Question

在这里，有谁能帮助我设计产品卡，当我们单击添加到购物车按钮时，添加按钮响应时，应将其更改为-1 +，然后单击+号，数量增加，然后-标志数量减少，应使用HTML，CSS和JS开发卡

您期望这样吗？

  $('.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');
});
