$（'.test'）。单击（函数（）{

**EDIT**
did this but not sure how to get the button that was clicked. I can get the data by this, but I dont know if the deny was clicked or submit was?

    var id = $(this).children('.giftcardaccount_id').text();


});

$('.test').click(function() {
    var id = $(this).find('.giftcardaccount_id:first > span').text();
});
