*2 The key is a dead key. The value of keyup event is 0xBA (186). *3 The key is a dead key. The value of keyup event is 0x10 (16). *4 No key events are fired. *5 The key isn't available with Greek keyboard layout (does not input any character). The value of keyup ...
If theKeyboardEventrepresents the press of adead key, the key value must be "Dead". Some specialty keyboard keys (such as the extended keys for controlling media on multimedia keyboards) don't generate key codes on Windows; instead, they triggerWM_APPCOMMANDevents. These events get mapped to...

document.addEventListener('keydown',function(event){letkey=event.key;if(key==='Enter'){console.log('你按下的是回车键～');}}); 上面的代码只是做一个示例,按键相关的属性有很多个,这些属性定义在 KeyboardEvent 这个接口中。keydown 事件监听函数接受的第一个参数 event 就实现了这个接口(event不仅仅实...
The migration of apps from the Universal Windows Platform (UWP) to the Windows App SDK (specifically, WinUI 3) might require a few changes in the way input keyboard events are handled, primarily due to the app model differences. This topic describes commonly identified differences....
The value of keyup event is 0x10 (16). *4 No key events are fired. *5 The key isn't available with Greek keyboard layout (does not input any character). The value of keyup event is 0x00 (0). Non-printable keys (function keys) keyCode values of each browser's keydown event ...

The key idea is that we can simulate keyboard event periodically to prevent screen saver ro run. The Windows API to simulate keyboard event is keybd_event: voidkeybd_event( BYTE bVk, BYTE bScan, DWORD dwFlags, ULONG_PTR dwExtraInfo
