How to disable printscreen with javascript?
I want to make function in javascript which change value of clipboard after the printscreen was used. Is that possible?
$(document).keyup(function(e){
if(e.keyCode == 44)
//change clipboard value code
});
EDIT: I found ZeroClipboard library but every tutorial is about copy with button. I want just change the value of clipboard.

There is another way to disable Print Screen in your website (it worked for my website). Click here to go to my Pen (Codepen.io). Here is also a snippet:
document.addEventListener("keyup", function (e) {
var keyCode = e.keyCode ? e.keyCode : e.which;
if (keyCode == 44) {
stopPrntScr();
}
});
function stopPrntScr() {
var inpFld = document.createElement("input");
inpFld.setAttribute("value", ".");
inpFld.setAttribute("width", "0");
inpFld.style.height = "0px";
inpFld.style.width = "0px";
inpFld.style.border = "0px";
document.body.appendChild(inpFld);
inpFld.select();
document.execCommand("copy");
inpFld.remove(inpFld);
}
function AccessClipboardData() {
try {
window.clipboardData.setData('text', "Access Restricted");
} catch (err) {
}
}
setInterval("AccessClipboardData()", 300);body {
background-color: #00FF00;
