var rightMouseClicked = false;

function handleMouseDown(e) {
  //e.button describes the mouse button that was clicked
  // 0 is left, 1 is middle, 2 is right
  if (e.button === 2) {
    rightMouseClicked = true;
  } else if (e.button === 0) {  
    //Do something if left button was clicked and right button is still pressed
    if (rightMouseClicked) {
      console.log('hello');
      //code
    }
  }
  console.log(rightMouseClicked);
}

function handleMouseUp(e) {
  if (e.button === 2) {
    rightMouseClicked = false;
  }
  console.log(rightMouseClicked);
}

document.addEventListener('mousedown', handleMouseDown);
document.addEventListener('mouseup', handleMouseUp);
document.addEventListener('contextmenu', function(e) {
    e.preventDefault();
});
