How to detect right click + left click

Question

I am building a game

And I need to do something when the user clicks on the right mouse button, holds it and then presses the left button

Answer 1

Try

var hold=false;

function check(e) {
  if(e.button==2) hold=true;
  if(e.button==0 && hold) console.log('action');
}

function release(e) {
  if(e.button==2) hold=false;
}

function noContext(e) { e.preventDefault(); }

.box { width: 100px; height: 100px; border: 1px solid black;}

Hold right mouse button and press left (on sqare)
