Javascript check if left mouse button is clicked

Question

I have this code to detect mouse down. However on android phones, mouse down for a long time often converts to a right click. Is there a way I can only get information about left mouse click?

var mouseDown = 0;
document.body.onmousedown = function() { 
  ++mouseDown;
}
document.body.onmouseup = function() {
  --mouseDown;
}

using this as the code below

if (mouseDown){
xyz happens
}

Still a beginner, please tell me what to change in both the codes.

Thanks

Just check `onmousedown = function(e) { e.button; }`, 1 left 2 middle 3 right — Satpal, Nov 16 '16 at 12:38
Phones generally have their own tap events, but with a regular mouse you'd just check if `event.which === 1` — adeneo, Nov 16 '16 at 12:38
why don't you use the touchstart and touchend events instead of mouse down or mouse up. — Hassan ALi, Nov 16 '16 at 12:43

This might help you,

$(document).ready(function() {

  $(document).mousedown(function(e) {
      if (e.which === 1) {
          alert("left");
      }else if(e.which === 3){
          alert("right");
      }
  });

});
