JavaScript implementation prohibits right-clicking and F12 to view source code_javascript skills

The function is very simple and the code is also very concise. There will be no more nonsense here. I will provide the source code directly and friends who need it can take it away directly.

Copy code The code is as follows:

function click(e) {
if (document.all) {
if (event.button==2||event.button==3) { alert("Welcome to Humble House. If you need any help, please contact the webmaster! Thank you for your cooperation!!!");
oncontextmenu='return false';
}
}
if (document.layers) {
if (e.which == 3) {
oncontextmenu='return false';
}
}
}
if (document.layers) {
document.captureEvents(Event.MOUSEDOWN);
}
document.onmousedown=click;
document.oncontextmenu = new Function("return false;")

document.onkeydown =document.onkeyup = document.onkeypress=function(){
if(window.event.keyCode == 123) {
window.event.returnValue=false;
return(false);
}
}
<--123——112 is the code number of F1-F12-->

This is so that others don’t look at your code. For those who don’t understand, if you are an experienced person, you can’t prevent it!
