推荐答案

使用jQuery，您可以通过侦听keydown事件来禁用它:

With jQuery you can disable it listening to the keydown event:

$(document).on("keydown",function(ev){
	console.log(ev.keyCode);
	if(ev.keyCode===27||ev.keyCode===122) return false
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

键代码27代表ESC键，122代表F11.该产品已在chrome中进行了测试，也许对于其他浏览器可以是其他编号

keycode 27 stands for the ESC key and 122 for the F11. This was tested in chrome, maybe for other browsers can be other number
