我试图从输入中获取值，如果值= 1,2,3 ...以显示内容，否则，如果值= 4,5,6 ...显示其他内容。我几乎可以正常工作，然后出现故障。我已经玩了很久了。任何人都可以快速浏览一下，并指出我在哪里弄坏了它。
var amount = $(".quantity-wrapper > .input-text").val();
if(amount = '1') {
$('.product-addon-one-attendee').show();
}

最佳答案
if(amount = '1') // it is assigning not the comparision
正确的比较方式
if(amount === '1')
