disable right click in javascript

问题

When I was trying to disable the right click, it is not working. I tried with below code.

document.onclick = function(e) {
  console.log(e.button);
  if(e.button == 2){
    e.preventDefault();
    return false;
  }
}

Based on below link only I tried. Disable Right Click in website

I tested this code in Chrome and Firefox. Every time I am getting the right output only in console. I mean "0" for left click and "2" for right click.But still the default action is happening. May I know the reason.? Thanks in advance.

You are using wrong event. For right click you should use oncontextmenu. You used onclick which obviously don't fire in right click and hence the loop doesn't evaluate to true in this case.

document.oncontextmenu = function (e) {
    console.log(e.button);
    if (e.button == 2) {
        e.preventDefault();
        return false;
    }

}

Only three lines of code can disable right click on a web page that is given below:

$("html").on("contextmenu",function(e){
   return false;
});
