推荐答案
如果您的目标是实现sendKeys函数(将击键直接发送到键盘缓冲区的函数)的浏览器模拟，那么您将无法实现这.在浏览器中触发按键事件会将事件发送到DOM处理程序，而不是键盘缓冲区.因此，要在浏览器中模拟实际的工作键盘并将笔画发送到键盘缓冲区是不可能的，而这不会造成浏览器进入操作系统的安全漏洞.
If your goal is to achieve a browser analog of a sendKeys function (a function where you send keystrokes directly to the keyboard buffer) then you will be unable to achieve this. Triggering key events in a browser sends events to DOM handlers not the keyboard buffer. For this reason simulating an actual working keyboard in the browser which sends strokes to the keyboard buffer is impossible without a security breaching hole from the browser into the OS.
