About this extension
防止网页检测到页面切换到后台,避免触发切屏警告
Read the publisher’s full description
此扩展程序通过底层注入和 API 拦截技术,使网页的焦点切换检测机制完全失效。启用后,该扩展程序会拦截所有页面焦点变化事件,阻止其向业务逻辑层传播。具体而言,该扩展程序会拦截并阻止以下核心 API 的调用和反馈: 可见性 API:对 visibilitychange 事件的 document.addEventListener 监听器完全被屏蔽,这使得页面无法通过 document.hidden 或 document.visibilityState 获取实际的可见性状态。 页面焦点事件:与窗口激活状态相关的事件(如失去焦点、获得焦点和页面隐藏)被拦截,导致页面无法检测用户是否已离开当前标签页。 性能监控接口:一些高级检测脚本通过分析 requestAnimationFrame 的调用频率或从性能 API 获取的时间差来确定页面是否在后台运行。该扩展程序通过算法模拟正常频率,完全消除了此类侧信道检测。 通过这种多层拦截机制,网页完全失去了感知窗口状态变化的能力。因此,所有基于切换检测的防作弊措施、警告提示或计时器暂停逻辑都无法被触发,从而提供了无缝的切换体验。
