你好，



是否有任何方式在javascript或jquery中限制用户屏幕截图我搜索了很多并且只得到了这个东西。

Hi there,

is there any way in javascript or jquery to restrict user from taking screen shot I searched much and got this thing only.

window.addEventListener("keyup",kPress,false);
function kPress(e)
{
var c=e.keyCode||e.charCode;
if (c==44)
{
 alert("print screen");

 }
}

谢谢

推荐答案

想一想，你会看到它：如果用户在浏览器中看到某些内容，它已经在客户端。 限制任何事情都为时已晚。几乎没有任何意义。

Just think a bit, and you will see it: if a user sees something in the browser, its is already on the client side. It''s too late to "restrict" anything. And hardly may make any sense.
