You could try that:

$(document).on('mousedown', 'a[href]', offBeforeUnload)
    .on('mouseleave', 'a[href]', function () {
        $(window).on('beforeunload', windowBeforeUnload);
    });



function offBeforeUnload(event) {
    $(window).off('beforeunload');
}

function windowBeforeUnload() {
     if (!confirm("some message here")) { 
          return "Are you sure?"; 
      } else{ 
        return false; 
      } 
}

$(window).on('beforeunload', windowBeforeUnload);
