Answer 1

Finally I solved the problem by using each function

$('.mh60 a').each(function(){
    var mc = new Hammer(this);
    var currentEle = $(this);
    mc.on("press", function() {
      currentEle.addClass('active');
    });
 });

Answer 2

Why do you use a for? Try changing your code like this

var selectProduct = $('.mh60 a');
selectProduct.Hammer().on("press", function() {
  $(this).addClass('active');
});
