jQuery: Detecting pressed mouse button during mousemove event

Question

I tried to detect which mouse button -if any- is the user pressing during a mousemove event under jQuery, but I\'m getting ambiguous results:

no button press         


        

Answer 1

As of the date, the following works on Firefox 47, Chrome 54 and Safari 10.

$('#whichkey').bind('mousemove',function(e){
    if (e.buttons & 1 || (e.buttons === undefined && e.which == 1)) {
        $('#log').html('left button pressed');
    } else if (e.buttons & 2 || (e.buttons === undefined && e.which == 3)) {
        $('#log').html('right button pressed');
    } else {
        $('#log').html('no button pressed');
    }
});
