我正在编写此 javascript 代码以禁用 Ctlr+c 和 Ctlr+v、prenscreen、ALT+TAB、Ctlr+S 和 PrintScreen 键。
<html>
<head>
<script language="javascript">
function Disable_Control_C() {
var keystroke = String.fromCharCode(event.keyCode).toLowerCase();
if (event.ctrlKey && (keystroke == 'c' || keystroke == 'v')) {
alert("let's see");
event.returnValue = false; // disable Ctrl+C
}
}
</script>

<body onkeydown="javascript:Disable_Control_C()">

- I don't like when browsers do this to me, and
- It's easy to work around, and
- This doesn't count as "secure" by any definition, but
- 我不喜欢浏览器对我这样做，并且
- 这很容易解决，而且
- 根据任何定义，这都不算作“安全”，但是
Use element.on(?:copy|cut|paste)
使用element.on(?:copy| cut|paste)
<body oncopy="return false" oncut="return false" onpaste="return false">
回答by Sachin
you can use it jquery for this. You just need to bind the cut, copyand pastefunction with your element.
您可以为此使用它 jquery。您只需要将cut,copy和pastefunction 与您的元素绑定。
And add this Jquery script:
并添加此 Jquery 脚本：
$(document).ready(function() {
$('#Selector').bind('copy paste', function(e) {
e.preventDefault();
});
});
