Question

請問有誰能幫助我設計產品卡，當我們單擊添加到購物車按鈕時，添加按鈕響應時，應將其更改為-1 +，然后單擊+號，數量增加而-號上數量減少，該卡應使用HTML，CSS和JS開發

你期望這樣嗎？

  $('.minus-btn').on('click', function(e) { e.preventDefault(); var $this = $(this); var $input = $this.closest('div').find('input'); var value = parseInt($input.val()); if (value > 1) { value = value - 1; } else { value = 0; } $input.val(value); }); $('.plus-btn').on('click', function(e) { e.preventDefault(); var $this = $(this); var $input = $this.closest('div').find('input'); var value = parseInt($input.val()); if (value < 100) { value = value + 1; } else { value =100; } $input.val(value); }); $('.like-btn').on('click', function() { $(this).toggleClass('is-active'); });
