当用户选择高档酒店选择和/或底特律时，当我点击计算总成本时，每个选项都会返回值0。我给他们分配了正确的价值我很困惑为什么它没有加上我与这两个变量中的每一个相关联的价格。我不认为我的其他陈述是错的......有人可以给我一个暗示，为什么它可能不起作用？

Answer 1

当用户选择高档酒店选择和/或底特律时

您在这两个地方拼写错误checked。在这种情况下，cheked将返回undefined这是假的。因此，您将获得0而不是预期的数字

您需要的只是修复

else if (document.getElementById("detroit").cheked){

和

else if (document.getElementById("upscale").cheked){

JavaScript计算？
