Answer 1

<script type="text/JavaScript">   

var whichButtonClicked = function (e) {
    var e = e || window.event;
    var btnCode;

    if ('object' === typeof e) {
        btnCode = e.button;

        switch (btnCode) {
            case 0:
                console.log('Left button clicked');
            break;

            case 1:
                console.log('Middle button clicked');
            break;

            case 2:
                console.log('Right button clicked');
            break;

            default:
                console.log('Error: ' + btnCode);
        }
    }
}
