title="W3Schools Free Online Web Tutorials"></iframe> 使用 iframe 标签时的提示： 提示 1：使用 CSS 设置 iframe 样式。 提示 2：最好始终包含iframe的标题属性。屏幕阅读器使用它来读取iframe的内容。 什么时候应该选择 IFrame？ 1- 提供您需要的安全性。 2-不阻止渲染。 希望它可能会有所帮助。 推荐阅读 c# - 在datagridview中过滤后显示原始rowindexruby-on-rails - Rails 应用程序在负载过重时不断崩溃php - 删除特定单词之前的所有单词android - 如何在 viewpager 中添加意图bash - 将 bash 函数自动添加到 $PATH 或 bash shelljavascript - 使用上一个/下一个按钮时更改活动选项卡颜色laravel - Laravel.log 文件不更新日志mysql - 如何将一个 Mysql 行显示为多行？json - 将特定 API 数据写入 JSON 文件javascript - 对象作为 React 子对象无效（发现：[object Promise]）Google Maps
